Allison Ong Shreffler, Architect / AOS Architect

I couldn’t be happier with the work Allison did designing my family’s new home. From the initial consultation to the final plans, she listened to my ideas, inspiration, and “wish list” items and brought them to life with vision and expertise. Allison was professional, communicative, and attentive to every detail throughout the process. I’d highly recommend her to anyone looking for an architect who has vision and talent.

We used Allison's services to update our 80s brick ranch by adding a porch, and the final product far exceeded our expectations. Her team was brilliant at incorporating the updates we had already done on our own and tailoring the design to our specific tastes. During the design process, they listened to our feedback and came back each time with adjustments. They were easy to work with from beginning to end. They gave us recommendations for quality contractors. They even helped us navigate zoning board issues we encountered. Highly recommend and will use again if we need design or architecture services!

Highly recommended very good remodelling company in the loop This is the best remodelling company which I have used in my whole life

Allison is a wonderful architect, who takes great time and detail in her projects. It was very exciting seeing one of her designs come to life.

Allison Ong Shreffler is an Architect with a very creative edge. Allison's vision becomes reality through her knowledge of construction and resource of vendors in the trade. Allison is not only an architect, but also has an eye on Interior Design bringing projects to a completion in a manageable cost. Her projects are real eye catchers and also very functional.

Allison is very knowledgeable, thorough and a good designer. She listened well and was responsive to our wishes. She was also very creative in solving both design and structural issues. We highly recommend her.

We are getting ready to do a fairly large renovation, the fifth one my wife and I have done in our 28 years together. We loved the bones of the house, but found ourselves a little bit all over the place and needed someone to help us focus. After doing a search I was able to find Allison to have her work with us on concepts to help us get back on track. We are so happy we were able to have her help us as we now feel our project is back on track with a level and quality of ideas that we were not able to develop on our own. Looking back at it I feel it important to provide readers a brief summary of the methodology Allison used to get us to our own design truth. For us, the core of Allisons knowledge and wisdom as an architect and designer was quite ingeniously expressed to us through her numerous conversation with us, her sessions if you will addressing the questions of what are our aspirations for our home. Her masterful questioning/inquiry methodology, listening to us, is her key to discovery of what our hearts and soul desire for our home but which we were not able to surface and express in a meaningful way. We wanted to create beauty for our selves and or community but we did not know how to articulate it, or how to approach creating it. Through Allisons empathetic questioning she was able to provide us with the indispensable component of all successful design - that is helping us clarify and simplify for our selves the seminal design concept that we knew was missing in our momentarily frustrated and arrested design process. Thanks entirely to Allison the newly resurrected renovation ideas, theme’s and practical application of those Allision was able to synthesis from us via our numerous conversations provided her with the material content and affective/emotional content she needed from us to develop am exciting progressive series of concepts upon which we could agree and choose before we committed to commencing with the renovation. Allison’s teaching strategy, her educational strategy, her intelligent, caring, truth seeking Socratic style of questioning freed us to express our sense of beauty, aesthetic truth, affective truth and design preferences. We thought of the process in which we were so fortunately engaged with Allison as a therapeutic and liberating process. To our delight that is how we feel thanks in large part to Allison’s professional and personal commitment to our renovation project and to us as human beings.

I have worked with Allison several times over the past five years. Her eye for detail is unmatched when she is designing her great projects. I would highly recommend reaching out to her next time you have a custom project! Ryan B.

Allison Ong Shreffler created a dream home renovation for us. We wanted a larger kitchen in our 1950’s ranch and a few other changes so we hired Allison. She designed a phenomenal home renovation for my parents and they absolutely loved working with her. Allison’s creative ideas blew me away and we loved everything she proposed. The drawings were everything our builder needed to bring her vision to fruition. Thanks to the technical detail in the blueprints, the project went smoothly and quickly. We couldn’t be happier with our home renovation and we will recommend Allison and her team to our family and friends.

We redid the entire first floor down to the studs including a new kitchen and master bedroom suite. I'm relatively new to the area and did some online research to figure out who could best help me remodel the house we had just bought. After narrowing the list to three and then meeting with Allison I had a feeling she was the one who could help me develop and implement my vision. I was right. She has been amazing throughout the entire project. Not only did her design evolve into a plan that exceeded my expectations but she also helped me with everything from choosing a contractor to choosing drawer pulls. There were times when I wasn't sure exactly what I wanted and her suggestions were spot on. Allison is intuitive, flexible, accommodating, and definitely excellent at what she does. I highly recommend her.

I have had the pleasure of working with Allison on numerous projects, both professional and personal. She is top notch in her craft and the consummate professional! She truly listens to her clients and provides creative solutions and best in class designs down to the last detail! I would highly recommend Allison for your next project!

I can’t speak highly enough about this architectural firm. We’re a manufacturer of custom cabinetry. We ship all over the US and have worked with literally thousands of architects. Allison Ong Shreffler is truly a cut above the rest! Her level of detail and planning is exceptional, and her staff’s friendly, responsive service is unmatched. Not only are her clients thrilled with the final result, but they’re also pleased with how pleasantly the process was to complete their project. True professionals all around!

Allison is a very organized designer and project manager. Her designs are top notch, and she knows the processes very well.

As an outside trade rep for Pella Windows and Doors I rely on working with the best contractors and architects. Allison Ong-Shreffler & AOS Architect is, without a doubt, the best architect in the Harrisburg and surrounding areas. Allison's delightful personality and demeanor will set the tone to reassure you that you're, not only working with someone who knows their business but will also make sure you feel like you're opinion matters. Her attention to detail is incredible. Allison has a gift of being able to take people's ideas/dreams and turn them into a reality that surpasses what they originally expected. I have referred several Custom Home Contractors to Allison and they have all thanked me for it. If you are looking to build a custom dream home then AOS is the right architect for you!

We have lived in our home in Good Hope Farms for 35 years. We raised our family in this neighborhood. As we got older, we talked about downsizing and moving into a space where we didn't have to go upstairs to the bedroom and downstairs to do our laundry, but we just could not imagine living somewhere else. When we first considered adding a master suite addition to the main floor of our home, we had a difficult time envisioning the end result and moving forward. We were just playing with the idea and reluctant to seriously consider it. Allison and Becky spent a lot of time talking with us, about our needs, our wants, and our dreams. They transferred those needs, wants, and dreams into photos, videos, and plans that showed us see the finished structure. She was the support we needed to move forward. We love our addition, our new bedroom, our new bath, and our new laundry room. All conveniently located so we can age in our comfortable home. Allison is personable and professional. Allison Ong-Shreffler Architect is the best.

I was referred to Allison in early 2016 by Yingst Homes Inc. when searching for an Architect in our area for a commercial remodel project. From the onset, Allison was extremely professional and worked well with my client and their request. Unfortunately, my client chose to purchase a different property that didn't require Allison's expertise. Her response was professional and understanding of my client. Would highly recommend Allison and her company for your residential or commercial needs.

Allison was AMAZING to work with. She was receptive of our goals/ideas, responsive to our requests, innovative with her design, and her final product was above and beyond our expectations. We met on November 19,2018 and had a full concept plan with elevations within in month! I highly recommend Allison and her team!

Our project consisted of renovating a portion of the house built in 1949, removing walls, adding a kitchenette area and a full bathroom. We had an eclectic idea of melding the original asthetics with a classic modern appeal. Allison did an incredible job of listening and putting together our sense of style while maintaining a practical methodical and budget conscience approach. We could not be more pleased we the results and would highly recommend for any project.

Allison and Becky did my renderings and couldn’t be more pleased with the outcome! They’ve made my job easier and love their ideas, quality and customer service with fast efficiency. I would recommend Allison to anyone looking for an architect or designer! A great experience!

It is always a pleasure to work with professionals! We have worked along side Allison and we make a great team! She has beautiful designs and together we have extremely happy clients!

We used Allison for our home renovation and rebuild project to complete turn-key architecture and design services. Allison provided us with best-in-class service in design and development of our dream home! We would highly recommend Allison for anyone interested in architectural and design services.

Allison helped us turn our dated backyard into an oasis. She came to the rescue with her artistic and architectural sense and showed us what was possible. She patiently drew sketches, explained drawings, discussed space, and even expertly worked with us to get a variance for our amazing entertainment structure that we cherish and enjoy every chance we get. We will definitely return to Allison for our next big home improvement project.

I contacted Allison earlier this year, with a very important renovation dream, of moving three disabled family members into my home for optimal loving care. An old fashioned idea, of having multiple generations under one roof, family all together, helping to achieve one goal of health and happiness. I had the dream, and Allison had the vision, ingenuity, and creativity, and came up with a design that was beyond my wildest dreams. Every detail of the design, was drafted with each of my family member's disabilities in mind. She is a professional who is passionate about her work, and she embodies all of the strengths that one could wish for, including intellect, compassion, and attention to every detail. She was always accessible for questions, updates, and budget adjustments. I feel like she invested all of her energy in the design, as if it was for one of her very own cherished family members. Dressed to the nines, she didn't think twice about scaling a ladder into my attic to assess the roof joists, and she came up with solutions for landscaping to prevent water erosion, before the renovation could begin. She also personally chose the perfect contractor, as she knows that that relationship is key, in facilitating a smooth transition during the time of construction, while we remain living in the spaces. I can't say enough about how wonderful it has been to work with her over the past several months, and how much her work will impact my life, and the lives of my family, as the construction is about to begin.

I approached Allison with an idea for a new home. After reviewing the work of several other professionals I felt most comfortable that AOS understood the project concept. After a site visit a plan was developed with cost and material taken into consideration. Coordination with local engineering firms and suppliers ensured that the project would start on time and meet the local municipality requirements. The color plans provide a great guide for all trades involved and also as a reference for materials. The continued support and attention to the plan details are a testament to her professionalism.

Allison was recommended to us by a local contractor after we realized our home renovation project was more complicated than the standard kitchen/bath remodel. Allison from the beginning has been nothing but wonderful to work with. She is responsive to our requests and her ability to "get inside my head" was uncanny. My husband and I are adding on and renovating a 50's brick ranch. We knew we wanted a midcentury modern feel to the home - when we got our first draft of the design I was stunned. Allison managed to figure out what I wanted without being able to actually articulate what it was I wanted. Our goal is to be in this home forever - with Allison's design we will have a home that can do that. Her attention to detail is evident in her interior designs but also the exterior designs. We currently have a very nondescript brick ranch - what Allison has designed for us is not only functional but beautiful, timeless, and architecturally appropriate. I would highly recommend Allison's services without reservation. She has made something that is normally stressful and made it fun and collaborative!

We wanted to remodel our current home to create a larger family room, remodel the kitchen, and add a full bath. We hired Allison to create some plans to meet our needs. She exceeded our expectations, and her vision allowed us to go with a plan we hadn't considered. Allison is very professional, and is very attentive to the needs of her clients. She responds quickly to our concerns. We would highly recommend Allison Ong Shreffler as an architect.

My wife and I worked with Allison on designing our custom home plans her cooperation, insight and support of our effort was outstanding. As we work with builders, sub-contractors and code officials all have complemented Allison's work as complete, professional and described the plans as a great guide and a true working document. These are the professionals who see others work so by comparison their comments carry weight in the home building industry. We are very pleased and highly recommend her services

Allison was amazing to work with. She worked with us when we were under contract for our current home. We needed a new roof and wanted to ensure its color tied with a midcentury vibe we were going for. Allison's design just knocked it out of the park and she used our requirements. We look forward to slowly working our house over that fits the design she created (we're a bit obsessed with what she did). Oh, and I did I mention that she was a conplete joy to work with? Looking forward to working with her more in the future.

After searching for a piece of property for over a year, my husband and I discovered that the property we already own is our dream property. We decided to hire an architect to reimagine our existing cape cod style home. We had a lofty list of changes that we wanted to make which ultimately included lifting the roof off of our home. Allison was professional, skilled and wonderful to work with. She created a new design for us with different options to fit different budgets. We were nervous to take the leap and spend so much money but we went ahead with construction and we couldn't be happier with the finished results. Our home is now exactly what we always wanted, our dream home! The before and after changes are remarkable but never would have come to fruition without Allison's expertise and careful understanding of our desires. I would recommend her to my best friends. She was lovely to work with.

We were so pleased with Allison Ong Shreffler's professionalism, timely responses and work products and the end result was fantastic. I would 100% recommend her services!

In the hopes of purchasing a commercial property for my own design business, I contacted Allison to help me determine the required modifications for a residential conversion. Allison stepped in immediately, visited and assessed the property, took measurements, and developed professional site and floor plans to submit to my local municipality. She offered quick service and smart design options that will not only be affordable to implement, but are aesthetically pleasing. I would recommend Allison for any architectural or interior design needs—big or small! Thank you, Allison!

I chose Allison Ong Shreffler as the architect to design a craftsman style 2nd floor addition for me and I am glad I did. She did a great job with the design, which looks great and keeps some of the original features of the original character of the home. This is exactly what I was looking for and I am very pleased. She is well informed and experienced in all aspects of the job and provides excellent customer service. Everything she did was done in a timely fashion and as promised. She even went above and beyond what I expected of an architect by offering advice on several issues. For example, in the beginning, we had a discussion about some structural issues in the home and she accurately predicted the repairs a structural engineer later recommended. She was very helpful to me in dealing with builders/contractors. Finally, I have found a contractor to build the 2nd floor and I have submitted the application for the building permit. Currently I am awaiting approval and I expect to get it quickly with no hassles, due to Allison's excellent work. When I was at the borough office, the zoning officer looked over the construction drawings briefly and said the architect did a good job and he said that I shouldn't have any problems with the approval as everything appeared to be in order and looked very good. I am very pleased with her work and if you ever need an architect, I highly recommend Allison Ong Shreffler!!

I have worked with Allison on several projects over the past two years and have been impressed with her product knowledge and how detail oriented she is. Allison put a lot of thought into the projects I worked on with her to ensure that the appropriate windows and doors were being use to best compliment the overall look she was looking for. Exterior and interior colors were reviewed thoroughly with both myself and the homeowner. Allison was also very involved with the remodeler (Home-Time Remodeling) and myself to make sure everyone was on the same page up until the day the products were ordered. It was a pleasure working with AOS Architects and look forward working with Allison in the near future!

Allison designed a custom home plan for our family. She was able to customize plans that we had purchased online into a dynamic, beautiful home. She very patiently took a very high level of care into the details of every exterior and interior view of all of the rooms. She reconfigured the windows, interior ceilings, roofs, and exterior finishes into a style that was really personal for my husband & I. She also made sure that all of the rooms were designed to maximize storage and space. I was also impressed with her knowledge of new products and her enthusiasm for trying something innovative. I knew that she was the right architect for our home, and highly recommend her to anyone looking to design a new home or remodel.

I was introduced to Allison Ong Shreffler, Architect through a client while attending an event in Philadelphia and immediately connected with her philosophy to “design from the inside out.” In the midst of downsizing my home I was also transitioning into a home office environment. Facing these two daunting changes had presented with many disruptions to my life. I was experiencing a spatial disconnect that challenged me to figure out how I could successfully function inside of diminished space that could blend work life balance, and still allow me to be productive while maintaining the feeling of being able to enjoy the comfort of my own home away from work. My small design challenge was effectively solved through her consultation and direction from a distance. Her consideration to help me on this project and knowledge ultimately overcame my challenges of how to optimize and utilize my new living/work space. I highly recommend Allison and her architectural philosophy that brings not only “design aesthetics” but one that will affect how you “are going to feel when you experience the space.”

I have had the privilege of working along side Allison on a consultant basis. She is extremely thorough, dedicated and incredibly talented. She is respectful, kind and warm when interacting with her clients.

As a custom kitchen manufacturer attention to detail is so critical. It is a pleasure to work with Allison who has a keen eye, and a pays very close attention details that required us to meet some very tight tolerances. We were able to meet Allison's expectations and satisfy her customer requirements as well. We look forward to working with Allison on future projects. There is something to be said for someone who knows what she wants and can provide us the specifications. This remodeling renovation/project was quite extensive. This collaborative effort required many trades involved, and due to good plans we were yet able to meet the deadlines. Congratulations Allison on a job well done, if we can work together on any future projects, please do not hesitate to call us.

It was more than a pleasure working with Allison. She designed our new shore house in NJ after our original home was devastated by "Sandy." She demonstrated superior level of knowledge, professionalism and her attention to detail went unsurpassed. During the construction Allison was always available to help with any questions the contractors may have had. You will not be disappointed with the end result.

Alison is a joy to work with. I was looking to redesign our attic and surprise my wife with the architectural plans for the roof and dormers to expand the interior space. Alison was able to provide the drawings on very short notice, and was extraordinarily flexible and patient as we pondered and reconfigured our plans several times. When we finally did settle on a final design, she was able to translate it and come up with the drawings we actually wound up using. The final product has helped transform a barely livable space to one that screams with potential. And once we begin construction on the interior, we'll give her another call, just to hear more of her expert ideas and tasteful advice. We look forward to working with her again. Prompt, Personal and Professional.... She is HIGHLY recommended!

Allison designed my new home from the ground up. She listened intently to my ideas that I wanted in the home and made very helpful suggestions to add/delete/alter some of the things that would make it a better design and also within my budget. Her knowledge of the architectural design aspects and her practical knowledge of what works and what doesn't was extremely helpful. In the end, my new home was exactly what I wanted. Allison is a very skilled architect who is also down to earth and will go out of her way to help you achieve the design and results you are looking for. I would highly recommend her to everyone.

I have known and worked with Allison for many years. Allison has always been sensitive to budgets and construction timelines. She is responsive to inquiries and problem solving, and understands what designs would be appropriate for my target markets. Her designs have been sought after throughout my community, and I was happy that I had chosen her to design my homes.
