We selected Wiedemann Architects for their ability to design beautiful homes under challenging situations. The property is situated on the banks of the Potomac with federally-protected trees, wildlife, and views of Mt. Vernon. During the design phase, Greg and Felix were excellent listeners and understood our family's vision. As a "family gathering place" and future retirement home, we wanted a house built for longevity -- one our family could enjoy for generations.
Given the property's unique location, it was important to have a home that was historically relevant yet also provided the modern amenities one would expect in today's world. Greg and Felix turned our vision into a beautiful modern farmhouse that blends with the natural environment and offers panoramic views from almost every room. They worked with numerous stakeholders, on our behalf, to ensure approval at all levels of government.
We couldn't be more happy with our special family retreat! Thank you Wiedemann Team!

-Project: Bright and Airy Kitchen and Family Room-
We couldn't have been happier with our team from Wiedemann Architects! We would highly recommend Wiedemann for any architectural project you may be considering.
We worked directly with Greg and Gaby throughout the project and they where there from day 1 through completion to help answer all of our questions and come up with solutions that were perfect for us! The entire Wiedemann team was professional, knowledgeable, while delivering the highest-quality plans, project scope & details, along with a timeline and budget that kept us on track with our project goals. The attention to detail was stellar and the final result was exactly what we were looking for! If you're a perfectionist, this is the right team to work with! At times, I'm sure I wasn't easy to work with - but Greg and Gaby were very patient with us as we evaluated all of our options and they helped guide us down the right path to a beautiful new kitchen and family room addition.
We couldn't give a HIGHER level of recommendation !

We had seen a project in our area that Wiedemann had done and liked it. We met with Greg (as well as two other firms) and we both agreed that he was the one to work with. He and his associate, Gaby, immediately picked up on our goals and style and were flexible when we threw them curveballs. They brought great ideas to the discussion, were always enjoyable to work with, stayed on top of the project and the builder, and generally made it a fun experience. We are thrilled with the outcome. We loved their low-key but professional approach, their eye for detail and their follow through. We recommend Wiedemann Architects whole heartily.

We've been living in our new house for a little more than a year now, and we love it more every day. This was our second time working with Greg: previously, we renovated and expanded a 1920s Sears Craftsman. That was a fun and rewarding experience, and the result was great, so, of course, we turned to Wiedemann Architects again when we decided in 2016 to build a new house. Only this time we wanted something very modern--lots of glass and sunlight, open floor plan, living space and master suite together on one floor. Greg and his associates, Felix Gonzalez and Lindsay Field, worked diligently to translate what we wanted into something that in every way makes living here really special. In addition to the Wiedemann team, we also engaged McNamara Brothers, Inc. as our general contractor and Lila Fendrick Landscape Architects as our landscape architects. Both were highly recommended by Greg, and both did an outstanding job.

When we began to look for an architect to work on our 1914 Royal Oak farmhouse, McNamara Builders recommended Greg Weidemann -Weidemann Architects From our first meeting, Greg listened carefully to our vision for our home. Greg and Andrew Dan designed a beautiful plan – addressing every detail of our home with great patience and care. Greg and Andrew skillfully combined original portions of the home with new - creating a “new/old” home that is better than we could have imagined. Old homes offer plenty of surprises during renovation but Greg handled all issues quickly and professionally. Weidemann Architects provided an efficient, thoughtful and client-focused process from planning through project completion. We thoroughly enjoyed working with Weidemann Architects and offer our highest recommendation.

As an architectural photographer, I have known and worked with Greg Wiedemann for over 20 years, photographing his finished projects for marketing and award submissions. Each project is executed with such incredible design sense and knowledge of proportion, that it is a joy to create photographs of these residences. I highly recommend Wiedemann Architects - everyone I know who has hired this firm always has had great things to say - very complimentary.

As general contractors in the Washington area, we have worked with Greg Wiedemann and his staff at Wiedemann Architects for well over twenty years. Greg’s easy, graceful style, his disciplined attention to every detail, and his persistence in the construction phase of the project all combine to make a consistently excellent product. Being the GC on his team is an uplifting experience, where professionalism and the highest standards are the predictable result of the process. We would recommend Wiedemann Architects to the discerning homeowner without reservation.

Wiedemann Architects has done numerous projects for us over the course of 18 years including our home in VA and our vacation home in WV. We could not have been more pleased with every aspect of the projects. Wiedemann Architects listened to our needs and desires and turned them into more than we could have dreamed of. The quality of their work coupled with their professionalism continues to draw us back to them when the need arises. 5 stars is just not enough!

We hired Wiedemann Architects to oversee the total renovation of a mid-century modern house in Mohican Hills, Maryland. Our 1950s house is situated on a hilly, wooded lot overlooking an old pool. The design objective was a modern house that was mostly glass in the back to take advantage of the lot, yet one that retained its original façade on the front. While the project had plenty of challenges, Greg and his team (Mitch Prince and Lindsay Field) did an exceptional job. The final project is a light filled modern space with an open staircase leading to a lower level with a poured concrete floor. Greg had really good insights and suggestions about the space, and he was flexible and willing to listen to our input. Greg also led the selection of our contractor, McNamara Brothers. Greg and the McNamaras worked very well together, and the project was delivered on budget and ahead of schedule. We are extremely pleased with the results. We would be happy to recommend Greg and Wiedemann Architects for any project, regardless of size and complexity.

We wanted to make several changes in our recently purchased, high-end condo in downtown Bethesda. We asked around and interviewed several architects, and ultimately hired Wiedeman Architects LLC. Our project grew in size and scope, as most projects do, and took several months to complete. Greg worked to re-create a relatively dark and asymmetrical space into an amazing contemporary space with clean lines, lots of light and glass and enough wood to make it warm and inviting. The master piece is the floating glass staircase! Greg was more than open to the idea and took to it with a passion; the result is amazing. Greg has great vision and patience, he was a pleasure to work with. Lindsay Field, Greg's assistant architect was absolutely great to work with as well; she has an enormous eye for detail and she worked with us as we decided on furniture sizes and placement, fixtures etc. We did not use a designer, and, because of the support of Greg and Lindsey, never really needed one. Finally, the administrative part was so easy: Greg would approve the builder's invoices and approve the charges, and send it on to us for payment, and the Wiedemann invoices were detailed and organized. In summary, our project was challenging and complex on many levels, and could have been a headache for us, but, in great part because of the Wiedemann Architects Team, it was a great experience with amazing results that we are very happy with!

Greg designed a portico for the front of our house. It is perfect and is so much more in keeping with the rest of the house. He and his staff were easy to work with, and provided excellent answers when we and the builders raised questions. But, Greg and his staff had provided us with detailed and appropriate design details that made the total redesign of our kitchen (after 25 years) even better than we anticiapted.
