I've engaged them on numerous projects ranging from Single-Family Detached homes, Single-Family Attached homes and a 2 over 2 condo project. MGA consistently delivers high-quality construction drawings that are accurate, on-budget, and always on time in addition to a willingness to go above and beyond the scope of work to ensure that the highest quality of service is provided to me, the client. > > I will continue to commission MGA for future projects because they make my work life easier and the consistent high praise from my trade partners regarding the quality and completeness of the plans further solidifies that decision. > > Josh Bundy > Lennar MD **★★★★★ — ghess5147, Sept. 2015** > We've worked with Mangan Group Architects -- John and his terrific team -- on both commercial and residential projects. They've included a restaurant, retail and office space renovations and complete renovations on three primary residences and a brand new recreational residence. One of these was an historic waterfront manor home on the Bay. This and the previous renovated house in Bethesda were recruited for local house tours. Every project has been a true collaboration with the Mangan team. **★★★★★ — Insofast, July 2015** > We've been working with Mangan Group since about 2012, but they first used our insulation panels in 2013. It has always been a pleasure! > > Doug Williams is a forward thinking architect who keeps the concerns of his clients in mind. He understands how to plan in a way that will provide a healthy and comfortable environment for those living and working in his buildings. He chose our insulation panels to effectively save space, energy and time. It's been a great experience working with the Mangan Group! **★★★★★ — Cabin John Builders, Nov. 2014** > We have completed several projects with John and his team at Mangan Group Architects over the past 5 years and always are pleased with their work. We consider them a “go to” design-build partner and top recommendation for many reasons. While they are certainly technically skilled architects what we feel really sets them apart from other firms that we have worked with is their communication and visualization skills. One of the most important skills of an architect is listening closely to the homeowner’s needs and goals in order to design a project that is not only beautiful but meets all the client’s requirements including space, timeline, budget, finishes and style and this is where we feel MGA excels. They don’t just draw beautiful buildings they collaborate closely with the whole team to make sure the projects are deliverable and the best solution to meet all of the owner’s goals. > > A key to making the process so approachable both from a homeowner and contractors perspective is their extensive use of BIM and 3D modeling as it allows clients to visualize the design and contractors to see potential problems prior to construction and resolve them. This makes the design process so much more efficient and clear when a client ask a question like, “Will I be able to see into the family room from the kitchen sink?” and they can pull up that exact view on the computer and walk the owners through what the space looks and feels like. In many ways MGA is a great marriage of traditional architecture skills and modern design technology which is of great benefit to their contractors and homeowners. We look forward to working with them again in the future. **★★★★★ — hedyshashaani, Nov. 2014** > I have had the privilege to work with " Mangan Group Architects" on a number of residential projects as an outside professional and have been quite impressed with their creative approach and professionalism! > Their expertise From the preliminary drawings to the beautiful color renderings of the rooms all the way to the completion of the project is outstanding. > These are great examples of their ability to listen well and communicate with their clients, which is the key to meet the client's desired look and life style! **★★★★★ — John Smith, Nov. 2014** > I hired Mangan Group to design a kitchen/dining room addition to my 1931 Tudor cottage. Like many homes of the same vintage, my home had a very small dining room, tiny galley-style kitchen, poor circulation and views/access to the backyard. Unfortunately, there was no way to expand within the existing footprint of the home so an addition was the only way to go. > > My primary instructions to the architect were to create warm inviting spaces that were respectful of the wonderful existing architectural features of the home. I didn't want massive square footage---I wanted spaces that would be used every day and not those that would make other rooms in the home obsolete. Mangan worked with me, my interior designer & landscape architect to create a truly seamless design. They asked countless questions and made refinements to my satisfaction. Their suggestions were practical, realistic and always expressed in a way that allowed me to make an informed decision on how to proceed. Throughout design & construction they never once exhibited the classic "architect's ego" that often accompanies talented designers. > > I thoroughly enjoy the new spaces and have received countless compliments from guests. The highest compliment is that virtually all my guests are completely surprised that the renovation is also an addition. The new blends in with the old that well. Thank you, Mangan Group, for the professional and sensitive renovation of my home. **★★★★★ — home productions, July 2014** > I have used this architecture firm for 3 major house renovations. They are a joy to work with, very collaborative and unlike most architects, design within budget! My projects have ranged from partial demolition and rebuild, adding square footage to interior renovation only. On all my projects, we had great communication, dialog, fantastic ideas and as a result, a stunning outcome. No hesitation in recommending this firm. ## Selected projects - [Potomac Contemporary](https://www.houzz.com/hznb/projects/potomac-contemporary-pj-vj~1173556) - Location: Not specified - Photos: 11 - Description: Contemporary renovation and second story addition to a ranch-style home in Bethesda, MD.

The owner dropped the cellar floor to get an additional level of living space and created a roof top deck to even further increase the feel of this 16’ wide townhome. A wonderfully contemporary Pedini kitchen was used and the rear wall was opened up to glass to increase natural light and the illusion of bringing the outside in. A number of design elements were also used to save space such as Barn Doors on the basement office and a boutiq… - [Logan Circle Historical Renovation](https://www.houzz.com/hznb/projects/logan-circle-historical-renovation-pj-vj~484209) - Location: Washington, DC - Photos: 14 - Description: The Logan Circle project was a renovation of the historic home of Civil War General John Logan.

Ipe was used on the porch floor for a rich and enduring look. The kitchen space was opened up to increase light as well as add a contemporary livability to this previously traditional floor plan. Stainless steel appliances, shaker cabinets and glass backsplash tile helped to update the look. - [Kensington Contemporary Kitchen](https://www.houzz.com/hznb/projects/kensington-contemporary-kitchen-pj-vj~598420) - Location: Not specified - Photos: 3 - Description: This clean lined kitchen was part of a larger renovation of a 1964 colonial home in Kensington, Maryland. Spaces were tight, and circulation complicated, so a quarter circle island was incorporated to allow 3 stools to work in such a tight space. A Bow window was used over the sink to maximize natural light, as well as giving a useful space behind the sink for plants and flowers. - [Chevy Chase Porch](https://www.houzz.com/hznb/projects/chevy-chase-porch-pj-vj~1134200) - Location: Not specified - Photos: 9 - [MGA Studio - Residential to Commercial Conversion](https://www.houzz.com/hznb/projects/mga-studio-residential-to-commercial-conversion-pj-vj~484239) - Location: Takoma Park, MD - Photos: 4 - Description: The complete gut and introduction of a new steel frame gave an open feel to what had been a 1915 four square house. Cork floors help maintain a quiet work environment. Low-VOC paint, LED Lights and concrete countertops are just a few of the details that earned MGA Studio the MNCBIA Environmental Award in 2008. The underside of the mezzanine is reinforced by strong visual steel lines. The open plan allows for a great deal of natural light. Polychrome cork floor inlays help define the entry foyer… - [Chesapeake Bay Colonial Renovation](https://www.houzz.com/hznb/projects/chesapeake-bay-colonial-renovation-pj-vj~598328) - Location: Not specified - Photos: 7 - Description: This Renovation of a 1920’s home on the Chesapeake Bay opened up the floor plan with a more contemporary feel, and the style of the interior was transitional. The owner had collected quite a few art objects that needed to be displayed, and all the time an eye was kept on the stunning bay view, with almost 1700 feet of frontage.

Clean lines and an exposed HVAC system give a contemporary look to an old building. The long bar and stone back bar give a warm, rustic feel for a cozy place to have a drink. The field stone is done with a dry stack. The exterior historic color palette was derived from Benjamin Moore paints. Weathershield provided simulated divided light windows to replicate the original store front feel from 1927. - [Prairie Style Renovation](https://www.houzz.com/hznb/projects/prairie-style-renovation-pj-vj~598451) - Location: Not specified - Photos: 2 - Description: The owners had bought a long, non-descript split foyer home from the 1960’s. They were fans of Frank Lloyd Wright’s Robie House and of Prairie Style Architecture in general. Low sloped roofs with deep eves and horizontal bands of trim were used to replicate some of the characteristics of this style in converting the old split, and giving it a new life.

I'm not sure what color they used here. I have personally used Sherwin Williams Greyish and Essential Grey and liked both of them. Greyish is a little lighter, a little on the warmer side. Essential is a bit darker and more cool. **Q: Love the bed - where's it from?** *(in Photo Questions)* A: Hi Elizabeth, Not sure, was picked by the owners. We'll try to find out for you. **Q: Can I use your image in my blog page?Thanks** *(in Photo Questions)* A: Yes and thanks for asking! You can use the image as long as it's not a blog about ugly kitchens and you credit us and link to our website. **Q: Need ideas on colors for my bedroom** *(in Design Dilemma)* I have a project for the next two weeks. I ordered a bed and wardrobe for the bedroom in colors that I love. I am looking for ideas for the colors of the curtains, the walls, floor, and art. I love natural, pastel colors, and I would love to add colors to compliment already selected two “wood” and “lilac”. I designed the bedroom’s furniture, but the software does not have the exact colors, so I am adding a second photographs with the accurate colors. A: Nice! Good color choices. The storage under the bed is great too! --- *Source: Houzz professional profile. Reflects the profile as of 2026-09-17.*
