My family & I have had the fortunate opportunity to work with Tom to design a new home. Tom always responds promptly and provides a quick turnaround with high-quality work. His attention to detail is impeccable, and his creativity and ability to incorporate our feedback into the designs have been extremely important to us. **★★★★★ — Oak View Homes, Nov. 2023** > We have been Working with Kohlmark Flach Architects for over 10 years. Their design expertise and attention to detail transforms our ideas into stunning realities. From start to finish, their professionalism and clear communication make the process seamless. Their innovative approach and ability to blend functionality with aesthetics results in fantastic designs. We highly recommend Tom for anyone seeking a talented and collaborative architect. **★★★★★ — thartwig1911, Nov. 2023** > Kohlmark Flach completed a Design Build whole house renovation for us back in January of 2020. We had an excellent experience with the entire team from the early design to project close out. Tom Flach was able to decipher our vision into a wonderful living space that met all of our needs and wants. The construction team was efficient, professional, and timely. Our project was on budget and on time. I highly recommend the Kohlmark Flach team for Design, New Build or Renovation. **★★★★★ — Todd Allgier, Nov. 2023** > Tom Flach is the in-house design architect for Kohlmark Homes. We hired this contractor to build an accessory structure and decided to use Tom for the design. An Accessory structure is similar to an ADU or Granny flat. The only difference is in its use. It is a beautiful addition to our property in N. Arlington and gives us the flexibility we both need for remote work. It is just short of 1700 sq ft on 3 levels and has 2 full baths. > Tom was very attentive and responsive to our needs. He designed it with us at our kitchen table. We got everything we wanted in what was a 560 Sq Ft. Footprint. A wall of southern-facing windows. 9" ceilings on 2 floors. 2 fireplaces, and beautiful finishes. Tom wrestled with the folks at Arlington County, plan review, etc, until the plans were eventually approved. That was no small feat and not everyone is prepared to take that on. We broke ground in March of 2020 the day they formally announced covid. The total project was completed by December of the same year. Tom never let us down and caught a few construction errors before they became a problem. Our builder was honorable and made things right. I would highly recommend Tom for any project you may be considering. **★★★★★ — OYSTER BUILDERS LLC, Nov. 2023** > Tom and his team have been my go to firm for 15+ years for architecturally inspired large complicated remodels and new residential construction projects. Aside from their sophisticated taste he and his team truely care about what they do. > > Rob Lancaster > Oyster Builders **★★★★★ — Conor Black, Oct. 2023** > Awesome architect and extremely easy to work with!! > > I have worked with Tom for over 10 tens years and have recommend his team to all my friends and family. **★★★★★ — Jens Green, Oct. 2023** > If you're looking for high-end results, look no further - Tom Flach is a genius! Our house is now the talk of the town! Tom exceeded our expectations. Before using Tom, we loved the location of where we live, but hated the look of our 3 bed 2 bath ranch.... He transformed our home into a 5 bed 4 bath craftsman :) Now we LOVE the way our home looks! He's a true professional in his craft. **★★★★★ — Linda Brandwin, Oct. 2023** > Tom Flach, our architect at Kohlmark, 100% understood what we wanted in our new home. But he didn’t stop there, he made the plans better than we even knew were possible. Tom was always available to answer our questions and to help us with any decisions or issues that arose. His skill, his vision, his guidance, and integrity made this experience a lot easier for us. ## Selected projects - [Barn Transformation](https://www.houzz.com/hznb/projects/barn-transformation-pj-vj~6729178) - Location: Charlottesville, VA - Photos: 14 - Description: There’s something about Charlottesville. Once you’ve lived here, walked the Lawn, and seen the Blue Ridge, you’re part of a community, and you’ll always be able to call this place home. It’s a story we hear from so many clients. They came back to raise a family. They came back for retirement. Or they never left. They feel a connection to Virginia, to Charlottesville, and to the red brick, the standing seam, the rustic barn, or the front porch. The enduring architecture that dots our landscape is… - [Clifton Farmhouse](https://www.houzz.com/hznb/projects/clifton-farmhouse-pj-vj~6729189) - Location: Clifton, VA - Photos: 8 - Description: The owners of this historic farmhouse sought a comprehensive addition to expand the living and entertaining spaces while bringing the family together with a more open, fluid and friendly layout. The small rooms, low ceilings and dark, interior kitchen have given way to open spaces, vaulted ceilings and a spectacular relocated kitchen. A floor-to-ceiling folding door opens the entire great room to the outdoors while the visually stunning timber frame trusses support the vaulted ceiling and hint t… - [Milleens](https://www.houzz.com/hznb/projects/milleens-pj-vj~6729204) - Location: Woodbridge, VA - Photos: 10 - Description: The design of Milleens was driven by the owners desire for a three bedroom waterfront home that showcased the spectacular views and park-like setting. As nature lovers, they wanted their home to be organic, minimize any environmental impact on the sensitive site and embrace nature. Milleens is sited on a high ridge with a 45° slope to the water on the right and a deep ravine on the left. The five acre site is completely wooded and tree preservation was a major emphasis. Very few trees were remov… - [Craftsman Inspired Waterfront](https://www.houzz.com/hznb/projects/craftsman-inspired-waterfront-pj-vj~6729213) - Location: Mason Neck, VA - Photos: 7 - Description: The Owners of this riverfront property requested a home that was designed to showcase the spectacular setting while remaining comfortable for large parties or just two people. Every major room features magnificent water views and the generous use of rich woods, stone, color and scale create warm and inviting spaces despite the size. High winds, humidity, and intense reflective sun are some of the unique challenges of living on the river and needed to be addressed. To overcome these, tinted windo… - [Contemporary Solar](https://www.houzz.com/hznb/projects/contemporary-solar-pj-vj~6729224) - Location: Potomac, MD - Photos: 15 - Description: Ensconced in a neighborhood with its own wooded trail leading down to the C&O Canal towpath, the owners and their three young boys adored their pristine surroundings. If only their 1980s Colonial home shared a similar reverence for Mother Nature. Its windows were too few and far between to appreciate the views. Outdated mechanical systems and poor insulation made the house drafty and inefficient. It also had an outdated kitchen and disjointed floor plan. House-hunting forays to find something be… - [Deck House](https://www.houzz.com/hznb/projects/deck-house-pj-vj~6729234) - Location: Arlington, VA - Photos: 5 - Description: The original home was overhauled and clad in new colors and materials that blend into the surrounding woods. The four-story house with walls of glass perches on a slope leading down to lush woods and a stream. At first glance, the setting suggests you’re somewhere in the foothills of the Allegheny Mountains or the Shenandoah. But if you check your bearings, you’d discover that Arlington’s Spout Run snakes around the opposite side of the woods, and the stream is a tributary to the nearby Potomac… - [Farmhouse Transformation](https://www.houzz.com/hznb/projects/farmhouse-transformation-pj-vj~6729238) - Location: Waterford, VA - Photos: 10 - Description: It’s all about location and the owners of this dated 1990s colonial purchased the home for its spectacular views and setting. Unfortunately, the design of the existing home did not live up to its potential. An awkwardly placed mudroom blocked an otherwise magnificent view from the existing kitchen and breakfast room while the second floor turned its back on the amazing high views of the vineyard and mountains beyond. The unfinished basement did little to connect with the beautiful rear yard and… - [Ashland Farm](https://www.houzz.com/hznb/projects/ashland-farm-pj-vj~6729245) - Location: Not specified - Photos: 14 - Description: This horse country estate has a rich history tracing back to 1790. In the 1920’s, noted architect William Bottomley expanded the simple structure into a magnificent stone hunting lodge. However, in recent times, the house was unoccupied and fell into disrepair. Our clients purchased the structure with the goal of transforming the home into a summer retreat suited for large gatherings while still preserving the historic character and exterior of the home. The restoration involved complete new mec… - [Storybook Cottage](https://www.houzz.com/hznb/projects/storybook-cottage-pj-vj~6729251) - Location: Great Falls, VA - Photos: 6 - Description: This 1980’s contemporary had great curb appeal and proportions, but contained many awkward and poorly designed spaces. While the primary focus was to address the design deficiencies with additions and a more livable and useful floor plan, extensive work was done to transform the interior and exterior into a more traditional craftsman-style cottage. The addition to the right of the house addressed the need for a main level garage with an in-law suite above. By moving the garage out of the basemen… - [Bridge House](https://www.houzz.com/hznb/projects/bridge-house-pj-vj~6729253) - Location: Clifton, VA - Photos: 5 - Description: The existing three-bedroom home was originally constructed as a carriage house to serve a future estate and never intended to be a primary residence. Though full of charm, the small place lacked the space and functionality typically found in today’s homes. With a growing family and defined limitations, the long-time owners wanted to remodel and expand. We were asked to design a new foyer, living room and master suite with adjacent study above grade and incorporate an exercise room and unfinished… - [Contemporary Pool House](https://www.houzz.com/hznb/projects/contemporary-pool-house-pj-vj~6729254) - Location: Vienna, VA - Photos: 8 - Description: Modernism and traditionalism are just steps away from each other at this Vienna Virginia pool house. The main house, built by another national homebuilder, draws upon tradition, but the pool house, speaks the language of contemporary minimalism. It presents clean lines and a soaring roofline overhanging tall glass doors and clerestory windows. Great design, careful attention to detail, first-rate materials and impeccable craftsmanship have yielded a spectacular solution for outdoor entertaining.… - [Shingle Style Estate](https://www.houzz.com/hznb/projects/shingle-style-estate-pj-vj~6729256) - Location: Oakton, VA - Photos: 12 [See all 12 projects](https://www.houzz.com/professionals/architects-and-building-designers/kohlmark-flach-architects-pfvwus-pf~633579377) --- *Source: Houzz professional profile.
