He is professional, meticulous and creative in approach. His designs provide a seamless integration with your existing core architecture, along with integrating individual style ideas. Our current project has some very difficult circumstances and he is professionally navigating the job through to completion. I would recommend him to anyone looking for quality residential services with an attentive personal management style. **★★★★★ — Craftsman Construction, April 2012** > My partner and i have worked on several very large projects with Tom. As custom builders of very high end homes we have to work with architects very closely. Tom Ahmann was without a doubt the easiest and most acr ## Selected projects - ["Carriage House" Addition, Arlington, Virginia](https://www.houzz.com/hznb/projects/carriage-house-addition-arlington-virginia-pj-vj~61449) - Location: Arlington, VA - Photos: 3 - Description: Incorporating a his and her pair of home offices, this project presents itself as a carriage house adjacent to the main house. The two forms are joined by a linking stair which solves a split level relationship allowing for the addition to step down the hill and maintain a lower profile.

Photo © AHMANN LLC - [Porch Addition, Ellicott City, Maryland](https://www.houzz.com/hznb/projects/porch-addition-ellicott-city-maryland-pj-vj~60577) - Location: Ellicott City, MD - Photos: 4 - Description: We have created an outdoor room which borrows from the rich architectural tradition of the surrounding region. Copper covered barrel vaulted dormers and a half-round window capture views of the sky, while adding light to the “cathedral” interior and, indirectly, to the family room. Siding and colors from the existing house were incorporated into the gabled roof addition, which has defined a focus for the yard and a space for a new brick terrace. The porch extends into the family room with new fr… - [Interior Renovation, Bethesda, Maryland](https://www.houzz.com/hznb/projects/interior-renovation-bethesda-maryland-pj-vj~60575) - Location: Bethesda, MD - Photos: 3 - Description: In this residential renovation the back wing of the existing house was opened up and converted to a family library with an adjacent breakfast room and guest powder room. French doors and side lights bring new found light to what was a dark portion of the house. The flow of space now unites the front of the house with the existing deck and large back yard. A family of built-ins was created which has unified the kitchen, breakfast room and library into a spacious and orderly composition. The renov… - [One Story Addition, Potomac, Maryland](https://www.houzz.com/hznb/projects/one-story-addition-potomac-maryland-pj-vj~60573) - Location: Potomac, MD - Photos: 3 - Description: We have extended the ridge of the existing garage to roof a new room. This wing provides definition for a new flagstone terrace which overlooks the expansive rear lawn. The room and garage are linked to the house via a new conservatory. Floored in flagstone, and with tall windows and transoms, the room unites with the new terrace. With French doors to the front and rear, the conservatory becomes a foyer for garden parties and other outdoor events.

Faced in stucco with cast stone trim and stone foundation, the main house is reminiscent of a classic Tuscan villa. The clay tile roof, mahogany windows, operable shutters, and stone floors accentuate the Italian splendor.

The new space incorporates what was once a narrow play room as well as an awkward side alcove into a cohesive whole. Darkly stained cabinets and warm tone tiles are highlighted by ample lighting. Photographs © Stacy Zarin-Goldberg - [Kitchen Addition & Renovation, Washington, DC](https://www.houzz.com/hznb/projects/kitchen-addition-and-renovation-washington-dc-pj-vj~39658) - Location: Not specified - Photos: 7 - [One Story Addition, Washington, DC](https://www.houzz.com/hznb/projects/one-story-addition-washington-dc-pj-vj~37999) - Location: Washington, DC - Photos: 9 - Description: Because of the narrowness of the lot, we created the new kitchen as an atrium between the main house and the library allowing as much light into the existing portion of the house as possible. This new interior courtyard leads out to a side deck and down to the new garden shared with the adjoining neighbor. Photographs © Stacy Zarin-Goldberg - [Kitchen Addition, Washington, DC](https://www.houzz.com/hznb/projects/kitchen-addition-washington-dc-pj-vj~39021) - Location: Washington, DC - Photos: 10 - Description: Continuing the lines of the existing wrap-around porch, we were able to create a family kitchen with a raised ceiling culminating in a large skylight. The warmth of natural lighting highlights the palate of the material selection. The kitchen extends out to a new deck and yard beyond. Photographs © Stacy Zarin-Goldberg - [Addition and Renovation, Cabin John, Maryland](https://www.houzz.com/hznb/projects/addition-and-renovation-cabin-john-maryland-pj-vj~37983) - Location: Cabin John, MD - Photos: 12 - Description: By placing a small addition to the rear and a larger addition to the side, we have converted a dysfunctional bungalow into an effective family home. The additions maintain the original scale by being differentiated as discrete pieces rather than one large mass. Materials and detailing blend the parts into a cohesive whole. Inside we flipped the stair to work better with the entry sequence as well as to be more central to the enlarged home. Photographs © Stacy Zarin-Goldberg - [Addition and Renovation, Bethesda, Maryland](https://www.houzz.com/hznb/projects/addition-and-renovation-bethesda-maryland-pj-vj~37966) - Location: Bethesda, MD - Photos: 12 - Description: An open plan within a traditional framework was the Owner’s goal - for ease of entertaining, for working at home, or for just hanging out as a family. We pushed out to the side, eliminating a useless appendage, to expand the dining room and to create a new family room. Large openings connect rooms as well as the garden, while allowing spacial definition. Additional renovations included updating the kitchen and master bath, as well as creating a formal office paneled in stained cherry wood. Photo… - [Two Story Addition, Washington, DC](https://www.houzz.com/hznb/projects/two-story-addition-washington-dc-pj-vj~37955) - Location: Washington, DC - Photos: 9 - Description: A family kitchen with a focus on the yard was the Owner’s intent. Plus some space to cloister away in private luxury. Down went the useless undersized garage, and up went a two story addition. With space to drop off incoming junk, space to eat, space to lounge, space to work, and a connection to a new patio, the kitchen fulfills the goal of a room to live in. Perched above with windows all around, the new Owner’s Suite . . . Photographs © Stacy Zarin-Goldberg - [Two Story Addition, University Park, MD](https://www.houzz.com/hznb/projects/two-story-addition-university-park-md-pj-vj~37793) - Location: University Park, MD - Photos: 7 - Description: “There’s something out there,” they said at our first meeting. “We just can’t tell what it is.” A brick monolith with midget windows divided the house from the yard, so we punched some larger openings through the wall and terraced down from a treehouse sitting room - to a step-down family room - to a deck - to a patio. Now they’re out back.
