Having grown up in the area, our customers knew they wanted to stay in their Fairfax home long-term. However, the original design proved to be too small for their growing family and didn't suit their needs. With the addition of an upper level on one side of the house, the family added two bedrooms and a bathroom for their children, reconfigured the home's entryway, updated all other bathrooms, and updated the basement & fireplace.

This expansive two-story home addition maximizes vertical square footage with carefully matched exterior siding and energy-efficient windows. Built on a solid block foundation, the new structure provides substantial interior living space tailored to a growing family's needs. The seamless exterior integration improves everyday functionality and long-term home value.

Design-Build Garage Addition & Remodel in Mt. Airy, MD Talon Construction Inc. recently completed this custom design-build garage addition and remodel in Mt. Airy, Maryland, creating a beautiful, high-performance space that blends modern functionality with timeless curb appeal. Designed to complement the existing property, this detached three-car garage features architectural roofing, maintenance-free vinyl siding, stone veneer accents, and black carriage-style garage doors for a clean, upscale appearance. Inside, the garage was fully finished to provide a bright, open, and versatile environment for vehicle storage, workshop use, hobby space, entertaining, or a future home gym. The vaulted ceiling design creates a spacious feel, while recessed LED lighting and modern ceiling fans improve comfort and energy efficiency throughout the space. A professionally installed epoxy garage floor coating delivers durability, easy maintenance, and a polished showroom-quality finish. As a trusted design-build contractor serving Mt. Airy, Frederick County, and surrounding Maryland communities, Talon Construction Inc. handled every phase of the project. To include the planning, custom garage design, permitting, construction, exterior finishing, and interior detailing. The completed garage addition not only enhances everyday functionality but also adds long-term value and architectural consistency to the property.

Our homeowners knew they wanted to stay in their beautiful Arlington home for the long term, so, partnered with our team at MOSS to design a main level addition that could be used for aging in place. A large, central space, currently being used as a family room, will serve as a bedroom in the future. Attached to it are a full bathroom (with safety bars and a zero entry into the shower), large closet, and same level back patio. In addition, MOSS added a pantry and laundry room to the main level.

Staircase – Custom Detailed Vertical Connection | Second Floor Addition, Toronto This staircase is a key architectural feature of the home, thoughtfully designed as part of the second floor addition to create a seamless and inviting connection between levels. Rather than feeling enclosed or purely functional, the stair was intentionally planned to remain open, light-filled, and visually integrated with the surrounding spaces. The design showcases a custom railing system, combining glass panels with a continuous oak handrail and black metal detailing, striking a balance between warmth and modern contrast. The transparency of the glass allows natural light to flow freely through the stairwell, enhancing sightlines and preventing the vertical transition from feeling closed off. From a construction standpoint, the staircase required precise structural coordination, framing alignment, and finish integration to ensure safety, code compliance, and long-term durability—especially critical when tying a new second storey into an existing home. As part of the full-home transformation, this staircase reflects Cedarstone Group Inc.’s design-build philosophy: every transition space is an opportunity for thoughtful design, craftsmanship, and cohesion, not an afterthought.

"The homeowners faced a challenge in their beloved early-1900s home: all the bedrooms were upstairs, while the kitchen was on the main floor. To make their forever home work for the long term, they aimed to “future-proof” it with an ADA-accessible primary suite that would offer comfort, functionality, and independence as they age. To bring this vision to life, we designed and built a carefully integrated addition off the back of the home. Positioned for easy, same-level access from the rear parking area via the alley, the new suite offers both convenience and accessibility without compromising the home’s historic character. Stepping through the back door, you enter a spacious, light-filled primary bedroom that seamlessly blends modern design with thoughtful functionality. The attached ADA-compliant bathroom features a barrierless shower with grab bars, a wheelchair-accessible vanity, and built-in laundry—offering both comfort and ease of use. While the suite was designed for future needs, the space currently doubles as a music room, demonstrating its versatility and intentional design. This addition not only honors the home's original charm but also provides the homeowners with peace of mind, knowing their beloved space will serve them well for years to come."

The Roger Lee designed house from 1962 was purchased by the current homeowners in almost original condition, as the previous owners elected to defer most maintenance projects over the years. The clients were able to see beyond the dated materials and finishes, single-paned glass and uninsulated walls and they approached Klopf Architecture to help them expand and update the entire home, one the family could settle into and enjoy for years to come. It was important that the new designs were aligned with Lee's original intent not only because of the client's appreciation for mid-century modern architecture, but also because the house was deemed historical. The Stanford Real Estate Office requires a stringent design review which safeguards the integrity of the community, which Klopf Architecture was happy to oblige going into their updated designs. As with many original mid-century modern homes, the house was scaled to the 1960s lifestyle where rooms were smaller and openings to views were limited and tightly framed. The original conditions defined the direction the family of four would take in updating the house and making it comfortable for their modern lifestyle. Klopf designed a full gut remodel and major addition to bring the house into the 21st century and provide the living area needed for the client's family. The newly expanded house added just about 1,100 sf to create an airy, comfortable and family friendly house, taking full advantage of the beautiful southwestern views that extend out to the hills beyond. The enclosed garage created an additional 240 sf of covered space for long-term storage. A cracked swimming pool created an eyesore taking up a majority of the backyard landscape, so it was one of the first elements to go during the transformation. Working with Outer Space Landscape Architects, the family asked for a mix of relaxing outdoor patio spaces that eventually blend into the native landscaping, extending their views outward toward the natural greenery of the trees beyond their property. Filling in the old pool was a smart way to expand the living spaces outward. The orientation of the house was designed to enjoy the views, but the original architecture provided the first homeowners with mere glimpses of the landscape outside. Klopf was able to broaden those views, continuing and extending on the original architecture to take full advantage of the unobstructed natural views across the rear facade of the house. Small horizontal openings in the primary bedroom and office were replaced with much taller windows that now follow the angled roof line upward, extending across almost all of the facade. We worked with Western Windows, whose designs included an oblique-shaped, operable casement that allowed our design to rise with the slope. A new corner office added to the primary suite, offers a bright and functional work-from-home solution that looks out at the distant views and added natural light from the expanded window configuration that now wraps around the corner. The existing lower level was designed by Lee as a utilitarian space, serving as a wet pool room with a drain in the center of the floor, bathroom, laundry and storage areas. Without the need for a pool room, Klopf was able to convert the area into a much more comfortable and functional living space with a new family room and guest suite. The new spaces enjoy easy access to a new outdoor patio through floor to ceiling, full-width glass sliders. Continuing along the rear facade, a previously exposed deck extending from the living room and hallway provided access to the backyard through a single set of stairs leading toward the side of the house which made sense when the pool was in place. The new deck was re-envisioned as an extension of the main living room and now serves as a second outdoor living room. A new slatted pergola above provides the homeowners welcome relief from the hot afternoon sun. A second set of stairs now creates a better connection to the redesigned lower level. Klopf was able to reconfigure the spaces, extending the living room outward toward the views, where the family now claims it as the heart of the home, spending a large majority of their time outdoors. Back inside, the original wood-burning Malm fireplace was beautifully restored and a gas burner installed to comply with California's strict air standards. It now rests in front of a wall of Heath accent tiles where a dated red brick wall used to stand. A new taller window brings more light and views into the refreshed interior living room. The original glass doors opposite the fireplace were replaced by larger sliders that when fully opened, create a seamless transition to the new outdoor living area so the two spaces feel like one connected space. The original utilitarian kitchen was needlessly tucked into the far back corner and closed-off, out of sight from the living room, so the clients asked Klopf to open it up and expand the kitchen forward so it felt more connected. Today the much larger kitchen is connected to the living area where a short wall with a cutout offers a visual glimpse into the kitchen and a handy pass-through counter for serving guests. A new breakfast nook was also added to create another spot where the family can gather for casual meals. Just outside, a new built-in outdoor grill and prep area extends the kitchen outside and connects to a new outdoor dining spot nestled amongst the trees, taking advantage of the views out back. Klopf was able to expand the other two bedrooms, add a new laundry room and half-bath and convert the carport to an enclosed garage to add more storage areas which was lost when the pool house was converted to the family and guest room. To maintain a historical connection to the original designs, the exterior siding was repeated on all exterior walls, a full-height stained glass window at the front entryway restored, and an interior slatted screen element repeated outside at the exterior entry courtyard and over the new outdoor living room to create a shade trellis. The new house stands proudly and shines against it's new landscaping features, while respecting and expanding on the original intent of Roger Lee's designs epitomizing the comforts of indoor-outdoor living in Northern California.
