Additions & Elevators in Silver Spring, MD

In-Law Suites, ADUs and Granny Flats 

Elevators, Stair Lifts and Platform Lifts 
With over 40 years of experience designing and building in-law suites, accessory dwelling units (ADUs), and granny flats, we understand that these projects involve far more than construction details. First and foremost, it is an honor to help bring families together. We genuinely think about the comfort, safety, and joy our clients will experience once their new space is completed. These living spaces come in many sizes and configurations. Whenever possible, a single-level layout is ideal; however, lot constraints, setbacks, or zoning requirements sometimes make a one-story design unfeasible. In those cases, thoughtful planning and accessibility solutions become even more important. Floor plans typically begin around 300 square feet and increase based on needs and budget. Below are several key considerations to keep in mind. 

 

   

Bathroom Safety and Universal Design

We have been designing zero-threshold (curb less) showers for decades. The number of accidents that occur in residential bathrooms-particularly in showers-is surprisingly high. For this reason, we take a proactive approach to bathroom design, carefully evaluating every detail to minimize risk. 

 

Key considerations include:

• Strategic placement and quantity of grab bars
• Countertop heights
• Cabinet styles and accessibility
• Adequate clear floor space
• Commode height and positioning
• Shower valves and showerhead selection
• Door sizes, types, and swing direction
• Tile selection and slip resistance
• Radiant heated floors
• Layered, well-placed lighting
Thoughtful design at this stage can significantly improve safety, comfort, and long-term usability.

 

Kitchen Design 
Kitchens in in-law suites and ADUs are generally more compact than those found in a traditional 2,500-square-foot home. Making the most of every inch is essential. Careful planning, along with researching products that offer efficient storage and functionality, ensures the space remains both practical and inviting. 

Entrances and Access 
The entry to the new living space plays a major role in overall design. Some families prefer an entrance that connects directly to the main home, while others want a fully separate exterior entry. Sidewalks incorporating gentle ramps often provide a seamless solution, and in some cases, a composite deck is the best option. Grade changes and door placement typically drive these design decisions. 

Elevators, Stair Lifts and Platform Lifts 
Choosing the right vertical access solution depends on the layout, budget, and long-term needs of the homeowner. 

 

Garage Access Considerations 
For some individuals with mobility challenges, entering through the garage using a specially equipped van can be very convenient. The challenge then becomes transitioning from garage floor level to the main living level. While ramps are an option, it is important to remember that even a 14-inch height difference may require a ramp 14 feet long or more. In many cases, a two-car garage effectively becomes a one-car garage to accommodate space requirements. 

 

Platform Lifts 

Platform lifts are an excellent space-saving alternative to ramps, especially in garage applications. Similar to a compact elevator, a wheelchair or standing user rides on a typically 5' x 5' platform that raises to a first-floor landing. Safety gates provide secure entry and exit. 

Stair Lifts 

Stair lifts are often the most budget-friendly option and have been used reliably for many years. While they once required a straight staircase, modern systems now accommodate mid-landings, turns, and multi-level transitions. When designing new staircases, a 4-foot-wide stair tread is recommended to ensure ample space for those not using the lift. 

 

 

Residential Elevators 

Residential elevators are becoming increasingly popular. We recently completed a project where the elevator traveled from the basement to a main-level office, and up to the primary bedroom providing full home accessibility for a client with back issues. Installing an elevator on the exterior of a home is generally less invasive than retrofitting one inside, which often requires structural modifications such as floor cutting, beams, and columns. 

 

Every successful project begins with understanding the client's needs. Great design starts with the people who will use the space, followed by a clearly defined budget established upfront. In many cases, building on the first floor is more cost-effective. For example, if access to the basement or second floor is not required, eliminating the need for an elevator can significantly stretch the budget while still meeting all mobility and comfort goals. 

 

Thoughtful planning, experienced design, and attention to detail ensure these spaces are safe, functional, and welcoming-now and for years to come
