More room, without moving. Additions that blend seamlessly with your home's character and add lasting value.
When you love your neighborhood but need more space, an addition lets you stay put and grow. Additions are also among the most involved projects a home can take on — they touch the foundation, structure, roofline, and systems — which makes design-build delivery especially valuable. Donya LLC keeps design, engineering, permitting, and construction under one roof so an addition looks original to the house, not bolted on.
An addition should disappear into the house. We match siding, trim, roofing, and window lines to your existing home, and build the new structure to current energy standards — quality insulation and efficient windows — so the new space is comfortable and cost-effective to heat and cool.
Lot setbacks, height limits, and zoning vary across Montgomery County, DC, and Northern Virginia jurisdictions. We factor those constraints into the design from the start, so your addition is both what you want and what's approvable where you live. Older Bethesda and Chevy Chase homes also often need thoughtful structural planning to tie old and new together correctly.
