frequently
asked questions
Which type of addition is right for our house?
It starts with the problem you’re solving. Need daily living space? A family-room or great-room addition off the kitchen. A parent moving in? An in-law suite or above-garage apartment with its own entrance. Out of bedrooms? A second story doubles the house without touching the yard. At your free consultation we walk the lot and give you an honest read on which options your property actually supports.
How long does a home addition take?
Real answer: months, not weeks, and anyone promising otherwise is guessing. A straightforward bump-out or family room typically runs two to four months of construction; second stories and large suites longer. Before that, design, engineering and county permitting take their own time. You get the full timeline in writing before we start, and we protect it with one project manager and our own crews.
Do you handle the architecture and engineering?
Yes, additions are structural projects, and we run the whole stack: architectural design matched to your home, structural engineering, energy-code compliance and county submissions. You see the addition in 3D renderings before anything is built, and you never coordinate between an architect, an engineer and a builder, that’s our job.
What about permits and setback rules in Fairfax and Loudoun County?
Additions live and die by zoning: setbacks, lot coverage and height rules decide what can be built before design taste enters the picture. We check your parcel’s rules up front, Fairfax County, Loudoun County, or town jurisdictions like Vienna, Herndon and Leesburg, and manage every permit and inspection from footing to final.
Can we live at home during construction?
Almost everyone does. An addition is built outside your existing walls for most of the project, and we seal the connection point until the last practical moment, so daily life continues with fences, protected pathways and a clean site. We tell you honestly which days the wall comes down and plan them with you.
Will the addition match our existing house?
That’s the test of a good addition, and where we put the design effort. Rooflines that continue naturally, siding and brick matched or deliberately complemented, windows aligned with the originals, and floors that run through at the same level. Inside and out, the goal is simple: nobody should be able to tell where the old house ends.
Does an addition need its own heating and cooling?
Often, yes. Your existing system was sized for the house it serves, and a large addition can overwhelm it. We calculate the load honestly and recommend either an extension of your system, or a dedicated mini-split or zoned unit for the new space, decided in design, not discovered on the first hot day.
What does a home addition cost?
It depends on size, structure and finish level, a bump-out and a full second story are entirely different projects. What we promise: a detailed, itemized proposal after your free consultation, the agreed price locked before construction, and per Virginia law just 30% down to start. No mid-project surprises.
