Second story, kitchen, bathroom and in-law suite additions.

Our team designs precisely and creates the space that fits your lifestyle, tied into the existing house so the addition reads as part of the original rather than bolted on.
Additions are the most permit-heavy work we do. Zoning setbacks, lot coverage, structural loads and utility routing all have to be settled before design is final, which is exactly why local experience matters more here than anywhere else.
Addition Types
Four ways to add the space you need.
Kitchen additions
Extend the kitchen out rather than reorganizing around a footprint that was always too small.
- Expanded prep areas and pantry
- Island and seating options
- Better daylight and outdoor access
Bathroom additions
A new primary or guest bath where there was not one before.
- Custom layouts for primary or guest baths
- New plumbing routing and venting
- Matched finishes with the rest of the house
Guest bedrooms and in-law suites
Private, self-contained space for family, guests or multi-generational living.
- Bedroom, closet and living area
- Ensuite bathroom options
- Separate entry where zoning allows

Frequently Asked
Addition questions
Yes. All additions in Virginia require building permits. DZALA handles the permit applications with your local county, including zoning review, and tracks each inspection.
Most additions span 3 to 6 months from permit approval to completion. Smaller projects may finish in 8 to 12 weeks, while larger second-story work typically requires 4 to 6 months.
That is the point of the design phase. We match rooflines, siding, window proportions and interior trim so the addition reads as original construction rather than an obvious extension.
Usually yes. Additions are built largely outside the existing envelope, so we can keep the house livable until the point where we open the connecting wall.
