Plan an addition in this order: define the household problem, test zoning and site feasibility, develop the layout, coordinate structure and systems, select finishes, then finalize price and schedule.
The short answer
Early feasibility work prevents expensive redesign later. Additions can affect foundations, rooflines, drainage, HVAC capacity, electrical service, and the way old and new spaces connect.
What changes the answer for a DMV home
Setbacks, lot coverage, easements, historic review, and utility capacity differ across DMV jurisdictions. DMV homes range from historic rowhouses and older ramblers to newer suburban construction. The right answer depends on the building, lot, household, and local approval process.
What to review before requesting a proposal
- The rooms or problems the project must solve
- Existing conditions that may affect structure or building systems
- Product, finish, storage, accessibility, and layout priorities
- Permit, HOA, parking, access, or occupied-home constraints
- A comfortable investment range and contingency for unknown conditions
How to compare the options
Compare complete scope rather than isolated prices. Check what is included, what remains an allowance, who coordinates permits and inspections, how changes are approved, and what conditions could alter the schedule.
A practical next step
Collect photos, measurements, inspiration, known property documents, and a short list of must-haves. An on-site consultation can then focus on feasibility and scope instead of guessing from averages.
