Common questions about home additions
Home addition costs in Baldwin County range from $150 to $300 per square foot depending on the type of addition, foundation requirements, finishes, and whether plumbing or electrical is involved. A standard bedroom addition runs $40,000 to $80,000. Kitchen expansions and second-story additions cost more. We provide a written estimate after the design consultation.
A single-room addition typically takes 2 to 4 months. Second-story additions and larger expansions take 4 to 8 months. Timeline depends on scope, permitting, and weather. We provide a written schedule before work begins.
That is the standard we build to. Roofline pitch, siding material, window style, trim profiles, and paint color are all matched to the existing structure. The addition should look like it was part of the original build.
In most cases, yes. We phase the work and install dust barriers between the active construction zone and your living areas. We will let you know upfront if any phase requires temporary relocation.
The existing foundation is evaluated during the consultation. New additions get their own foundation engineered for Baldwin County soil and wind load requirements. Connections between the old and new foundation are designed to prevent settling or separation.
Home additions in Baldwin County require building permits, and depending on scope, electrical, plumbing, and mechanical permits. DD&B handles all permitting and scheduling of inspections.
DD&B provides in-house design and engineering for additions. You do not need to hire a separate architect. If you already have plans, we can build from them after reviewing for code compliance and structural integrity.
Yes. Bathroom additions require plumbing rough-in, which we plan during the design phase. Connecting to your existing plumbing system is evaluated during the initial consultation.
In most cases, well-built additions increase property value. Bedrooms and bathrooms provide the strongest return. The key is quality construction that integrates with the existing home rather than looking like an afterthought.
