What This Type of Project Covers

Room additions cover a wide range of projects that involve everything from adding a single bedroom to major kitchen expansions. At their core, room additions mean physically extending your home's footprint — either horizontally or vertically. This is not the same as remodeling, which stays inside the original layout.

These projects call for a coordinated effort that brings together architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes.
