What We Do

Support built around real site conditions

Every SDU project starts with the existing home. We help homeowners understand the construction side of creating a secondary unit by focusing on the structural and access-related work that often needs to happen first. Our team supports projects involving basement entrances, egress windows, foundation wall openings, and concrete cutting so the space can move forward with confidence.
