Bellingham Home Builders and General Contractor, All Under One Roof
A1DesignBuild is one of the longest-serving home builders in Bellingham, WA. Since 1955 we've designed and built custom homes, remodels and ADUs for families across Whatcom County. Here's what makes us a little different: our architects, designers and builders are one team, in one building, usually sharing one pot of coffee. That means one point of contact, a budget you can trust, and a home that's comfortable, healthy and efficient from the first sketch to the day you move in.
