Types of Additions We Build
Every addition starts with understanding how your family needs the space to function. Here are the most common projects we take on.
Primary Suite Additions
Ground-floor or second-story primary bedroom and bathroom additions with walk-in closets, en-suite baths, and private outdoor access.
Second-Story Builds
Full or partial second stories that double your living space. We engineer the existing structure to carry the load and match the roofline.
Sunrooms
Three-season and four-season sunrooms with insulated glass, radiant heat options, and seamless transitions from your main living areas.
In-Law Suites
Self-contained living quarters with private entry, kitchenette, bedroom, and accessible bathroom. Built for comfort and independence.
