Home Additions Tampa Bay
Master suite additions, mother-in-law suites, second-story builds, sunrooms, and garage conversions across Tampa Bay. Designed to look like they were always there — not bolted on.

The mark of a great home addition is that nobody can tell where the original house ends and the new build begins. The roofline matches. The exterior trim picks up the existing reveal. The interior floors continue without a transition strip. The drywall textures line up. None of that happens by accident — it happens because the addition was designed and built by the same people who treated "match existing" as a non-negotiable spec, not a nice-to-have.
Taurus Builders designs and builds home additions across Tampa Bay for every common scope. Master suite additions on the rear of single-story homes, often paired with a primary bath build. Mother-in-law suites (ADUs) for multi-generational families or income-producing rentals, where Tampa zoning allows. Second-story additions for clients who've outgrown their footprint and don't want to move out of South Tampa or Hyde Park. Sunroom enclosures for Florida rooms that aren't pulling their weight. Garage conversions that add usable square footage without adding to the foundation.
Whatever the scope, the first step is the same: a feasibility memo telling you what your lot and zoning actually allow before you spend a dollar on design.
Matched to the original. Engineered for the future.
A home addition isn't just new construction — it's new construction welded onto old. The continuous load path matters. The roofline tie-in matters. The floor elevation matters. None of these are details you can fix at finish.
Every Taurus addition is engineered to current Florida Building Code, tied into the existing structure with continuous load-path framing, and detailed at the join so the addition reads as original — not bolted on.
Seven phases. Match every detail.
