From framing to the last tile in your new shower, our crew builds each part of the suite to last and to look finished.
We set a realistic build schedule for your St. Petersburg addition, keep the site moving each workday, and tell you early if anything shifts.
Less overhead means your budget goes into the suite itself, so you get premium materials and skilled work without paying for a large company's office.
You deal directly with the local crew building your suite, not a call center, so questions get answered by people who know your project.
Your estimate spells out the bedroom, bath, closet and finish work line by line, so you know what you are paying for before we start.
Our Florida license and insurance protect you during the build, and our workmanship guarantee on the finished suite gives you real peace of mind.

Get My Free Estimate TodayFat Finger Construction builds master suite additions in St. Petersburg, FL for homeowners who love their neighborhood but have outgrown their bedroom. A master suite addition puts a new primary bedroom, a private bathroom and a walk-in closet under one roofline, planned together so the rooms flow and the new space feels like it was always part of the house. We handle the architectural plans, permits and zoning, the framing and roof tie-in, and the bath and finish work, so one team is responsible from start to finish.
St. Petersburg has a wide mix of homes, from Historic Kenwood bungalows and Old Northeast houses near Tampa Bay to mid-century block ranches off 34th Street and 4th Street N. Each one calls for a slightly different approach to rooflines, wall materials and window placement, and we match the addition to what is already there. Our Gulf Coast climate matters too. Heat, humidity, salt air near the water and heavy summer storms are hard on new construction, so we choose materials and details with Florida weather in mind and we go over impact-rated choices for the new windows and doors during planning. The result is a suite built to stay comfortable through every season.

The first step for every master suite addition we take on in St. Petersburg is a free in-home estimate. During that visit we look at your lot, your current floor plan and how you live, then give you honest, itemized pricing. Once you approve the plan, we keep the schedule disciplined and the job site tidy, and you can reach the people doing the work directly instead of passing messages through a sales office. Because we run lean, you get the quality of a large remodeling firm at a fair price, and you know the full cost before construction begins.
