Frequently Asked Questions
Got questions about room additions? We’ve got answers! Here are some of the most common inquiries we receive from homeowners looking to transform their spaces.
What types of room additions do you build?
We build a wide range of additions including bedrooms, offices, dens, sunrooms, bonus rooms, and even full in-law suites with kitchens and bathrooms. Every addition is designed to fit the layout, style, and function of your current home.
How long does a room addition take?
Most room addition construction projects in Brandon take 8 to 16 weeks depending on size, complexity, and weather conditions. Second-story additions or major structural changes may require more time. We provide a clear project timeline during the planning phase.
Do I need permits for a room addition?
Yes — room additions almost always require building permits, zoning approval, and in some cases, HOA approval. We handle the entire permitting process, including architectural drawings, city submissions, and inspections.
Can you match the existing exterior of my home?
Absolutely. One of our top priorities is ensuring your new addition blends seamlessly with your existing architecture. We match siding, roofing, trim, and windows so your addition doesn’t feel like an afterthought — it feels like it’s always been there.
Do you build second-story additions?
Yes — we design and construct second-story additions for homeowners looking to expand vertically. These projects require careful planning, but our structural and design team works together to ensure everything meets code, stays safe, and looks fantastic.
Can I live in my home during construction?
In most cases, yes. For additions that are built onto the back or side of your home, we can often section off the construction area. If the project involves major structural changes or affects essential rooms like your kitchen or bathroom, we’ll discuss temporary alternatives.
Do you offer other remodeling services?
Yes — we are a full-service design-build firm. In addition to room additions, we offer kitchen remodeling, bathroom remodeling, floor installation, lighting replacement, door installation, shelving installation, outlet installation, cook top upgrades, windows, and full home renovations throughout Tampa Bay and surrounding areas.
How do I get started on a home addition?
Start with a free consultation. We’ll assess your goals, budget, and timeline, then provide recommendations for the best path forward. With our custom services, strong client reviews, and transparent process, we’re confident you’ll love working with Coastal Haven.
