Room Additions in Indianapolis, IN

Full-Service Room Addition Contractor

A room addition is one of the most complex home improvement projects you can undertake — and one of the most rewarding. Whether you need a new bedroom for a growing family, a dedicated home office, a sunroom to enjoy Indiana's warmer months, or an in-law suite for aging parents, Bryant & Son delivers additions that look and feel like they were always part of your home.

What sets us apart from other Indianapolis addition contractors is simple: we handle every trade in-house. A room addition involves framing, electrical, insulation, drywall, painting, flooring, and often roofing and exterior work. With most contractors, that means coordinating 4–5 different companies, managing 4–5 different schedules, and hoping they all communicate with each other. With Bryant & Son, it's one team, one schedule, one point of contact.

We build bedroom additions, sunroom additions, second-story additions, garage conversions, in-law suites, and home office additions. We handle everything from the foundation and framing to the final coat of paint — including all electrical, drywall, insulation, roofing tie-ins, and exterior work to match your existing home.

Every addition we build is designed to match the existing architecture of your home. We pay careful attention to rooflines, exterior materials, window styles, and interior finishes so the new space feels cohesive, not tacked on.

Site Evaluation & Design

We evaluate your property, discuss your vision, and work with structural engineers as needed to develop a plan that works with your home's existing structure and your lot.

Permits & Engineering

We handle all permit applications and coordinate structural engineering documentation. Room additions require building permits — we manage the entire process.

Foundation & Framing

We prepare the foundation, frame the new space, and tie into the existing structure. Our framing crew ensures the addition is square, level, and built to last.

Mechanical, Drywall & Finishes

Our in-house team handles electrical, insulation, drywall, painting, flooring, and trim — all coordinated by your dedicated project manager.

Exterior Tie-In & Final Walkthrough

We match the exterior siding, roofing, and trim to your existing home. Final walkthrough ensures every detail meets our standards and yours.

Framing, electrical, drywall, painting, flooring, roofing tie-in — all handled in-house. No subcontractor juggling. One project manager coordinates everything.

We design every addition to match your existing home's architecture — rooflines, exterior materials, window styles, and interior finishes all align so the new space feels original.

We handle all permit applications, structural engineering coordination, and inspections. You never have to call the building department.
