Expanding Your Living Space Across the Treasure Valley

RJH Construction specializes in building high quality home additions that blend seamlessly with your existing structure while providing the extra room your family needs.

Custom Home Addition Design and Construction

Our team provides comprehensive expansion solutions in Nampa and Boise that range from modest bump outs to full scale room additions.

Structural Expansion

We manage the entire process of adding square footage to your home, including foundation work, framing, and roofing.

Seamless Architectural Integration

Our focus is on ensuring the new addition matches your home’s existing style, materials, and roofline for a cohesive look.

Multi-Purpose Room Additions

Whether you need a new home office, a primary suite, or a larger kitchen area, we design layouts that improve your home’s flow.

Custom Interior Finishes

From drywall and trim to flooring and lighting, we handle all the finishing touches required for a professional, move-in-ready space.

Code Compliant Construction

We ensure every addition meets local building codes and safety standards for structural integrity and energy efficiency.

Quality Foundations and Exterior Work

Because we have a strong background in masonry, we pay closer attention to the exterior elements and foundations that define a building's longevity.

Foundation and Flatwork

We ensure your new addition is built on a solid foundation, including custom concrete or masonry base work.

Exterior Masonry Accents

Enhance the look of your new addition with stone or brick veneers that provide curb appeal and durability.

Weatherproof Construction

Our building techniques include superior moisture barriers and insulation, keeping your new space comfortable in Idaho's seasonal climate.

Managing the Building Process

Beyond just the construction phase, we have the structural expertise to navigate the complexities of adding onto an existing home.

If your vision includes removing exterior walls to create an open transition between old and new or building up for a second-story expansion, we handle the entire project from start to finish. This includes site preparation, structural framing, and ensuring all electrical and plumbing systems are tied into your current home’s infrastructure. We take pride in a labor of love approach, making sure the hidden structural elements like joists, headers, and load-bearing transitions are built to last.

A Personalized Approach to Every Project

Our team oversees every home addition to ensure the craftsmanship meets our strict standards for quality and structural longevity.

We understand that a home addition is a major investment for your property in Nampa or Eagle, which is why we focus on clean job sites and clear communication throughout the build. Our goal is to provide a smooth expansion experience that results in a beautiful, highly functional space you will enjoy for years to come. By keeping our team small and focused, you receive the precise attention to detail that larger companies often overlook.
