Interior renovations and additions allow homeowners to adapt their living spaces as needs change—without leaving the home or neighborhood they love. These projects range from structural layout changes to full expansions that add livable square footage. Successful interior renovation work requires a deep understanding of construction systems, structural integrity, finish coordination, and long-term durability.

This page outlines the full scope of interior renovation and addition services available, including wall removal, open-concept conversions, basement finishing, room additions, ADUs, garage conversions, and detailed finish carpentry.

Wall Removal & Open-Concept Conversions

One of the most common interior renovation requests is opening up closed or compartmentalized floor plans. Wall removal and open-concept conversions can dramatically improve natural light, flow, and functionality within a home—but they must be done correctly to preserve structural integrity.

Summit provides professional wall removal services, including load-bearing wall modifications that require careful planning and engineering coordination. These projects often involve reworking framing, rerouting utilities, and integrating new structural supports.

Open-concept renovations are especially popular in older homes throughout Coeur d’Alene and Hayden, where original layouts may no longer match modern living preferences.

Wall removal and open-concept services include:

  • Non-load-bearing wall removal

  • Load-bearing wall removal with proper structural support

  • Open-concept kitchen, dining, and living area conversions

  • Beam installation and framing modifications

  • Utility relocation as required

Basement Finishing & Living Space Updates

Basements offer some of the greatest opportunities to increase usable square footage within an existing home. Basement finishing projects transform unfinished or underutilized lower levels into comfortable, functional living spaces.

Summit provides complete basement renovation services designed to address moisture control,

insulation, layout efficiency, and finish quality.

Room Additions

Cabinetry, countertops, and tile play a major role in both the appearance and function of

kitchens and bathrooms. These elements must be installed precisely and coordinated with surrounding finishes and mechanical systems.

opportunities, or multi-generational households. These projects require careful planning to
