Custom Home Remodeling on Mercer Island, WA

Thoughtful remodeling on Mercer Island should do more than update finishes. It should improve how the home functions, how spaces connect, and how the interior relates to the architecture, natural light, and surrounding property.

IDA Design & Build provides whole-home remodeling, kitchen and bathroom renovations, home additions, and interior design for Mercer Island homeowners. Our design-build approach keeps planning, materials, project management, and construction connected through one experienced team.

A More Cohesive Approach to Remodeling
Many Mercer Island homes have strong architecture, established landscaping, and valuable locations, but the interiors may no longer support the way the household lives today.
A renovation may begin with a kitchen that feels separated from the main living areas, a primary suite that needs better functionality, or several rooms that have been updated at different times without a consistent design direction.

Whole-home remodeling creates an opportunity to look at these spaces together. Layout, cabinetry, flooring, lighting, materials, storage, and architectural details can be coordinated as one connected design rather than treated as separate projects.

We begin with the existing home and determine where changes can make the greatest difference in comfort, flow, functionality, and long-term use.

Our Design-Build Process
Consultation
We begin by reviewing the existing home, your priorities, design goals, and the areas you want to transform.
Planning & Design
We develop layouts and coordinate cabinetry, flooring, tile, lighting, fixtures, materials, and other important architectural and interior details.
Construction
Our project management and construction teams coordinate the renovation according to the approved design and project scope.
Final Details
As construction approaches completion, we review the finished spaces and address remaining details before the final walkthrough.

Remodeling Homes Across Mercer Island

Mercer Island includes a diverse mix of mid-century homes, traditional residences, newer construction, and waterfront properties. Each type of home brings different opportunities and constraints when planning a renovation.
Some projects focus on opening the main living areas and improving the relationship between the kitchen, dining room, and family spaces. Others involve complete primary-suite renovations, custom cabinetry, updated finishes, or larger whole-home transformations.
Homes with lake views, sloped sites, mature trees, or established landscaping may also require greater attention to windows, exterior openings, additions, drainage, access, and the relationship between the home and the surrounding property.
Our approach starts with the existing architecture, layout, natural light, views, and site conditions before major design decisions are made.

Serving homeowners throughout Mercer Island, including North Mercer, East Mercer, South Mercer, West Mercer, and surrounding neighborhoods.

Structural Remodeling & Permit Planning
Major renovations can involve structural changes, additions, plumbing, mechanical systems, electrical work, and site conditions that should be evaluated early in the design process.
Structural Remodeling

Opening living spaces, creating larger wall openings, modifying roof structures, or reconfiguring major areas of the home can affect framing, beams, posts, and lateral-resistance systems.

Reviewing these conditions early helps coordinate design decisions, engineering requirements, and construction scope before major work begins.

Permits & Site Conditions

Mercer Island distinguishes between structural and non-structural interior remodels, and additions have separate permit requirements.

Depending on the property and project scope, additional documentation may also be required for geologically hazardous areas, critical areas, stormwater review, structural calculations, utilities, or work near protected trees.
