Expand Your Living Space with THP Builders

The Design-Build Process for Additions

Expanding your Wilmette home requires a thoughtful balance of architectural integrity, modern functionality, and personal lifestyle needs. If you need more space for a growing family or entertaining guests—but want to remain in the comfort of your existing home—our design-build process begins with a thorough consultation to understand your vision, preferences, and budget.

Fred personally oversees every phase, from initial design concepts through the final finishes, ensuring each addition blends seamlessly with your home’s original character. Whether it’s a second-story expansion, sunroom, or additional living space, we carefully account for local building codes while delivering exceptional craftsmanship, structural excellence, and cohesive design that enhances both beauty and long-term value.
