In-Law Suite Additions

In-Law & Primary Suite Additions (And Remodels)

Adding an in-law suite or upgrading your primary suite can greatly enhance your home’s functionality, comfort, and value. In-law suites are ideal for multigenerational living, offering privacy and independence for aging parents, adult children, or frequent guests. They also future-proof your home for changing family needs.

Upgrading your primary suite allows you to create a personal retreat with modern amenities like spa-like bathrooms or walk-in closets, adding both comfort and style. Whether accommodating family, improving convenience, or increasing home value, these additions provide practical, long-term benefits.

Where to Start

Planning a primary or in-law suite remodel begins with understanding your needs and goals. Think about who will use the space, key features like private entrances or bathrooms, and how it integrates with your home’s layout. Budgeting and permits are also critical steps. 

Working with a design professional, like the experts at 121 Design and Build, ensures a seamless process, from creating a functional, personalized design to managing construction.

Our experience helps you maximize comfort, style, and value, turning your vision into reality while avoiding common pitfalls. Start by consulting with our team to explore ideas and develop a plan tailored to your lifestyle.
