Project Spotlight: Garage Addition Before-and-After

Completed on time in just five months for a family of four, this full home renovation included two major additions that completely transformed the layout and functionality of the home.

One of the standout features is a new two-car garage addition on the left side of the home, with two spacious bedrooms above, perfect for growing kids or guests. The project included updated siding, roofing, and gutters to refresh the exterior and create a cohesive, modern look.

This renovation not only expanded the home’s footprint but also redefined how it supports the family’s lifestyle, creating space to live, grow, and relax for years to come.
