The client sought to transform the unused space beneath their house into a functional living area, prompting a subfloor development that optimizes their home's potential. We designed a new slab foundation and constructed walling to create a cohesive, private space. Access is enhanced with the addition of stylish stairs leading down to the newly developed area, which now features a modern ensuite. This innovative project not only maximizes the available space but also elevates the home's overall functionality and appeal, making it a valuable extension for family living or guest accommodations.
