Commercial work is full-service custom construction for challenging, complex, and inventive projects. Offices and other business spaces are part of that, not a side note.
Restaurant customization sits in the same practice: a dining room, a service line, or a customer space that has to match how the business actually runs.
Houzz also lists kitchen and bath remodels, custom trim and woodwork, roofing, concrete and stonework, and painting among the services offered.
