Custom Steel & Garage Mezzanines — Call (480) 485-7989

Over-Garage Mezzanine Lounges, Offices & Loft Suites

The space above your garage doesn't have to be storage. Turn it into a room you actually use.

A garage ceiling is usually the tallest unused volume on a residential lot. DOM Contracting builds a steel mezzanine into that space to add a genuine second room — a lounge, a home office, or a fully finished loft suite — without expanding your home's footprint.

Three Ways to Use the Space

Over-Garage Mezzanine Options

Open Lounge

An open seating area with a TV wall and bar, comfortable underfoot with plywood or composite decking.

Home Office

An enclosed, insulated room with real HVAC and electrical for a genuine workspace.

Loft Suite

A fully code-compliant guest suite with plumbing, egress, and finished bath.

Stairs & Railings

Custom stairs and railings sized to your garage footprint and existing floor plan.

Planning It Right

Structural & Code Considerations

Each of the three uses above changes the structural and code requirements. A lounge can often stay open to the garage below with lighter code requirements; an office or loft suite needs to be a fully enclosed, insulated room with code-minimum ceiling height and, for a suite, proper egress and plumbing. We plan the structure around your intended use from day one — see our blog post on mezzanine design ideas for lounges, offices, and guest suites for the full breakdown of each option.

FAQ

Common Questions

The most common builds are an open lounge, an enclosed home office, or a fully finished guest suite. Each has different structural and code requirements — a lounge can often stay open to the garage below, while an office or guest suite needs to be a fully enclosed, insulated room with proper egress.
Yes. Any mezzanine addition requires PE-stamped structural engineering and local permitting, which DOM Contracting handles as part of every project.
It depends on the use. An open lounge needs less clearance than an enclosed office or guest suite, which requires code-minimum ceiling height on both the ground floor and the mezzanine level. We evaluate your existing garage's ceiling height before finalizing the design.
