Quick Facts

CUBE – 20′ x 20′ Detached Two-Car Garage

The Exterior:

CUBE – 20′ x 20′ Detached Two-Car Garage

Designed as part of our 20′ x 20′ garage series, The Cube modern two-car garage blueprint is a modernist’s delight, pulling from the simplistic forms of modern architecture.

Wrapped in a vertical corrugated metal siding & free of any roof overhangs, The Cube detached two-car garage gives off a modern, industrial feel.

The fully glazed, dual storefront-style overhead garage doors allow plenty of light inside, while the commercial-style, wall-mounted halogen lights offer ample nighttime light onto the driveway and entrance doors.

The commercial-style steel entrance door looks right at home, and large window wall-style windows allow ample light into the space.

The Interior:

CUBE – 20′ x 20′ Detached Two-Car Garage

On the interior, you have a painted drywall finish with two parking stalls; each is measuring 18′-8″ deep x 9′-4″ wide.

Access to the garage comes from a dedicated garage entrance off a 36″ wide side entrance door or through the dual 8′ wide by 7′ tall rolling overhead garage doors.

The Cube 20′ x 20′ modern two-car garage blueprint has a finished floor-to-ceiling height of 9′-0″, thus leaving some room to amend the plans to an 8′ tall overhead door if you so choose.

Windows are placed at 42″ above the concrete floor, making a workbench or freezer can be made to fit in nicely beneath.

Ceiling-mounted compact fluorescent lights are typical inside, with several wall receptacles specified off of a 60 AMP electrical sub-panel.

  1. Rebecca S.

    Love the modern look from my kitchen window but I gave it a 4 star review because this plan should have a cheap unfinished interior option.

  2. Serge Z.

    We were please with the ease of customizing the plans. We removed a window, adjusted the door location and increased the ceiling height. Exactly what we envisioned.
