A compact 12×25 metal garage designed to add secure storage and practical workspace without overwhelming a residential property.
This is a pre-designed starting concept. Final colors, dimensions, door clearances, engineering, certification, foundation requirements, availability and pricing must be confirmed for the installation location. Landscaping and surrounding property shown in the image are for visualization only. HOA and local approval are not guaranteed.
Design overview
A Compact Garage That Fits Residential Properties
The Single-Bay Vault offers meaningful enclosed storage and workspace in a 12′ × 25′ footprint. Its compact scale may fit beside or behind many homes more easily than a large detached shop, subject to property setbacks, easements, HOA or architectural-review rules, access and local building requirements.

Key Features
Garage, Workshop and Backyard Studio Possibilities
This versatile 12×25 footprint can adapt to a variety of property needs.
Secure residential garage storage
The enclosed shell can support compatible lawn equipment, motorcycles, recreational gear, household overflow storage or a compact vehicle after actual dimensions are compared with the 6′ × 7′ door and usable interior clearances.
Compact home workshop
A 300-square-foot footprint can provide room for tools, workbenches, woodworking or residential maintenance projects while remaining more manageable than a large detached shop.
Hobby, craft or she-shed space
The building can be planned as a personal retreat, hobby room or craft space. The base shell is not represented as conditioned or finished; electrical, insulation, interior finishes, HVAC, plumbing and code requirements depend on the intended use and final scope.
Finished backyard studio concept
With separately scoped improvements and local approval, the shell may be a starting point for a backyard studio concept. Zoning, setbacks, occupancy, utilities, egress, permits and HOA approval must be evaluated for the property.
Practical layout planning
Practical Single-Bay Storage with Separate Walk-In Access
A dedicated overhead bay supports compatible equipment, recreational gear or a compact vehicle, while the personnel door allows everyday access without opening the garage door. Fit is never assumed from a vehicle class or name.
- Compare exact vehicle width, height and length
- Account for mirrors, racks and accessories
- Confirm usable 6′ × 7′ door clearance
- Plan workbench and equipment circulation
- Use the walk-in door for routine access
- Keep the overhead bay clear for larger items
