This custom prefab steel garage from Dongji House combines two connected modules to create a spacious 7 × 5 m parking and storage area. The UK project features a reinforced bottom frame, a raised pitched roof, an all-black exterior and a 3 m-wide electric roller shutter door. Dimensions, insulation, colors, doors, windows and electrical systems can all be customized for residential, commercial or workshop use.
Custom Prefabricated Steel Garage for Cars, Storage and Workshop Use
This prefabricated steel garage is designed for customers who need a secure, practical and customizable space for vehicle parking, equipment storage or workshop activities.
The model shown on this page was manufactured by Dongji House for a customer in the United Kingdom. Two prefabricated modules were connected to form a 7 × 5 m garage, providing more usable internal space than a standard single-module building.
To meet the requirements of garage use, the bottom structure was reinforced with additional steel supports. This provides a stronger base for vehicles, tools and storage equipment. A 3m-wide electric roller shutter door creates convenient access for cars, while a separate entrance door can be added for daily pedestrian access.
The garage is completed with a raised pitched roof. The roof structure adds approximately 0.5 m to the overall height and helps direct rainwater away from the building, making the design suitable for the wet climate of the United Kingdom.
The exterior of the UK model uses a complete black finish, giving the garage a simple and modern appearance that works well with residential gardens, private properties and commercial sites.
Rather than being limited to one fixed model, each garage can be manufactured according to the customer’s available land, vehicle dimensions and intended use. The overall size, structural reinforcement, wall insulation, roof design, roller shutter door, windows, electrical system and interior layout can all be adjusted before production.
Two-Module Combined Structure
The UK garage uses two connected prefabricated modules to create a wider internal area. The modular design also allows the overall length and width to be adjusted for different sites.
Reinforced Bottom Frame
Additional steel supports are installed in the bottom frame to improve the stability of the floor structure. The reinforcement design can be adjusted according to the intended load and final flooring system.
3 m Electric Roller Shutter Door
The wide electric roller shutter door provides convenient access for cars and equipment. Its width, height, color and operating method can be customized.
Raised Pitched Roof
The pitched roof is raised by approximately 0.5 m above the standard wall height. Its sloping surface improves rainwater drainage and gives the garage a more complete architectural appearance.
Optional Electrical System
Lighting, sockets, switches, wiring and distribution boxes can be installed during production. The UK model can be supplied with a CE-standard electrical configuration.
Flexible Doors and Windows
In addition to the main roller shutter door, the garage can be equipped with steel entrance doors, PVC windows, aluminum windows or ventilation openings.
