Custom Prefab Garage Built for a Homeowner in the UK
When people think about prefab buildings, they often imagine temporary structures. However, for many homeowners, a customized prefab garage offers a practical and long-lasting way to maximize unused outdoor space.
This project was developed for a customer in the United Kingdom, who wanted to transform an unused area beside his home into a secure garage and storage building.
The steel structure has now been erected, marking the first stage of the installation process.
Instead of allowing the land to remain unused and overgrown with weeds, the customer decided to invest in a customized prefab garage that would provide extra storage space while complementing the appearance of his property.

Why the Customer Chose Dongji House
The customer first discovered Suzhou Dongji House through our Alibaba store(https://dongjihouse.en.alibaba.com/).
During his supplier evaluation, he compared several manufacturers before contacting our team.
What impressed him most was not only our competitive pricing, but also our quick response time and our willingness to customize the building according to his actual requirements.
Rather than offering a standard garage, our engineers discussed every detail with the customer and proposed a solution tailored specifically to his site conditions and intended use.
This personalized approach ultimately led him to choose Dongji House as his prefab garage supplier.

Turning an Unused Space into a Functional Garage
Before construction, the area beside the customer's house had been left unused for years.
As his family accumulated more tools, equipment, and seasonal items, indoor storage gradually became insufficient.
Instead of building a traditional masonry garage—which would require longer construction time and higher labor costs—the customer selected a prefabricated steel garage that could be manufactured in advance and assembled efficiently on site.
The result is a clean, modern structure that fits naturally beside the existing house while making full use of previously wasted space.
Designed for the UK's Wet Climate
One of the biggest considerations during the design stage was the UK's rainy weather.
Rather than placing the garage directly on natural ground, the customer first poured a level concrete foundation.
He also installed a waterproof membrane beneath the structure.
This additional layer helps reduce ground moisture from reaching the steel frame, lowering the risk of corrosion underneath the building and improving long-term durability.
Although simple, this is an excellent practice for prefab garages installed in humid environments.

Why We Extended the Roof by 100 mm
A standard pitched roof already provides effective rainwater drainage.
However, this customer requested one additional improvement.
The roof was extended approximately 100 mm beyond the wall panels.
This small modification produces significant long-term benefits.
Instead of rainwater running directly down the exterior walls, the water falls clear of the building and onto the ground.
Benefits include:
Sometimes the smallest design changes make the biggest difference in long-term building performance.
Electric Roller Door for Everyday Convenience
The customer wanted quick and convenient vehicle access.
Instead of a traditional swing door, we installed a 5-meter-wide electric roller shutter door.
The system is connected to a CE-certified electrical system and can be operated using a remote control.
Advantages include:
Why Cement Fiber Board Was Selected for the Floor
To improve load-bearing performance, the customer chose cement fiber board for the interior floor system.
Compared with conventional wood flooring, cement fiber board provides several advantages:
These characteristics make it particularly suitable for garages, workshops, and storage buildings where heavy equipment or vehicles may be placed.
