Modular Garden Rooms

Do you need a durable, low-maintenance outdoor space?

Whether it is to store tools, set up a workshop, or create a multi-functional space that can be used all year round, traditional wooden structures are often exposed to corrosion, pests and fire hazards.

SteelPRO PEB’s modular garden house adopts an all-steel structure design and focuses on providing simple and reliable solutions:

No maintenance required: galvanized steel is rust-proof and insect-proof, with a service life of up to 30 years.
Quick construction: components are prefabricated in the factory and can be assembled on site with only basic tools.
Flexible adaptation: pre-buried water and electricity pipeline interfaces, convenient for later access to basic functions.

We do not do complex designs and additional services, but only focus on one thing: using cost-effective steel structures to create a practical space for you that is “ready to use after installation, worry-free for ten years.

What Makes Our Modular Garden Rooms Stand Out?

Many garden rooms on the market use traditional wooden or lightweight structures, but our Modular Garden Rooms are built with high-strength steel frames and prefabricated modular designs, ensuring superior durability, stability, and customization options. Designed to withstand various climate conditions, our garden rooms provide a long-lasting and versatile space for different needs.

1. Fully galvanized steel structure frame

90% of the garden houses on the market use wood or light aluminum. We insist on using 1.2mm galvanized steel plates, which have a compressive strength that is 3 times higher and are not afraid of extreme weather (can bear 500kg/㎡ snow load).

Completely solve the rot and insect problems of wooden structures, 30 years of maintenance-free, and long-term use costs are reduced by 60%.

2. High-efficiency heat insulation, suitable for all seasons

80mm wall = outer layer of galvanized steel plate + middle XPS insulation layer + inner layer of fireproof gypsum board (not the single-layer iron sheet on the market).

There is no condensation water when the temperature difference between the inside and outside is 20℃, which is suitable for use in all seasons, and the energy loss is reduced by 55% compared with the single-layer structure.

Optional double-layer or triple-layer low-e glass can improve thermal insulation and reduce noise interference.

3. Prefabricated modular design, faster and more economical installation

Factory prefabrication, reducing construction time: Our Modular Garden Room adopts modular production, all components are processed in the factory, and only simple assembly is required, which saves more than 50% of construction time compared with traditional brick and wood buildings.

Movable and expandable: If there is a greater demand for space in the future, our garden room can be modularly spliced to easily expand the usable area to meet changing needs.

Adapt to different terrains, low foundation requirements: It can be quickly installed on different ground such as grass, concrete, and wooden platforms, without the need for large-scale civil engineering.

4. Environmental protection and energy saving, reducing long-term use costs

Optional solar energy system, green energy solution: Supports the installation of solar panels, which can provide independent power supply for the garden room and reduce long-term electricity costs.

Low-carbon materials, reducing environmental impact: Our building materials meet sustainable development standards, are more environmentally friendly and durable, and do not require frequent replacement and maintenance like wooden buildings.

High efficiency and energy saving, reducing operating costs: Insulation materials + efficient ventilation design help save air conditioning and heating energy consumption, allowing you to use it comfortably all year round.
