Concrete Bases for Garden Rooms & Sheds in Epsom

If you’re planning to install a garden room, garden office, cabin or shed, the most important part of the project is the foundation.

At Epsom Fencing, we specialise in reinforced concrete bases for garden rooms and sheds in Epsom and surrounding Surrey areas. We build solid, level and long-lasting foundations designed to properly support modern garden buildings.

A poorly installed base can cause cracking, sinking, drainage problems and structural movement. We build your base correctly from the ground up to prevent future issues.

Why a Proper Concrete Base Is Essential

Modern garden rooms are much heavier than traditional sheds. Insulated walls, double glazing and rubber roofing systems require strong structural support.

A professionally installed reinforced concrete base:

• Prevents movement and sinking

• Supports heavy insulated structures

• Protects against moisture

• Keeps doors and windows aligned

• Increases the lifespan of your garden building

• Helps maintain manufacturer warranties

Many suppliers will not install their garden rooms unless the base is reinforced and perfectly level.

Frequently Asked Questions – Concrete Bases in Epsom

How thick should a concrete base be for a garden room?

For most garden rooms in Epsom, a reinforced concrete base is typically between 100mm and 150mm thick, depending on the size and weight of the structure. Larger insulated offices and log cabins may require deeper sub-base preparation and reinforcement.

We assess each project individually to ensure the correct specification.

---

Do I need planning permission for a concrete base?

In most cases, a concrete base for a garden room or shed does not require planning permission if it falls within permitted development rules. However, height, boundary distance and intended use of the building can affect this.

We are happy to advise during your free site visit.
