Playhouse Bases & Foundations

A playhouse base should keep the structure stable and dry without creating awkward edges in a busy family garden.

What the foundation needs to do

Although a playhouse is often lighter than a full garden building, soft ground and makeshift supports can still allow it to rock or twist. The foundation also needs to sit comfortably within the surrounding play area.

We size the base to the playhouse floor plan and discuss how children will approach the doors and steps. Concrete, paving slabs, raised frames and ground screws can all have a place depending on the model and garden.

Options, assessed properly

Suitable foundation methods

The methods below are possibilities to assess—not interchangeable specifications. We match the foundation to the product, loads, support points, ground and access.

Paving slabs

Paving-slab base

Accurately laid slabs provide a firm, clean surface for many conventional playhouses and make the surrounding area easy to maintain.

Often worth considering for: Small and medium playhouses on reasonably level gardens

From £620 for 9' × 5' (45 ft² / 4.18 m²)

Timber frame

Raised timber frame

A raised structural frame can bridge slight level changes while supporting the floor bearers above damp ground.

Often worth considering for: Timber playhouses with a defined bearer layout

From £840 for 8' × 6' (48 ft² / 4.46 m²)

Ground screws

Ground screws and support frame

Ground screws may support a frame with limited excavation where the playhouse has suitable structural support points.

Often worth considering for: Sloping sites or established gardens where excavation would be disruptive

Installed screws from £1,180 for 8' × 6' (48 ft² / 4.46 m²); frame quoted separately

Concrete

Concrete foundation

A concrete pad can suit a substantial play structure or a supplier specification requiring full-area support.

Often worth considering for: Large playhouses and combined play buildings with heavier loads

From £695 for 8' × 6' (48 ft² / 4.46 m²)

Before installation

Dimensions, approvals and responsibilities

Measure any veranda, slide tower or external steps as well as the enclosed playhouse. These elements can change both the support layout and safe clearance around the base.

The complete structure may still be subject to planning considerations because of its height, position or raised platform. The supplier and local authority can advise on the proposal where needed.

JustBases quotes the agreed foundation and groundwork. Product installation, specialist connections, commissioning and third-party design remain outside our scope unless the written quotation expressly includes them.

Playhouse Foundations FAQs

A prepared base helps prevent rocking, uneven settlement and floor timbers sitting on wet soil, even when the playhouse itself is light.
