Start with what you want to build
The right foundation for your playhouse
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.
Stable support
The playhouse should not wobble when doors, ladders or verandas are used.
Explore the details →Tidy thresholds
Finished levels should avoid an unnecessarily abrupt edge beside the entrance.
Explore the details →Water run-off
The layout should not encourage puddles beneath the floor or around play routes.
Explore the details →Model-specific points
Verandas, towers and activity attachments may need supports beyond the main cabin footprint.

From first call to a finished foundation
Getting started is simple. We will guide you through the choices and explain any information needed before installation.
Talk through the options
We discuss the site and suitable foundations, identify any supplier information needed and provide a clear written quotation.
Install and hand over
Our team marks out and installs the agreed foundation, with the required checks before the next stage of your project.
Choose the foundation, not the complication
Foundation options for your playhouse
These are the methods worth assessing for this application. The structure, support plan and actual ground determine the right choice—not a one-size-fits-all specification.
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.
Worth considering for: Small and medium playhouses on reasonably level gardens
From £620 for 9' × 5' (45 ft² / 4.18 m²)
Ask about this option →
Raised timber
Raised timber frame
A raised structural frame can bridge slight level changes while supporting the floor bearers above damp ground.
Worth considering for: Timber playhouses with a defined bearer layout
From £840 for 8' × 6' (48 ft² / 4.46 m²)
Ask about this option →
Installed ground screws
Ground screws and support frame
Ground screws may support a frame with limited excavation where the playhouse has suitable structural support points.
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
Ask about this option →
Concrete
Concrete foundation
A concrete pad can suit a substantial play structure or a supplier specification requiring full-area support.
Worth considering for: Large playhouses and combined play buildings with heavier loads
From £795 for 8' × 6' (48 ft² / 4.46 m²)

Planned around its use
What matters for your playhouse
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.

Model-specific points
Verandas, towers and activity attachments may need supports beyond the main cabin footprint.
When the design and ground are suitable
Why consider ground screws?
Year-round flexibility
A screw-only foundation avoids pouring and curing concrete, reducing one source of weather-related delays. Unsafe access, flooding, frozen or unsuitable ground can still mean postponing installation.
Less digging and mess
Localised supports can reduce excavation and spoil compared with extensive concrete foundations. Clearance, pre-drilling, service trenches and machinery access may still disturb the site.
A lower-impact approach
Using less concrete and moving less spoil can reduce material use and transport. Retaining vegetation may benefit habitats, but trees and wildlife still need protection. Steel manufacture and the full project design matter to any carbon comparison.
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.
