Garden-room foundations across Poole
Ground screws, concrete and raised timber-frame bases for garden rooms, offices, cabins and substantial garden buildings—with clear prices and a full 10-year guarantee.
Illustrative garden-room example
A straightforward start
A compact office in Parkstone, a larger cabin near Canford Heath or a studio in Hamworthy can each need a different foundation. JustBases installs concrete slabs, ground screws and raised timber bases across Poole, then explains which option makes sense for the building and garden.
You do not need to choose the foundation before contacting us. Tell us the building type, approximate size and postcode; a garden photograph is useful if it is easy to send, but it is not a condition of getting advice.
What are you planning?
Three easy steps
Getting a price should feel easy. Craig will ask the useful questions and arrange a visit only when seeing the garden would help.
Share what you want to build, the approximate footprint and your Poole postcode. That is enough to begin.
We listen, look at the site when useful and provide a clear written quotation for the agreed foundation.
The team marks out and installs the base ready for the garden-building installation or approved support frame to follow.
Choose the foundation, not the complication
You do not need to choose one now. We compare the building, garden and access, then explain the simplest suitable option.
A solid full-area slab for substantial garden rooms where a traditional concrete foundation suits the building and access.
From £695 for 8' × 6' 48 ft² / 4.46 m²
A lower-excavation option for many Poole gardens, particularly where a full concrete slab would create avoidable disruption or level changes.
Installed screws from £1,180 for 8' × 6'; frame quoted separately 48 ft² / 4.46 m²
A practical framed platform for sloping or uneven gardens where building up a deep concrete base would be unnecessary.
From £840 for 8' × 6' 48 ft² / 4.46 m²
Useful guide prices
These are current guide prices for standard installations. The written quotation confirms access, levels, preparation, ground conditions, support layout and any optional DPM or service conduit.

Match the base to the space
The building name is only the starting point. We also consider its footprint, support arrangement, intended use and the garden it needs to fit.
A year-round office or studio needs an accurately sized, level base so doors, glazing and the finished floor can be installed as intended.
Suitable base options
Concrete base
A strong choice for substantial, fully finished rooms when the building is designed around a full-area slab.
Ground screws and support frame
Useful when reducing excavation, avoiding concrete curing time or dealing with changing garden levels matters.
Raised timber base
Practical for suitable timber buildings on sloping or uneven gardens where a level framed platform is needed.
For established Poole gardens, we can compare a concrete slab with framed options that may reduce the amount of excavation and material movement through the property.

Larger timber buildings can suit concrete, ground screws or a raised frame. The building footprint and support arrangement guide the choice.
Suitable base options
Concrete base
Well suited to heavier cabins or buildings whose supplier specifies a continuous, rigid slab beneath the floor.
Ground screws and support frame
A good option when the cabin can sit on a planned timber or galvanised-steel support grid with less digging.
Raised timber base
Can create the level platform required by a timber building where the garden falls or access is restricted.
If the supplier has supplied a base plan, send it when convenient. If not, the building size and model are enough for an initial conversation.

Gyms, golf-simulator rooms and other specialist spaces can place different demands on the floor and services beneath it.
Suitable base options
Concrete base
Often the natural starting point for heavy gym equipment or spaces needing a firm full-area floor.
Ground screws and engineered frame
Can work when the building and frame are designed for the equipment loads and required floor stiffness.
Raised timber base
Possible for suitable specialist rooms when the support layout, spans and anticipated loads are agreed first.
Tell Craig about heavy equipment or planned service routes and we will include the relevant foundation details in the written quotation.
Ask about this base →
Garden pods, glamping pods and compact cabins need a foundation coordinated with their structure, intended use and site.
Suitable base options
Ground screws and support frame
Often practical where a pod has defined support points and the aim is to limit excavation and concrete use.
Concrete base
Suitable when the pod supplier requires a complete slab or the floor and services are designed around one.
Raised timber base
Can suit lighter structures on uneven ground when the supplier's support requirements are followed.
Where a pod is intended for sleeping, letting or self-contained accommodation, the use may change the planning and building requirements; the foundation can still be discussed while those details are confirmed.
Ask about this base →Local ground context
The British Geological Survey describes the Poole Formation as repeated sequences containing both sand and clay units. That regional picture is useful because it shows why it would be misleading to describe every Poole garden as simply sandy.
Topsoil, drainage, previous landscaping and local changes in level also affect the ground close to the surface. We consider the actual garden and proposed building rather than selecting a foundation from a postcode-wide assumption.
You do not need to arrange a soil report before calling. Start with the building size and location; we will explain if anything more is genuinely needed for the quotation.
Access handled with you
Poole includes compact urban plots, established suburban gardens and larger wooded properties. A side gate, longer route from the road, planting or a change in level may affect how materials and equipment reach the base area, but these are normal matters to discuss rather than reasons to delay an enquiry.
A quick photograph of the route can often answer the first access question. If a visit would be clearer, Craig can arrange one before the written price is confirmed.
Helpful if you have them—not required before you call:
Useful local guidance
The foundation material does not decide whether the complete garden room needs planning permission. The building's use, position, height, size and the property's status all matter. BCP Council is the local planning authority for Poole.
National outbuilding guidance includes limits and conditions, and it does not cover separate self-contained living accommodation. Poole also has conservation areas and protected trees at specific properties. These checks only matter where they apply, and you can still ask JustBases for foundation advice while the building details are being confirmed.
Planning information is a practical starting point, not legal or planning advice. Confirm the position for the exact property and building with the relevant authority.
Choosing the building
If you are still choosing the room itself, these independent local businesses are useful research starting points. Ask the supplier for the external footprint and any base requirements when available.
