Illustrative garden-room example
Make the most of the garden
From a compact office behind a terrace to a large studio in a wooded suburban garden, Bournemouth projects can differ sharply in access, level and ground. A base should respond to those differences without turning the quotation into an engineering exercise for the customer.
JustBases installs concrete slabs, ground screws and raised timber foundations. Give Craig the building type, approximate footprint and Bournemouth postcode and we will explain the practical routes in straightforward terms.

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 frequently used room needs an accurately sized base beneath its insulated floor, glazing and doors.
Suitable base options
Concrete slab
Reliable continuous bearing for buildings whose floor specification expects a full foundation.
Ground screws and frame
A strong option for compatible structures where access, excavation or programme favours point support.
Raised timber platform
Can level suitable timber rooms without building a deep concrete edge on a sloping garden.
In tighter Bournemouth plots, the route through or beside the property can be as influential as the room size, so we compare methods with both in mind.

Large timber buildings require support where their wall rails and floor bearers actually carry load.
Suitable base options
Concrete
Suitable for heavier cabins or suppliers requiring a continuous rigid slab.
Screw-supported frame
Can match a defined bearer arrangement through a planned timber or steel grid.
Raised timber
Useful for compatible cabins where a framed foundation addresses changing levels efficiently.
If you have the supplier's floor diagram, send it before final set-out. It is not needed to begin the price conversation.

Weights, movement and acoustic or service requirements can make a specialist room's foundation different from a standard office.
Suitable base options
Concrete foundation
Often preferable for heavy equipment and a rigid full-area finished floor.
Engineered screw frame
Can work where the building and support grid are designed for the expected point loads.
Raised timber base
Possible for suitable lighter uses with agreed joist spans and equipment positions.
Tell Craig the intended use and any heavy items; we will translate that into relevant foundation questions without adding unnecessary complexity.

Pod floors and chassis commonly have specific support points that should dictate the foundation layout.
Suitable base options
Ground screws and frame
Often effective for pods with clear supports and gardens where spoil and access should be minimised.
Concrete slab
Appropriate where the pod supplier wants a full foundation or floor-level service entries.
Raised timber platform
Can support suitable lighter units above a modest fall or uneven garden surface.
Use for sleeping, letting or independent accommodation can change permissions; base advice remains available while those details are checked.
Ask about this base →Local ground context
BGS sheet 329 describes a varied Palaeogene sequence beneath Bournemouth, including Branksome Sand and Poole Formation sand-and-clay units, alongside terrace, head and made-ground deposits. A sandy-looking topsoil is not a reliable town-wide foundation specification.
Urban redevelopment, old outbuildings, retaining work and landscaping can alter the near surface within one street. JustBases uses the site information to select between three systems rather than assuming uniform coastal ground.
You do not need to investigate the soil before contacting us. Begin with the room and postcode; anything more is requested only if it will genuinely affect the quotation.
Access handled with you
Bournemouth includes narrow side passages, through-house routes, rear access lanes and gardens dropping away from street level. Other neighbourhoods provide wide drives but have mature planting or protected trees around the proposed building.
None of this needs to be solved before you ask for a quote. An optional photograph helps us compare material routes and equipment, and Craig can visit when levels or access need a closer look.
Helpful if you have them—not required before you call:
Useful local guidance
BCP Council is the planning authority. National outbuilding allowances contain limits on use, height, position and coverage, and some properties have reduced or removed permitted development rights.
Bournemouth has numerous conservation areas and address-specific protected trees. Those records are valuable for the exact proposal, but they do not make foundation advice difficult or mean every garden room needs permission.
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
These nearby companies are useful for comparing buildings and specifications. Once you have a model, request its exact outside footprint and base requirement.
