Garden-building foundations across SP6
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
Build beside the Avon with confidence
Fordingbridge sits where chalk country, the Avon corridor and New Forest basin geology meet. A riverside garden, western downland plot and property east of the river should not receive the same automatic foundation advice.
JustBases begins with the room, not a soil label. Share the intended use, approximate footprint and SP6 postcode and Craig will compare concrete, ground screws and a raised timber platform.
What are you planning?
Three easy steps
Our questions stay practical and the agreed scope stays in writing.
Call, WhatsApp or use the form with the building type, rough size and postcode.
We compare suitable systems and arrange a visit when the river, slope or route makes it useful.
The footprint is set out and the base completed ready for the approved building.
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 continuous, rigid base for substantial buildings whose floor is designed to sit above concrete.

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 workspace needs a stable, square base coordinated with thresholds, glazing and an insulated floor.
Suitable base options
Concrete
Continuous support for buildings designed around a slab and full-area bearing.
Ground screws and frame
Useful for compatible rooms where reduced excavation, access or garden levels favour point supports.
Raised timber
Can suit selected timber rooms needing a level platform above a moderate fall.
Known Avon flooding or winter water belongs in the conversation, while higher western plots may instead need attention to slope and chalky ground.

A larger cabin needs support beneath its perimeter and internal bearers, set square for the wall system.
Suitable base options
Concrete slab
Suitable when a cabin supplier requires full, rigid support across the footprint.
Screw-supported frame
Can align with defined bearer lines through an approved structural grid.
Raised timber platform
Useful for compatible cabins on gardens where a framed solution handles the fall cleanly.
A supplier diagram is useful before set-out, but the model and dimensions are enough to begin a Fordingbridge quotation.

Heavy equipment, acoustic build-ups and services can make the room use important to the foundation choice.
Suitable base options
Concrete base
Often best for heavier equipment and a firm full-area floor.
Engineered screw frame
Possible when floor and frame account for the expected equipment loads.
Raised timber base
Can suit lighter specialist uses with appropriate spans and support points.
Describe the intended equipment and Craig will identify only the details that matter to the written price.

Pods commonly have defined chassis or bearer positions, making accurate support layout especially important.
Suitable base options
Ground screws and frame
Often well matched to clear support points and low-excavation installation on rural plots.
Concrete foundation
Appropriate where the manufacturer requires a slab or floor services are integrated.
Raised timber platform
Can support suitable lightweight pods with a compatible floor system.
For sleeping or commercial letting, planning and building requirements may change; base advice remains available while these are checked.
Ask about this base →Local ground context
The BGS Ringwood memoir describes chalk downland west of the Avon, Palaeogene sand-and-clay ground to the east, and terraces plus alluvium through the river corridor. This is a clear example of why the town name cannot specify a foundation.
Garden fill, former structures, drainage and local slopes add another layer of variation. We use known context to ask useful questions, then decide from the actual building and site.
No geological report is required before calling. Tell us what you already know about water, levels or previous work and we will keep the next step proportionate.
Access handled with you
Fordingbridge-area projects may involve older narrow plots, bridges and limited parking or longer lanes with gates, verges and overhead branches. The route can influence which materials and machinery are most practical.
An access photo is helpful but not a precondition of enquiry. Craig can arrange a visit where a rural route or garden fall needs to be understood before pricing.

Useful local guidance
New Forest District Council is the principal authority, while some eastern rural SP6 addresses fall within the New Forest National Park. The exact postcode confirms the correct planning route.
Fordingbridge has a conservation area, and permitted development depends on the whole building's use, size, height and position. These checks can run alongside a straightforward base quotation.
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 regional businesses are possible starting points for the room itself. Ask the supplier for the external footprint and support layout when available.
