Garden-building foundations within SO43
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 measured approach in the heart of the Forest
Lyndhurst combines narrow historic plots, mature tree cover, Forest verges and drainage lines with larger edge-of-village gardens. Those conditions can influence access and finished height, but the chosen building's floor remains the starting point.
Craig will compare concrete, installed ground screws and raised timber without expecting a technical brief. Share the intended room, approximate dimensions and SO43 address to begin.

Genuine feedback on related building-base work
"Craig and his team have been fantastic. Had the team over twice now to help with our garden project and both times I've been super impressed with the work. The team are extremely hard working but most important to me is the quality of their workmanship. The fencing looks amazing and the cabin was spot on in terms of dimensions and perfectly level. I would highly recommend."

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 room needs an accurate foundation beneath insulation, thresholds, doors and glazing.
Suitable base options
Concrete
Continuous support for substantial rooms specified for a slab.
Ground screws and frame
Can suit compatible rooms where less excavation or quicker follow-on work is useful.
Raised timber
A practical route for selected timber rooms above manageable level changes.
Roots, valley water or a narrow High Street plot are considered only where they affect the chosen garden position.

Large timber buildings need the base to carry their wall rails and floor bearers in the right places.
Suitable base options
Concrete slab
Suitable where the building specification calls for a full rigid foundation.
Screw-supported frame
Can transfer loads from compatible bearers to defined supports.
Raised timber base
Useful for lighter cabins on uneven but suitable ground.
The supplier plan is useful before final set-out, while approximate dimensions are enough to ask for initial advice.

Equipment and use can change load, vibration and floor-stiffness requirements beneath a specialist room.
Suitable base options
Concrete base
Often the most direct foundation beneath heavier equipment.
Designed screw frame
Can work where the frame and floor account for intended loads.
Raised timber platform
Possible for lighter uses with appropriate support spacing.
Describe the equipment rather than calculating it yourself; Craig will identify what matters for the quote.

Pods commonly require support at chassis or bearer positions, with sensible ground clearance and access for installation.
Suitable base options
Ground screws and frame
Often efficient for defined supports and limited excavation.
Concrete foundation
Appropriate where the pod requires a continuous slab.
Raised timber base
Can suit compatible lightweight pods on a structural grid.
Overnight or letting use within the National Park can alter the planning route; foundation advice can proceed while that is checked.
Ask about this base →Local ground context
BGS Hampshire Basin coverage records laterally changing Palaeogene sands and clays, with peat and organic clay in some New Forest drainage lines. Tree cover and previous garden work add local uncertainty at the surface.
Those regional facts help prevent over-simple claims but do not diagnose a Lyndhurst garden. The room, footprint, visible site and known history drive the recommendation.
No ground report is needed before contact. Ordinary observations about water, roots or previous structures are a useful starting point.
Access handled with you
Lyndhurst can involve restricted central parking, narrow side access, open verges, roots and limited unloading space. Outlying SO43 properties may add gates, soft ground or longer drives.
A photo can answer the first access question, and Craig can arrange a visit where the route needs seeing. You do not need to organise the logistics before enquiring.

Useful local guidance
The complete garden building—not its foundation alone—determines whether permission is needed. Use, height, position, footprint and property rights all matter within the National Park.
The Lyndhurst, Swan Green and Bank appraisal describes conservation context around the High Street, cemetery and Goose Green. Apply it to the exact address without making the first foundation enquiry burdensome.
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 can help when selecting the building. Ask for the exact external footprint and any support plan before installation.
