Garden-building foundations across PO16
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 sound base between town and coast
An established Fareham garden, a property near Wallington or Cams and a more exposed coastal plot may differ in water, ground, access and tree cover. The room itself may require either continuous concrete or planned frame supports.
JustBases compares the three systems without expecting you to decide first. Share the building type, approximate footprint and PO16 postcode and Craig will explain the practical choice.

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 below insulation, doors and glazing and a finished height suited to the plot.
Suitable base options
Concrete
Continuous support for rooms designed around a rigid slab.
Ground screws and frame
Can suit compatible rooms where access, excavation or programme favours point support.
Raised timber
Useful for selected timber rooms on modest garden falls.
Near creeks or lower ground, known water is worth sharing; on established residential plots, trees and side access may have more influence.

A larger timber cabin needs support under its wall rails and internal floor bearers.
Suitable base options
Concrete slab
Suitable where the building supplier requests continuous support.
Screw-supported grid
Can align an approved frame with the cabin bearer plan.
Raised timber platform
Practical for compatible cabins across uneven ground.
A final base plan helps before installation; approximate size is enough to ask Craig for advice.

Heavy equipment and acoustic or service requirements can change floor loads and stiffness.
Suitable base options
Concrete base
Often the straightforward foundation beneath heavy equipment.
Engineered screw frame
Can work where frame and floor account for expected loads.
Raised timber base
Possible for lighter specialist uses with suitable spans.
Describe the room equipment in plain language and we will identify any detail that affects the quote.

Pods need support at chassis or bearer positions and an installation method suited to the route and site.
Suitable base options
Ground screws and frame
Often suited to clear supports and reduced excavation.
Concrete foundation
Appropriate where the pod requires a full slab.
Raised timber platform
Can support compatible lightweight units.
Sleeping or letting use may alter planning and building requirements; foundation advice can continue while those are checked.
Ask about this base →Local ground context
Hampshire Basin records show Palaeogene clays and sands, river terraces and low-lying coastal or creek alluvium across the wider Fareham area. Wallington, Cams and coastal plots can therefore differ from higher gravelly ground.
Old services, trees, previous structures and garden drainage add further plot-level variation. The actual room and footprint guide our foundation comparison.
No ground report is needed before first contact. Share known water or previous work and we will keep any follow-up proportionate.
Access handled with you
Fareham access can involve narrow side passages and busy streets or wider established gardens containing protected trees and old services. Lower plots may also stay soft in wet weather.
An optional photograph helps plan materials and equipment. Craig can visit where the route or garden levels need confirming before quotation.

Useful local guidance
Whether a garden room is permitted development depends on use, height, position, footprint and the property's rights, not the foundation material.
Fareham Borough Council lists 13 conservation areas and provides a property map for trees, conservation and applications. Use it for the exact address while continuing the base enquiry.
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.
