Garden-building foundations across SO41
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 reliable foundation near the coast
A courtyard behind an older Lymington property, a Pennington garden and a more exposed coastal-edge plot can present different routes, levels and water considerations. The building itself may also require either continuous or framed support.
JustBases brings those details together without asking you to choose the construction system first. Give Craig the intended use, approximate size and SO41 postcode and we will explain the sensible options.

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 accurate base beneath its insulation, thresholds and glazing, with a sensible finished height.
Suitable base options
Concrete
Firm continuous support for substantial rooms designed for a slab.
Ground screws and frame
Can suit compatible buildings where access, excavation or programme favours point supports.
Raised timber
Useful for selected timber rooms where garden levels need to be bridged.
In lower Pennington or coastal-edge gardens, known water and exposure are worth mentioning; central courtyards may make the access route the deciding practical factor.

A large timber cabin should be supported beneath the perimeter and floor bearers shown by its manufacturer.
Suitable base options
Concrete slab
Appropriate when the cabin needs a continuous rigid foundation.
Screw-supported grid
Can align a timber or steel frame with approved bearer positions.
Raised timber platform
May suit lighter cabins on a modest fall with suitable floor support.
Send the model or base plan before final set-out if one exists. Approximate dimensions are enough to begin.

Specialist rooms may place extra demands on floor stiffness, loads, acoustic layers and service routes.
Suitable base options
Concrete foundation
Often ideal beneath heavy equipment and concentrated loads.
Designed screw frame
Can work where the frame and floor are sized for the intended room.
Raised timber base
Possible for lighter uses when spans and equipment positions are agreed.
Tell Craig what you plan to put inside; we will ask only for information that affects the foundation.

A pod's chassis or bearer arrangement dictates where support is needed and how the finished unit meets the garden.
Suitable base options
Ground screws and frame
Often suited to defined supports and low-excavation installation.
Concrete base
Useful where a manufacturer specifies a complete slab.
Raised timber platform
Can suit lighter compatible pods on a structural grid.
Sleeping or holiday-let use may alter the planning route, but you can discuss base options while confirming the proposal.
Ask about this base →Local ground context
Hampshire Basin geology around Lymington includes Palaeogene sand-and-clay units, plateau and river gravels and low-lying estuarine alluvium. Pennington and coastal plots can therefore present different water and exposure questions from higher inland gardens.
Garden construction, drainage and old hardstanding add further local variation. We use the geological context carefully while selecting the foundation from the actual room and site.
No ground report is expected before contact. Tell us about known winter water or previous work in ordinary terms and we will keep the advice proportionate.
Access handled with you
Central Lymington can mean restricted parking, narrow passages or rear courtyards, while larger Pennington and edge-of-town plots may have long garden routes and mature planting.
These are manageable quotation details. An optional photograph often establishes the route, and Craig can visit when access or level changes need a closer look.
Helpful if you have them—not required before you call:
Useful local guidance
New Forest District Council covers the town, with National Park land close by and boundary questions at some rural addresses. The complete building's use, height, size and position determine the permitted development position.
Lymington and Pennington plan evidence identifies three conservation areas and mapped flood risk. Those checks matter where they apply and can be made alongside the foundation 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 businesses provide useful local research while choosing the room or cabin. Ask for its outside footprint and floor-support requirements.
Timber-building range with a Lymington display site.
