Four practical base options

Levels matter in a hilltop town

Set the shed at the right height before work starts

Shaftesbury's slopes make finished floor height and garden access especially important. A base that is level but positioned too high or too low can create an awkward step, interfere with doors or demand unnecessary retaining work.

We agree the building footprint and finished level first, then compare concrete, paving, raised timber and ground screws for the individual plot.

Choosing the construction

A foundation that responds to the fall

The amount and direction of slope can change the most economical construction.

Concrete platform

Suitable for substantial buildings when excavation and edge levels remain practical.

Raised timber frame

Can form a level platform over a falling garden for an appropriate timber shed.

Ground-screw support

Considered where point supports and a frame suit both ground and building.

Three easy steps

From first call to a shed-ready base

You do not need to work out the construction first. Tell us about the shed and garden; we will explain the suitable choices and price the agreed work.

  1. 01

    Call, WhatsApp or send the form

    Share the shed size, your postcode and what you know about the proposed position. That is enough to begin.

  2. 02

    Discuss the base and price

    Craig listens, arranges a site visit when it would help and provides a clear written quotation for the agreed foundation.

  3. 03

    We install the level base

    The team marks out and installs the chosen base to the agreed footprint, ready for the shed installation to follow.

Four practical choices

Choose the base that suits the shed and garden

You do not need to choose before contacting us. We compare the building, access, levels and intended use, then explain the simplest suitable option.

Prepared poured concrete base for a garden building

Poured concrete

A full-area slab for heavy sheds, workshops and buildings whose supplier requires a rigid continuous base.

  • Installed to the agreed footprint and finished level
  • Useful for heavier equipment and substantial timber buildings
  • We confirm when the shed installation can safely follow

From £695 for 8' × 6' (48 ft² / 4.46 m²)

Raised timber frame base being installed for a garden building

Raised timber frame

A treated support frame for suitable sheds on uneven or sloping gardens where a level platform is needed.

  • Supported at planned positions rather than across the full footprint
  • Can reduce excavation where garden levels change
  • Built to suit the shed footprint and bearer arrangement

From £840 for 8' × 6' (48 ft² / 4.46 m²)

Level paving slab base prepared for a small garden building

Paving slab base

A neat, level surface for many smaller sheds when the building supplier accepts a slabbed foundation.

  • Individual slabs laid on a properly prepared sub-base
  • Practical for storage sheds and compact garden buildings
  • Base dimensions coordinated with the shed before installation

From £620 for 9' × 5' (45 ft² / 4.18 m²)

Ground screws supporting a level timber frame in a garden

Ground screws

Installed galvanised supports for a suitable timber or steel frame, often with less full-footprint excavation.

  • Purpose-made machinery and laser-controlled levels
  • No concrete curing delay after the installed supports are checked
  • Support frame supplied by JustBases or coordinated with others

Installed screws from £1,180 for 8' × 6' (48 ft² / 4.46 m²); frame quoted separately

Local ground context

Greensand, Gault and Chalk around Shaftesbury

The BGS district memoir records Upper Greensand, Gault and Chalk across the wider Shaftesbury landscape. Hill slopes, local deposits and previous landscaping mean conditions can change between nearby properties.

We assess the visible ground and levels at the proposed shed position rather than making a bearing claim from the town's geology.

  • Slope is measured where it affects the base
  • The finished shed threshold is considered
  • Ground type is not guessed from the address

Access handled with you

Steep streets, village lanes and garden steps

Material movement in Shaftesbury can involve stepped gardens or sloping paths; surrounding villages may add narrow lanes and longer unloading distances. The quote accounts for the real route.

A few photographs can show whether a visit is needed to measure the fall or plan unloading.

Helpful if you have them—not required before you call:

  • Photograph across the slope
  • Steps between road and garden
  • Approximate floor height required by the shed supplier

Useful local guidance

Shaftesbury planning and heritage

Shaftesbury's historic setting means conservation and listed-building considerations can matter at some addresses. For any shed, height, position and use remain central to the planning answer.

Dorset Council is the planning authority; check the exact property and complete building proposal.

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

Shed suppliers around Shaftesbury

Local made-to-measure options can be useful on constrained plots, but the base still needs an agreed external footprint.

These are independently researched links, not endorsements or paid relationships. Confirm the current range, delivery area and base requirements directly with the building supplier.

Service area
