Ground screws in Christchurch
A low-mess base from Highcliffe to the town centre
Ground screws form a precise support grid without excavating the entire building area. They can keep the foundation stage much tidier in Christchurch gardens and remove the delay of waiting for concrete to cure.

Your enquiry
Ground screw installation in Christchurch
Local knowledge, handled by us
Christchurch ground details are our job
Ground can change between the Avon and Stour valleys, the coast and higher neighbourhoods. That local context helps us ask sensible questions, but it should not make the enquiry harder for you.
We look at the chosen building and the actual garden, then explain the foundation recommendation clearly. A visit is arranged by us whenever it is the easiest next step.
What we check for you
- 1 We plan the supports around the building
- 2 We choose the installation approach

- 4 We deliver a laser-levelled grid

Larger framed buildings with a compatible support grid.
Decks

Transparent guide prices
Christchurch ground screw price guide
Guide prices for common garden-building sizes, based on a standard installation. The two options make it clear whether JustBases or another supplier is providing the frame.
| Building size | Installed ground screws Frame by others | Installed screws + timber frame |
|---|---|---|
| 8' x 6' 2.4m x 1.8m 48 ft² / 4.46 m² | £1,180 | £1,650 |
| 10' x 8' 3m x 2.4m 80 ft² / 7.43 m² | £1,280 | £1,750 |
| 12' x 10' 3.6m x 3m 120 ft² / 11.15 m² | £1,400 | £1,850 |

| 20' x 10' 6m x 3m 200 ft² / 18.58 m² | £1,600 | £2,450 |
These are guide prices for standard installations. Your free written quotation confirms the exact price for your building and garden, including any support frame supplied by JustBases. Larger or unusual foundations are priced individually.
A simpler way to build the base
Why choose ground screws instead of a dug base?
For many Christchurch gardens, ground screws mean less spoil, fewer bulk deliveries and a quicker handover to the building installer.
| Factor | Ground screw foundation | Excavated concrete or aggregate base |
|---|---|---|
| Excavation | Support points only | Broad footprint removal |
| Water context | Planned around the building and garden | Usually needs a prepared, drained base |
| Sloping plot | Can support a level frame | May need extra digging to create the level |
| Programme | No cure delay | Concrete curing required |
Craig will recommend ground screws only when they suit the garden and building. JustBases can explain other base types when needed.
Easy to arrange
Older side passages and compact gardens can still work
Ground screw installation removes many of the heavy material movements involved in a traditional dug base, which can help around Christchurch's older and more compact properties.
You can start without an access survey. Send a quick photo if easy, or let Craig arrange a look when that is more useful.

Helpful local information
Christchurch planning links without the jargon
Many domestic garden buildings use permitted development rights. The usual checks concern the finished building and property rather than the ground screw foundation by itself.
BCP Council offers local planning, conservation and flood information where relevant. These links can be checked alongside your quote request, not before it.
You do not need to settle every planning detail before speaking with us. The links are here if they help, and Craig is happy to explain which parts relate to the base.
