What is the delivery lead time?

Currently the lead time is around 4 weeks.

What is included in the price?

All prices include delivery, installation, VAT and a 10 year manufacturer’s warranty.

What base do i need for my concrete shed?

You will need a 10cm (4”) thick, flat, level concrete base, 15cm (6”) longer and 15cm wider than the size of the building. We recommend that your base is slightly higher than the surrounding area in order to help keep to your shed dry. Slabs, Tarmac or Block Paving are not suitable bases for a concrete shed.

Are the concrete shed dimensions internal or external?

The dimensions given are external to the outside of the concrete panels. When measuring up, please allow for roof overhang and guttering. Internal shed dimensions are 6" (15cm) less than external.

What size vehicle will my concrete shed be delivered on?

Your building will be delivered on a large rigid truck or an articulated lorry. This is unloaded with a forklift and then the panels are transferred to a trolley, see below regarding access.

What kind of access do i need for delivery of my building?

As most concrete sheds are in back gardens, the installers will need to be able to wheel the concrete panels 2 at a time on a trolley via an unrestricted route from the delivery wagon to the concrete base. Small steps will need to be ramped and lawns will need to be boarded to facilitate delivery.

What guarnatee do i get with my building?

The concrete buildings carry a 10 year structural guarantee, the personnel doors and windows have a 2 year guarantee.

Do i need planning permission?

Very occasionally, planning permission is required. The Planning department of your local authority should be able to help you further with this; it may be worth looking on their website.

What are the payment terms for concrete sheds?

We take a 20% deposit if the concrete shed is ordered in person at our premises or over the phone. The balance is payable 14 days prior to installation. If ordered on-line please pay in full.

Can you do made to measure buildings?

Yes we can, within reason, as long as the building is square or rectangular. If you require a 9’ x 11’6” for example, please refer to the next standard size up – 10’ x 12’ for pricing. We cannot supply concrete buildings with walls that taper from front to back or that do not have 90 degree corners.
