A few useful things to know before you orderYour questions answered

Clear answers from the people who will be arranging your delivery and installation.Helpful advice on bases, planning, delivery and caring for your new building.

Will I need a base?

Yes. Your building needs a firm, flat and level base, correctly sized for the floor area. We can advise on the most suitable option and can quote for timber-frame or concrete bases where required.

What about planning permission?

Whether planning permission is needed depends on the building’s height, where it will sit and your property. Under permitted development rights, a building with a maximum overall height of 2.5m can often be positioned up to a boundary, subject to the usual conditions. If it is higher than 2.5m, it will normally need to be at least 2m from any boundary, such as a fence line. Please check the finished height of your chosen building or ask us for guidance. For the full rules, confirm with your local council or visit Planning permission: when you need it – GOV.UK.

When can my building be delivered?

Lead times vary by product, specification and season. We will confirm the current estimated lead time when you place your order, then keep you updated as your building progresses.

What cover is included?

Warranty terms vary between ranges and manufacturers. We will confirm the exact cover for your chosen building before you order, along with any care requirements that help protect it for years to come.

Can I see buildings before deciding?

Of course. You are welcome to visit us at Highdown Garden Centre in Angmering or Squire’s Garden Centre in Washington to view selected buildings and talk through your requirements.
