Build your Liverpool shed in seconds.

At Liverpool Sheds, wooden garden sheds start from £399 for a pent shed and £499 for an apex shed, with free delivery and installation across Merseyside included in the price. The final cost depends on the size, the timber treatment and any extras such as extra windows, a stronger floor or a shed base. Pressure treated sheds cost more than dip treated sheds but last much longer. Larger buildings such as workshops, summer houses and garden offices cost more again. Prices can be spread over 12 monthly payments with Klarna, and every price shown is the delivered and installed price.

The right shed size depends on what needs storing and how much room there is to move around inside. A 6×4 shed suits garden tools and a lawnmower, a 7×5 or 8×6 holds bikes as well as tools, and a 10×8 or 12×8 gives enough space for a workbench. A good rule is to go one size bigger than first planned, because most sheds fill up faster than expected. Measure the space and leave at least 30cm around the shed for access and re-treating. Narrow gardens often suit a shed with the door on the end rather than the front.

Most garden sheds in Liverpool do not need planning permission because they count as permitted development. To qualify, the shed must be in the back garden, single storey, no more than 2.5m high at the eaves, and no more than 2.5m tall overall if it sits within 2m of a boundary. Further from a boundary the limit is 4m for an apex roof and 3m for other roof types. All outbuildings together must not cover more than half the garden. Listed buildings, conservation areas and flats have different rules, so check with Liverpool City Council or the local council in Sefton, Knowsley, St Helens or Wirral if unsure.

Tongue and groove sheds are stronger and more weatherproof than overlap sheds. Each tongue and groove board slots tightly into the next, which stops wind and rain getting through and keeps the walls rigid. Overlap cladding uses thinner rough sawn boards laid over each other, which are cheaper but more likely to warp, split and let water in over time. Tongue and groove cladding also has a smoother finish that is easier to paint or treat. For a shed that gets used regularly or needs to keep tools and bikes dry, tongue and groove is the better long term choice.

A pressure treated shed lasts longer, while a dip treated shed costs less. Dip treatment coats the surface of the timber, so the shed needs a fresh coat of wood treatment every year or two to stay protected. Pressure treatment, also called tanalising, forces preservative deep into the wood, which protects it against rot for many years with very little upkeep. Pressure treated timber looks slightly green at first and weathers to a silvery brown. Liverpool Sheds backs its pressure treated sheds with a 10 year guarantee against rot, which makes them the better choice for exposed or coastal gardens.

Yes. Liverpool Sheds supplies and installs garden sheds across Liverpool and Merseyside, so a shed is supplied and fitted by the same company, with delivery and installation included free in the price. Every shed is built to order in a Liverpool workshop and put up by an in house installation team rather than a courier or subcontractor. Installation usually takes place within 7 to 14 days of ordering, on a day agreed by phone once the shed is ready. Most standard garden sheds are installed in a few hours. Areas covered include Liverpool, Sefton, Knowsley, St Helens, Halton and the Wirral.

A garden shed needs a firm, level and well drained base to keep it square and stop the floor rotting. The most common options are a concrete slab, paving slabs laid on a compacted sub base, or a plastic or timber grid base filled with gravel. The base should be slightly larger than the shed so rain runs away from the walls. A shed placed straight onto soil or uneven grass will soon twist, and the doors will stop closing properly. Liverpool Sheds can supply combi bases and bearers to suit the size of shed if a suitable base is not already in place.

A well built wooden garden shed usually lasts 15 to 20 years or more if it sits on a proper base and is looked after. Pressure treated sheds tend to last longest because the preservative goes right through the timber. Dip treated sheds can last well too, but only if they are re-treated every year or two. Thicker tongue and groove cladding, a solid floor and a good roof covering all add years to a shed's life. Keeping soil, plants and standing water away from the walls and checking the roof every autumn helps a shed cope with wet Merseyside winters.

An apex shed suits gardens with open space and anyone who wants headroom, while a pent shed suits tighter spots against a wall or fence. An apex roof has two slopes meeting at a central ridge, which gives the most height through the middle and room for high shelving. A pent roof slopes one way, so the shed sits lower and is less likely to tower over a fence or block a window. Pent sheds are usually a little cheaper than apex sheds of the same size. In small terraced yards and side returns, a pent shed is often the neater option.

Yes, an old shed can be dismantled and taken away when the new shed is installed. Liverpool Sheds offers an old shed removal service across Merseyside, so the old building comes down and is removed before the new one goes up in the same spot. This saves hiring a skip or making several trips to the tip. The old shed should be emptied beforehand. It also helps to mention the size of the old shed, and whether it sits on concrete, slabs or bare ground, when ordering so the right amount of time is allowed on the day.
