A garden shed is a great option to add extra storage space in your garden. Lock away your lawnmower, tools, outdoor toys and furniture so it doesn’t get weather damaged or stolen. But how do you build a shed? We’ll go through a brief guide on building a shed using a flat packed one. Plan your shed base You must have a sturdy base for your shed, otherwise the frame won’t stand properly and could stop the door from opening. Decide whether you’re going to have: A concrete base laid on hardcore Concrete slabs on sharp sand Treated wood beams on hardcore or shingle An interlocking plastic system All bases should be laid on firm, level ground as far as possible. Treat wood with preservative To help your shed last as long as possible, you should coat all the wooden parts with timber preservative before you put it together. Put the shed floor together Some will need more assembly than others, but you need to make sure that the floor panel is attached to the joists; follow the manufacturer’s instructions for the correct spacing. Put up the shed walls Mark the centre point of each wall on its bottom edge, then do the same for the shed floor so you can line them up together. Stand the gable end on the base and line it up. Check that it’s vertical with a spirit level – you might need someone to support the panel while you do this. Use a temporary holding batten to keep it in place. Fix a side panel to the gable end panel with countersunk screws, then add the second side panel in the same way. Don’t attach the panels to the floor until you’ve fitted your shed roof. Fit the roof If the shed comes with a support bar, put this in position before you put the roof panels in. Nail the roof panels in place, ensuring there’s a parallel and equal overlap at each end. Roll out some roofing felt from front to back, leaving a 50mm overlap at each side. Secure it with clout-headed felt tacks at 100mm intervals. Apply mastic sealant to the outside corners, then fix each corner trim with 30mm nails. Add the fascias and finials, predrilling 2mm holes to avoid splitting the wood. Nail them through the felt into the shed using 40mm nails. Add the shed windows Slide each windowsill into the tongue and groove cut out, then put the window cover strip in position, fixing it to the vertical framing. From inside the shed, put the glazing sheets into the window rebates, making sure the bottom edge of the glazing sheets sit on the outside of the sill. Fix the window beading on the top and sides with 25mm nails. Fix the walls to the floor Before you do anything, make sure you check that the centre marks on the walls line up with the marks on the shed floor. Then fix the wall panels to the floor with 50mm screws, aligning them with the joists. And that’s it! But if you’re not confident in building a shed yourself, there are plenty of professionals available who will be happy to help.

Garden sheds are a critical aspect of any functional garden space. They can offer storage for cumbersome garden tools, as well as for other tools. A larger sized shed could even offer enough room for plant potting or a general workshop. Additionally, a sizeable shed could be used as an inside seating area. Garden sheds come in a huge variety of sizes and can be specified to your particular requirements, providing you with total control over the amount and placement of windows, type, size and location of door, and style of roof. Garden sheds generally come in one of three materials. Wooden sheds are the traditional style and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to neighbouring fences. Wooden sheds remain extremely popular, although they will demand maintenance by retreating or staining the wood to preserve the lifespan of the shed. Garden sheds are also made of metal, which is very durable and therefore great for storage of tools and other equipment. Metal sheds additionally require hardly any maintenance. The final material for garden sheds is plastic, which in modern examples is far more durable than might be expected. When contemplating a garden shed, it's important to make certain you pick one which will fit in your garden space. Garden sheds should be placed on a flat area, and will require a base to be built as a foundation. This base could be made from either concrete, paving, gravel or a floating wooden base, but will have to be the right size for your shed and able to support the weight of your shed when loaded.

FAQs

If you spend time in your shed, whether you use it as a summer house or an office, you’ll probably want a bit of insulation in there for when it starts to get chilly. There are different ways to insulate a shed, and some aren’t expensive at all. You just need to decide what the best way for you is. Bubble wrap If you don’t spend too much time in your shed, bubble wrap is an easy and cheap way to insulate your shed. Simply attach bubble wrap strips to the framing of the shed to create an air gap, then screw or nail a sheet of MDF over the top. Fibreglass wool Fibreglass wool is a good option if you want to insulate your shed further. Make sure you use safety equipment to protect your eyes, nose, mouth and hands when you’re handling it. Tack a breathable membrane to the inner walls of the shed, then place the fibreglass wool on top. Add a sheet of MDF or wood board, ensuring all the fibreglass is covered. Insulating shed windows and doors You'll often feel draughts through shed windows and doors, and these are easy to block up. You can use foam filler or liquid wool along the edges of the windows and gaps in the door frame. Let it dry out after you’ve applied it then cut off any excess. Insulate the floor If you’re building a new shed, you could fit some underfloor insulation to the grid of the shed base – it could help reduce up to 40% of heat lost through the shed floor. But if your shed’s already built, you can line the floor with a breathable membrane then lay a rug or piece of carpet down. The membrane underneath stops any damp or rot forming, so it’s best not to lay a rug straight down on the shed floor.

Yes, it is possible to insulate a shed. You might want to do this if you’re planning on working in it during the winter. A professional will be able to help you find an insulated shed or advise you on how to insulate a shed that you already have. Always seek professional advise first before attempting to do this yourself!

Yes, your shed does need a base. This is to give it a solid, level foundation. Open soil will not help with the longevity of the shed itself or the contents within. The best materials to use to make your shed base are concrete, natural stone or wood.
