Question 1

How to build a shed base?

Accepted Answer

You need a firm, level base for your shed to ensure that it stays structurally sound – without one, doors will sag, walls will lean and it won’t last you as long. But how do you build a shed base and what should you make it from? Timber shed bases A timber shed base is made from pressure-treated timber and has metal spikes that you hammer into the ground to keep it in place. You can often buy them with your shed installation kit, but they also come separately, often in 6x4 or 7x5 sizes. To build a timber shed base, you’ll drill holes then fit screws in the timber until the entire frame is built. Remember to check it’s square, then fix L-shaped feet to the inside of the frame. If you’re putting your shed on a hard surface like concrete, this is all you need to do. If you’re putting the base on soft ground, hammer in spikes at each corner until they’re level with the top of the base, then secure the spikes to the base with screws. Then you can position the shed floor onto the base. How to build a plastic shed base A plastic shed base is a simple and quick way to build a shed base. You can lay it on level concrete or paving slabs, but adding sharp sand on top will help keep it more secure. They come in a kit containing plastic grids. To build your plastic base, first measure out the site and hammer a peg into each corner and tie with string or builder’s line. Make it slightly larger than the shed base to help with drainage. Then cut into the lawn and remove the turf, making sure it’s level. Lay down a membrane sheet and weigh it down if it’s windy. Then lay out the number of plastic grids you need, then remove the locking pins and clip all the grids together. Once they’re all connected, put the locking pins back in the centre of the grids. Put your shed floor on top and you’re done! Concrete or paved shed bases For a concrete base or a shed base made from paving slabs, you’ll need to dig a sub-base. For concrete bases, you’ll need to dig down 150mm so you can add 75mm of compact hardcore under 75mm of concrete. For paved shed bases, you’ll want it to be about 120mm deep for 50mm of compact hardcore and the paving slabs. How to build a shed base out of paving slabs Mix sand and cement together to make mortar or use a pre-mixed one Use a trowel to lay mortar for 1 slab at a time on the sub-base and lift a damp-sided slab onto the mortar, using a piece of timber and club hammer to tap the slab into position carefully. Continue to lay the first row of slabs Make equally-sized spacers in all the joints in the slabs to ensure they’re the same size, checking it’s level as you go along Next lay slabs along the two adjacent outer edges, filling in the central area row by row Leave the mortar to set according to the instructions or for at least 48 hours before filling in the joints with mortar or paving grout Building a shed base from concrete Create a wooden frame around your shed base area (also called formwork) to stop the concrete from spreading Mix pre-mixed concrete with water or use 1 part cement to 5 parts ballast Wet the sub-base using a watering can with a rose on the end Pour the concrete onto the framed base starting in one corner Push the blade of a shovel up and down in the edges of the concrete to get rid of air bubbles Use a rake to spread the concrete, leaving it around 18mm higher than the top of the frame. Work in sections of around 1-1.m2 Compact the concrete using a straight piece of timber that’s longer than the width of the base. Move the timber along the site, hitting it along at about half of its thickness at a time until the surface is evenly ridged Remove excess concrete and level the surface by sliding the timber back and forwards from the edge that you started. Fill in any depressions and repeat until even Run an edging trowel along the frame to round off exposed edges of the concrete and prevent chipping Cover the concrete with a plastic sheet raised on wooden supports to allow slow drying. Weigh it down with bricks Once the concrete is set, you can install your shed and remove the wooden frame with a crowbar Don’t fancy having a go at building a shed base yourself?

Question 2

Do I need planning permission for a shed?

Accepted Answer

Generally, you don’t need planning permission for a shed if you live in England or Wales. This applies whether it’s a wooden, metal, plastic or brick shed. However, there are a few conditions your shed will have to meet to not require planning permission: The shed doesn’t cover more than 50% of the garden It’s not in front of your house The shed is single-storey with eaves no higher than 2.5m and the overall height is no taller than 4m for a dual-pitched roof, or 3m for any other type. If it’s located within 2 metres of your property’s boundary, it mustn't be more than 2.5m high There’s no veranda or balcony The floor area is no bigger than 15m2 - up to 30m2 may be covered under Permitted Development if other conditions are met The shed is for domestic use only by those who live in the property and there’s no sleeping accommodation – that means you can’t run a business from the shed unless you apply for planning permission Exceptions Of course, there are always exceptions: If you live in a listed building, you’ll need Listed Building Consent before you can build a shed in your garden If you live in a conservation area or similar, the maximum area of ground covered by outbuildings, pools and enclosures situated more than 20m from any wall of the house mustn’t exceed 10m2 if they’re to be considered as a permitted development If you own a piece of woodland, you must seek planning permission for any permanent structure In Scotland, you’ll need planning permission if any part of the shed comes within 1m of a neighbouring property or is more than 2.5m high In Northern Ireland, there are rules about how close your shed can be from a road that passes by the back of your house. It’s best to check for clarification So if you live in a straightforward house in England or Wales, you shouldn’t need planning permission for your shed. If you’re in any doubt, make sure you check with your local planning office.

Question 3

How to felt a shed roof?

Accepted Answer

Whether you want to felt a new shed roof or you’re re-felting your existing shed roof, it’s simple when you know how. Read our quick guide to see how easy it is. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting. Measure the shed roof Measure the roof, taking into account that you should leave around 50mm for overlaps at the eaves and 75mm at the gable ends. You’ll probably need 3 pieces of felt, but some smaller sheds only need 2. Apply felt to the roof Once you’ve cut the felt to size, apply the each piece to the roof, pulling it tight. Then nail along the length of the roof at 100mm intervals. For nails at the bottom edge, they can be wider – around 300mm. If you’re adding a piece of felt in the middle of the shed along the apex, fix it using adhesive, then nail it at the lower edge at 50mm intervals. Tidy up the overhangs Fold down the felt at each overhang and nail it securely. Cut a slit in the overhang at the apex using a pen knife, then fold that down and nail at 100mm intervals along the gable. If you like, you can add fascia boards to keep the shed looking neat. Use wood nails to secure them and then trim away any excess felt. That’s it. It sounds scary, but it won’t take you long to felt your shed roof as long as you follow instructions carefully.

Question 4

How to make a shed door?

Accepted Answer

There are a few ways to make a shed door and each has their benefits, but we’re going to go through a quick guide on how to make a ledged and braced shed door, which is a good option to stop the door from dropping over time. Tools and equipment required Tongue and groove timber boards Boards for the ledges and braces, at least 20mm thick Nails Hammer Saws, including a circular saw Chisel Mallet How to make your shed door Cut your boards to size If you can’t buy boards at the right height and width for your door, cut the boards to length using a circular saw. Don’t forget to sand and treat any cut ends with timber preservative. Lay out the boards in the best arrangement for your shed door, with the inside of the door facing up. Arrange the ledges and braces On most shed doors, you’ll probably need 3 boards across the back of the door to form the ledges. The ledges keep the door straight and keep the boards of the door together. The braces are the parts of the door that slope down to form a ‘Z’ shape between the ledges. Ensure that the braces are sloped up from the bottom and middle hinge to stop the door from sagging as the timber expands and contracts in the weather. Once you’re happy with the arrangement, mark the spots on the boards where they will meet and cut out of the housings using a chisel and mallet. Put the door together Use clamps to pull the boards together and hold the ledges and braces in place. Nail from the front of the door through the boards and ledges to fix them. Secure the ledges and braces with screws; you may want to pre-drill and countersink holes to prevent the wood from splitting. Remember to treat them with preservative if you do. Fix the shed door hinges Make sure you measure carefully before attaching the hinges, ensuring you know where the pin sits in relation to where the door opens. Treat the door and add locks and handles Apply some wood oil, like linseed or teak oil, to help prevent water damage. Then add locks or handles to your shed to help keep it secure. If you’d rather leave it to the professionals, there are plenty of specialists that will be able to make a shed door for you, or even put up an entire shed.
