Garden Sheds in Carshalton

1. Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible.
2. Build a timber frame to size.
3. Measure out 4 rows of 3 blocks to create good weight distribution and lay in place.
4. Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat.
5. Place timber planks along the rows of blocks and see how level it is. Add or remove blocks where necessary. If it’s only a small difference, use shingle underneath the timber until it’s level.
6. Nail your timber shed base to the timber planks to create a sturdy base for your shed.

• 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

• 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

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.

• Tongue and groove timber boards
• Boards for the ledges and braces, at least 20mm thick
• Nails
• Hammer
• Saws, including a circular saw
• Chisel
• Mallet

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
