• 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

1. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
2. 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.
3. 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.
4. 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.

• Decking joists
• Coach screws
• Coach bolts
• Combi drill
• Socket set
• A saw suitable for your project and the thickness of the timber
• Pencil
• Decking preservative
• Sandpaper or sander

1. Measure your deck frame and cut to size if necessary.
2. Make 2 pencil marks on each end of the frame’s 2 outer joists to mark where the coach screws will go. They need to align with the centre of the adjoining outer joist. Then, use a flat wood drill bit to drill recesses into each mark. Make them the same depth of the screws that your using’s head and wide enough for a ratchet or socket to tighten them.
3. Using a thinner drill bit, line up the outer joists and drill a pilot hole through the middle of the recess. These pilot holes act as a guide for the screws and stops them from splitting the wood.
4. Fit the coach screws with either a drill driver or socket and ratchet.
5. Repeat the process for the inner joists once you’ve assembled the outer frame.

• Paving slabs – old or cheap ones are fine
• Timber for the frame and legs
• Type 1 MOT hardcore

1. Mark out the area as we explain in ‘How to lay decking’. Then, dig to 200mm below where you want to surface of the decking to be.
2. Add a 50mm layer of hardcore and make sure it’s compact.
3. Build the decking sub-frame as we describe in ‘How to build a deck frame’.
4. Lay out paving slabs along the edges and in the centre of the area. This will help to spread the weight of the decking.
5. Set the decking frame on the slabs, checking for high or low points and adding off-cuts of timber where needed. Don’t forget to sand and seal these off-cuts with decking preservative.
6. Add your joists and then the deck boards, leaving the recommended gaps of expansion of between 5-8mm.

If you’re thinking about making improvements to your home, it’s only reasonable to become familiar with the ins and outs of the requirements to make the project a success. Not just the cost involved to complete the project, but also the duration it’ll take to complete the job and lots more. When it comes to the installation of wooden flooring, there’s a need to find out whether or not an underlay is required for the task. In this article, we’re going to consider this in order to ensure that you’re on the right track. Let’s take a look!

First and foremost, underlays are common with carpets as they allow for an even surface with no lumps and bumps. It also provides a deeper barrier between the carpet and the floor as carpets, themselves, aren’t particularly thick enough to provide adequate comfort when walking on them. Underlay also helps improve insulation which in turn, helps cut down your energy bill. So, are underlays also needed with wooden flooring?

In general, wooden flooring does not really need an underlay. This is due to the fact that they’re perfectly comfortable to walk on without the need to add an extra padding underneath. However, the subfloor will have to be made prior to the installation, as a result, an underlay is needed at all there. With that in mind, it’s highly recommended to make use of an underlay when installing a boarded floor to a wooden subfloor mainly due to the fact that it’s able to provide a much-improved insulation. When it comes to wooden flooring, it’s always best to go for quality rather than looking for ways to cut corners. If you’re able to go for the best project with professional installation and little extras like undelay, you’d notice and enjoy the long lasting nature of your wooden flooring immediately after installation.

1. Place a post in the corner of the frame you created with the pegs and string. Measure and mark out 100mm from each side.
2. Dig out this soil to a depth of 700mm (watch out for cables or pipes). You should have a 300 x 300mm hole. Repeat for the other 3 corners.
3. Using a brick bolster, split a concrete block in two. Put a section of the block in each hole.
4. Get a length of post longer than you need and place one in each hole. You can cut it down later.
5. Create props on each post to hold them in place until you’re ready to add a cement mix. Check that they’re level. When you’re happy that they are, secure them in place with a concrete mix, making sure you create a slope in the concrete so that rainwater runs away from each post. When the concrete is set, remove the props.
6. Create a string line around each corner post and find the centre point between each. Place a timber batten at each point, ensuring that they’re not spaced any more than 1500mm apart.

1. Working from the corner where the deck will be at its highest above ground level, measure and mark on the post where the highest part of the frame will be.
2. Measure from the far side of one post to the opposite and cut sections of joist to size. Line up a piece of joist with the mark you made and temporarily secure it. Factor in a 2mm fall for every metre of decking so rainwater can run off.
3. Secure the frame to the other corner post, ensuring it’s at the right level. Do this for every side of the outer frame.
4. Using 100mm coach screws with washers hanging on the end, secure each end of the four sections of frame.
5. Mark out where the centre of the support posts will be and secure all of these posts to the frame, except the centre post.
6. Add your central support joists. These should run in the same direction as the deck boards will run. You’ll need to measure from the inside of the frame on one side to the inside of the frame on the opposite side. Attach the joist in the same way as you did for the other posts. Repeat so the centre post is in between two sections of frame and secure the posts with concrete.
7. Trim down all the posts to the correct height using a saw.
8. Add your weed-control fabric and weigh down with gravel across the entire area.

1. Measure 400mm from the centre of the outer frame and mark a line. This will be where the first joist is positioned. Repeat at 400mm intervals down the length of the frame – if the last one will be more than 400mm, add another joist to create enough support.
2. Attach a joist hanger to each end of the joist.
3. Place the joist in position so the centre lines up with the 400mm spacer mark.
4. Secure using external grade screws once you’re happy that the joist is flush with the frame.

1. Remove fascias and trims Unscrew or prise off the screws and nails fixing the trims and fascias to your shed.
2. Take off doors and remove windows Unscrew hinges from doors and take them off. Remove all metalwork once the door is off. If you’ve got frames on your windows, unscrew these, and remove the panes. Be extra careful if your windows are made of glass.
3. Take off the roof Prise off the tacks from the roofing felt and take the felt off – you can’t reuse it, so you’ll need to throw it away. Unscrew the screws on the roof boards and slide them off the shed’s frame – you might need a friend to help you do this.
4. Take out the roof brace (optional) If your roof has a brace, unscrew the brackets that hold it to the side of the shed. Remember not to lean on anything once you’ve taken the brace off as the walls might be wobbly.
5. Unscrew the frame from the floor Remove all the screws that are holding the shed to the base, remembering not to lean on the walls.
6. Unscrew the frame corners Starting at the corner of the front gable, remove the screws where the panels meet. Once a panel is free, lift it carefully out of the way so you can carry on with the others.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
