• 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.

Properly installed wooden decking will not need a lot of maintenance. Most manufacturers recommend regularly brushing leaves and dirt off the deck, and a yearly cleaning and staining procedure. This will keep the wood in the best condition. Fluids and treatments are readily available from all DIY shops and stores.

The cost of wood flooring varies by the type of wood and by the finish required. As a guide though oak solid wood flooring cost about £35 - £45 per m2. The average wooden cost by material are approximately £40 per m2 for pine, £45 per m2 for cherry, £60 per m2 for maple and £75 per m2 for walnut. This price does exclude the laying of the flooring and the underlay required.

1. 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
2. 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

1. If you’ve not got an overhang or it’s a fixed deck, fit starter clips along the outside edge of the frame and secure with screws provided with the composite decking. If you are working with an overhang, put the first board into position not exceeding 25mm. If you’re adding a fascia, put an off-cut of board under the overhang so you know it’ll be flush with the fascia.
2. Pre-drill all fixing points, measuring in 30mm from the edge of the board. Secure the board to the joist below with composite decking screws.
3. Slide a hidden fastener clip in so it sits within the groove of the deck board. It needs to be in the centre of the joist to keep the boards secure and ensure an expansion gap of 6mm. Tighten the clips until just tight, and repeat so there’s a clip at every joist.
4. Add the next board, ensuring that the fastener clips sit within the groove – make sure you don’t force it. Repeat step 3.
5. Continue steps 3 and 4 until you’re at the final board, which you should secure in the same way as you did the first.

1. Start in one corner of the sub-frame and position the first board across the inner joists. You want the deck board in the opposite direction to the inner joists, ensuring that it’s flush with the frame. Position any end-to-end joins between the deck boards halfway across an inner joist so you can screw both boards into the joist for stability. Make sure you keep a gap of between 5-8mm to allow for expansion of the wood.
2. Begin to screw your deck boards to the joists. You’ll need to secure the deck board to every joist is covers along your deck frame. Use two screws for every joist. Mark where you’re going to add your screws, ensuring that they are at least 15mm from the end of the board and 20mm from the outside edges. Drill pilot holes for the screws, being careful to only drill through the deck board and not the joist. Then screw the decking screws into the holes.
3. Continue to screw in the deck boards, ensuring you leave the correct expansion gap. You can stagger the deck board joins across the deck for more strength.
4. Sand down any cut ends if you need to before applying decking preserver to protect the timber from rotting.

Most of the people out there do not know the difference between a carpenter and a joiner. This is a very common question that is asked by many as to whether there is an actual difference between the two.

Both joiners and carpenters have many shared traits. The definition seems to change throughout the UK. The southern parts use the term carpenter whereas the north seems to prefer the term joiner. Both of these trades involve working with wood mainly in the construction industry. Both of them are, however, are two very unique and separate trades. Both of them come under the broad term of ‘carpentry’ however their skills and specialisms differ.

A joiner is defined as a trained craftsman who is responsible for making or joining wood in a workshop. On the other hand, a carpenter is a professional that works on site with the timber. In summary, a joined creates the wood back at the workshop while the carpenter fixes them on site. A joiner, therefore, works on things that are done in a workshop using machinery while a carpenter is responsible for its assembly on site.

As both joiners and carpenters had learnt the basics of both trade while they were practising as an apprentice, several similar overlaps are bound to occur.

It is good practice to ask the company or the individual what trade they specialise in. As an example, a joiner may be able to make a particular item whereas a carpenter may be better doing the actual fitting.

It is evident from the above sections that carpentry and joinery are completely different and therefore, should be categorised under two different trades, however, there is indeed a lot in common in their extremely high skilled work.

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.
