1. Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m² 10 x 6 = 60m²
2. Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m²
3. Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m² / 0.358m² x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.

• What you need the shed for
• How much space you have
• How big you need the shed to be
• Which style of roof you want
• What material you would like
• How big your budget is

• Hand-crafted from Nordic White Spruce
• Felt roof reinforced with high-grade polyester
• Tongue and groove cladding makes it more weatherproof so ideal for items that must be kept dry

• High eaves for more head height and to store taller items
• Pent roof and fixed windows allow lots of light
• Ideal for putting up against a wall or fence
• Door can be hinged either side

• Ideal for small gardens or those with fewer tools to store
• Apex roof for water runoff
• Tongue and groove walls
• Tall floor-to-gable door

Yes, although you should make sure that the terrace or decking is able to support the weight of a hot tub. Usually, you will need to have a structural survey carried out on the area. Seek the advise of a hot tub retailer or installer about the logistics of installing one at your property.

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.

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. 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

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.
