Garden Sheds in Knebworth

Garden sheds are an essential aspect of any useful garden space. They provide storage for bulky garden tools, as well as for other tools. A large garden shed could even offer enough room for plant potting or a general workshop. Additionally, a big shed could be used as an indoor sitting area. Garden sheds come in a large array of sizes and can be specified to your particular needs, providing you full control over the amount and position of windows, type, size and location of door, and design of roof. Garden sheds commonly come in one of three materials. Wooden sheds are the typical style and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to adjacent fences. Wooden sheds are still very popular, although they will require maintenance by retreating or staining the wood to maintain the life of the shed. Garden sheds are also manufactured from metal, which is very strong and therefore great for storage of tools and other equipment. Metal sheds also require almost no maintenance. The final material for garden sheds is plastic, which in modern examples is much more resilient than might be expected. When considering a garden shed, it's vital to make sure that you choose one that will fit in your garden space. Garden sheds will need to be sited on a flat area, and will require a base to be built as a foundation. This base could be made from either concrete, paving, gravel or a floating wooden base, but will need to be the right size for your shed and able to support the weight of your shed when loaded.

The civil parish covers a location between the villages of Datchworth, Woolmer Green, Codicote, Kimpton, Whitwell, St Paul's Walden as well as Langley, as well as incorporates the town of Knebworth, the tiny village of Old Knebworth as well as Knebworth House.

FAQs

How to insulate a shed?
If you spend time in your shed, whether you use it as a summer house or an office, you’ll probably want a bit of insulation in there for when it starts to get chilly. There are different ways to insulate a shed, and some aren’t expensive at all. You just need to decide what the best way for you is. Bubble wrap If you don’t spend too much time in your shed, bubble wrap is an easy and cheap way to insulate your shed. Simply attach bubble wrap strips to the framing of the shed to create an air gap, then screw or nail a sheet of MDF over the top. Fibreglass wool Fibreglass wool is a good option if you want to insulate your shed further. Make sure you use safety equipment to protect your eyes, nose, mouth and hands when you’re handling it. Tack a breathable membrane to the inner walls of the shed, then place the fibreglass wool on top. Add a sheet of MDF or wood board, ensuring all the fibreglass is covered. Insulating shed windows and doors You'll often feel draughts through shed windows and doors, and these are easy to block up. You can use foam filler or liquid wool along the edges of the windows and gaps in the door frame. Let it dry out after you’ve applied it then cut off any excess. Insulate the floor If you’re building a new shed, you could fit some underfloor insulation to the grid of the shed base – it could help reduce up to 40% of heat lost through the shed floor. But if your shed’s already built, you can line the floor with a breathable membrane then lay a rug or piece of carpet down. The membrane underneath stops any damp or rot forming, so it’s best not to lay a rug straight down on the shed floor.
How to build a shed?
A garden shed is a great option to add extra storage space in your garden. Lock away your lawnmower, tools, outdoor toys and furniture so it doesn’t get weather damaged or stolen. But how do you build a shed? We’ll go through a brief guide on building a shed using a flat packed one.
  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.
    8. 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.
How to build a shed base?
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.
  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

Where should I put my garden shed?

Try to put your shed in open space, away from trees, bushes and other buildings. This will help to protect it from falling branches and sap. It will also mean that you can access all sides of the shed for repair and maintenance purposes. Make sure you take a look at garden shed planning rules before you pick a final spot for your shed.
