Garden Sheds in Balham

Garden sheds are a significant element of any useful garden space. They can offer storage for cumbersome garden tools, as well as for other equipment. A sizeable shed could even offer enough space for plant potting or a general workshop. Additionally, a substantial shed could be used as an inside seating area. Garden sheds come in a huge range of sizes and can be specified to your particular needs, providing you with complete control over the number and position of windows, type, size and location of door, and style of roof. Garden sheds typically come in one of three materials. Wooden sheds are the traditional design and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to neighbouring fences. Wooden sheds are still extremely popular, although they will need maintenance by retreating or staining the wood to preserve the lifespan of the shed. Garden sheds are also manufactured from metal, which is very tough and therefore great for storage of tools and other equipment. Metal sheds additionally require almost no maintenance. The final material for garden sheds is plastic, which in modern examples is a lot more durable than might be expected. When contemplating a garden shed, it's essential to make certain you choose one that will fit in your garden space. Garden sheds should be sited on a level 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 timber base, but will need to be the right size for your shed and capable of supporting the weight of your shed when loaded.

Balham

Balham is a district in south London within the London Borough of Wandsworth. The settlement features in the Domesday Book as Belgeham. Bal signifies ‘rounded enclosure’ and ham a homestead, village or river enclosure. The region has been settled since Saxon times, and Balham Hill and Balham High Road follow the line of the Roman road Stane Street to Chichester.

Balham encompasses the A24 north of Tooting Bec along with the roads coming off it. The southern area of Balham which is close to Tooting Bec features a block of 1930s Art Deco flats known as Du Cane Court. There's also the Heaver Estate which can be found in Tooting, which comprises substantial homes. It was built inside the grounds of the old Bedford Hill House by local Victorian builder Alfred Heaver.

Balham is located between 4 south London commons, namely Clapham Common to the north, Wandsworth Common towards the west, Tooting Graveney Common to the south plus the connecting Tooting Bec to the east.

In the Second World War, on 14th October 1940, Balham tube station was badly affected by air raids on London. Individuals sheltered inside the tube station during the raids, but a bomb fell in the High Road and through the top of the Underground station, bursting a water and gas mains and killing around 64 individuals. Ian McEwan describes the event in the novel ‘Atonement’, published in 2001.

FAQs

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.

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.

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.
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.
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.
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.
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.
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.
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.

Yes, it is possible to insulate a shed. You might want to do this if you’re planning on working in it during the winter. A professional will be able to help you find an insulated shed or advise you on how to insulate a shed that you already have. Always seek professional advise first before attempting to do this yourself!

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.
