How to build a shed base on uneven ground?

Building a shed base on uneven ground can be as easy as digging out a sub-base and checking that it’s level. You can dig down until the soil is light brown and rather compact, then work out where the ground is uneven and move soil around to compensate. Add a weed-blocking membrane down then put plastic grids in to act as your shed base or continue to make a sub-base for paving slabs or concrete. However, you could also build a timber shed base on uneven ground using concrete blocks to level it out. Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible. Build a timber frame to size. Measure out 4 rows of 3 blocks to create good weight distribution and lay in place. Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat. Place timber planks along the rows of blocks and see how level it is. Add or remove blocks where necessary. If it’s only a small difference, use shingle underneath the timber until it’s level. Nail your timber shed base to the timber planks to create a sturdy base for your shed. If you’ve got any questions about building a shed base on uneven ground, it’s best leaving it to the pros. Get in touch with a range of builders who will be able to offer you a quote.

How to felt a shed roof?

Whether you want to felt a new shed roof or you’re re-felting your existing shed roof, it’s simple when you know how. Read our quick guide to see how easy it is. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting. 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. 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. 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. That’s it. It sounds scary, but it won’t take you long to felt your shed roof as long as you follow instructions carefully.

Garden Sheds in Caernarfon

Garden sheds are a vital component of any practical garden space. They provide storage for large garden tools, as well as for other equipment. A generous garden shed may offer enough room for plant potting or a general workshop. Additionally, a sizeable shed could be used as an indoor sitting area. Garden sheds are available in an enormous choice of sizes and can be specified to your particular needs, providing you with 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 classic style and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to adjoining fences. Wooden sheds remain extremely popular, although they will need maintenance by retreating or staining the wood to preserve the lifespan of the shed. Garden sheds are also constructed from metal, which is very strong and therefore ideal for storage of tools and other equipment. Metal sheds also require hardly any maintenance. The final material for garden sheds is plastic, which in modern examples is far more durable than might be expected. When considering a garden shed, it's vital to make sure that you select one which will fit in your garden space. Garden sheds should be located on a level area, and will require a base to be built as a foundation. This base could be produced from either concrete, paving, gravel or a floating wooden base, but will need to be the right size for your shed and capable of supporting the weight of your shed when loaded.

Caernarfon

Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of 10,000. It lies along the A487 road, around the eastern shore of the Menai Strait, opposite the Isle of Anglesey. Bangor is 8.6 miles (13.8 kilometres) to the north east, whilst Snowdonia borders Caernarfon towards the east and south-east. Carnarvon and Caernarvon are Anglicised versions of the name which became old fashioned in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are close by. Rich natural resources around the Menai Straits enabled humans to live in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the location through the period known as Roman Britain. The Roman fort Segontium was created around AD 80 to control the Ordovices throughout the Roman conquest of Britain. The Romans controlled the region until the end of Roman rule in Britain in 382, then Caernarfon became a part of the Kingdom of Gwynedd. In the late eleventh century, William the Conqueror ordered the building of a motte-and-bailey castle at Caernarfon as a part of the Norman invasion of Wales. He was unsuccessful, and Wales remained independent until about 1283. During the 13th century, Llywelyn ap Gruffudd, ruler of Gwynedd, refused to pay homage to Edward I of England, which led to the English conquest of Gwynedd. This was followed by the construction of Caernarfon Castle, among the largest and most imposing fortifications constructed by the English in Wales. The city has come to be an important tourist centre and seat of Gwynedd Council, with a thriving harbour and marina. Caernarfon has grown beyond its medieval walls and experienced heavy suburbanisation. Its population consists of the biggest percentage of Welsh-speaking citizens anywhere in Wales. The castle and town walls are a part of a World Heritage Site described as the Castles and Town Walls of King Edward in Gwynedd. For all your house improvements, make certain that you work with reliable specialists in Caernarfon to make sure that you get the best quality service .

FAQs

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.

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.

Building a shed base on uneven ground can be as easy as digging out a sub-base and checking that it’s level. You can dig down until the soil is light brown and rather compact, then work out where the ground is uneven and move soil around to compensate. Add a weed-blocking membrane down then put plastic grids in to act as your shed base or continue to make a sub-base for paving slabs or concrete. However, you could also build a timber shed base on uneven ground using concrete blocks to level it out.
