1. Base Types

a. Concrete Slab Base

• Pros: Durable, long-lasting, stable surface, suitable for heavy loads.
• Cons: Requires professional installation, can be costly.

b. Paving Slabs Base

• Pros: Easy to install, provides a level surface, cost-effective.
• Cons: May require regular re-leveling, may not be suitable for heavy loads.

c. Timber Bearers Base

• Pros: Simple to install, cost-effective, suitable for uneven ground.
• Cons: Less durable than concrete, may require more maintenance.

d. Gravel Base

• Pros: Allows for good drainage, easy to install, cost-effective.
• Cons: May not provide as stable a surface as concrete or paving slabs.

2. Size and Layout

Consider the size of your shed and the layout of your garden. Ensure the base dimensions align with the shed's footprint, leaving a little extra space around the edges for maintenance.

3. Ground Preparation

Choose a flat, well-drained area for your shed base. Remove any plants, debris, or rocks that may interfere with the base.

1. Planning Permission

In the UK, garden sheds typically do not require planning permission if they meet certain criteria:

• The shed is single-storey and less than 2.5 meters high (or 4 meters with a dual-pitched roof).
• The shed is located at least 2 meters from any boundary.
• The shed does not take up more than half of the garden area.

However, it's advisable to check with your local council, as rules may vary depending on your location.

2. Building Regulations

If the shed will be used for sleeping accommodation or exceeds certain size limits, it may require building regulations approval. Consulting your local authority or a professional is crucial in such cases.

1. Site Selection

Choose a flat area that's slightly larger than the shed's dimensions. Ensure there's good drainage to prevent water accumulation.

2. Base Preparation Steps

a. Concrete Slab Base

• Dig a hole to a depth of around 7.5 cm.
• Lay a framework of wooden planks to contain the concrete.
• Pour and level the concrete mixture.

b. Paving Slabs Base

• Dig out the area to a depth of about 10 cm.
• Lay a bed of sharp sand and compact it down.
• Position the slabs, ensuring they're level and evenly spaced.

c. Timber Bearers Base

• Position and level the bearers on a bed of gravel or compacted sand.
• Use a spirit level to ensure they're even.
• Secure them in place with screws.

d. Gravel Base

• Dig out the area to about 10 cm deep.
• Fill with a layer of hardcore, compacting it down.
• Add a layer of gravel and level it.

Tools:

• Spade and shovel
• Spirit level
• Tape measure
• Hammer
• Saw
• Power drill
• Screwdrivers
• Nails and screws
• Safety gear (gloves, goggles)

Materials:

• Concrete mix (if using a concrete base)
• Paving slabs, timber bearers, or gravel, as per chosen base type
• Gravel or sand (for leveling)
• Damp-proof membrane (for timber bearers)

1. Follow Manufacturer's Instructions

Carefully read and understand the assembly instructions provided by the manufacturer. Pay close attention to any specific requirements or recommendations.

2. Teamwork and Safety

Enlist the help of a friend or family member, as assembling a shed can be a sizeable task. Ensure you follow safety guidelines, especially when working at height.

3. Take Your Time

Rushing the assembly process can lead to mistakes. Take your time, double-check measurements, and ensure each step is completed accurately.
