GRANNY ANNEXE FOUNDATION

     Using screw piles as a standard foundation for garden buildings is an excellent choice. Screw piles, also known as helical piles, are steel piles that are screwed into the ground using hydraulic machinery. They provide a strong, stable, and durable foundation for garden buildings.

One of the main benefits of using screw piles is that they can be installed quickly and easily, without the need for extensive excavation or concrete pouring. This can help reduce the time and cost of construction.

Screw piles are also very versatile, and can be used in a variety of soil conditions. They work well in both soft and hard soil, and can be used in areas with high water tables or other challenging soil conditions.

Another benefit of screw piles is that they are environmentally friendly. They do not require the use of concrete or other environmentally harmful materials, and they can be easily removed and reused if necessary.

.Each building comes with 1250 mm deep screw piles but depending on soil condition or building control this can go up to 2550 mm deep or different system as is Raft foundation as an extra .

GARDEN BUILDING SIP-FOAM INJECTED PANEL KIT

    SIP panels, or structural insulated panels, are an excellent choice for the base structure of garden buildings. They are made up of a layer of rigid foam insulation sandwiched between two structural boards, usually oriented strand board (OSB).

SIP panels offer several benefits for garden buildings. First and foremost, they are very strong and provide excellent structural support. This is important for garden buildings, which may be subjected to harsh weather conditions, such as wind and snow loads.

SIP panels also provide excellent insulation, which can help keep the garden building warm in winter and cool in summer. This can be especially important if the garden building will be used as a workspace or living space.

GARDEN BUILDING ELECTRICS

    It is important that all garden rooms have a separate consumer unit with RCD (residual current device) protection to ensure electrical safety. This is because garden rooms are typically located outdoors and may be exposed to moisture, which can increase the risk of electrical shock.

An RCD is a safety device that can quickly disconnect the electricity supply if it detects an earth fault, which can occur if electricity leaks from a damaged cable or appliance and flows through a person's body to the ground. By disconnecting the supply, an RCD can help to prevent serious injury or death.
