Common questions Stainesai
The price can be affected by the size of the orangery, choice of materials, complexity of design, and location within the UK.
Planning permission may be required for an orangery depending on its size and location. In England, single-storey rear extensions are typically permitted development up to 4 metres for a detached house and 3 metres for a semi-detached or terraced house. Larger extensions may be possible under prior approval. Building Regulations approval is always required. Always confirm with your local authority before work begins.
Yes, Building Regulations apply to structural aspects and energy efficiency of the orangery. Compliance is mandatory.
The process includes excavation, foundation laying, building walls, installing glazing and roofing, and connecting utilities. Building Regulations approval is required if the orangery is over 30m² or involves structural changes. Always confirm with your general_build before work begins.
Ensure your builder is aware that all extensions, including orangeries, require Building Regulations approval, regardless of planning permission. Structural work, such as installing RSJs or underpinning, also requires Building Regulations approval. Always confirm with your general builder before work begins.
