FAQs
Do I need planning permission for a conservatory?
Most conservatories are covered by permitted development rights. However, you'll need planning permission if the conservatory would exceed 50% of the total area around the original house, or be taller than 4m.
What is an orangery?
An orangery is a higher-spec extension with a flat or lantern roof rather than a fully glazed conservatory roof. They look more like a full extension and offer better insulation.
How long does a conservatory take to build?
A standard uPVC conservatory takes 1–2 weeks to install. Larger timber or aluminium projects, including foundations, can take 3–6 weeks.
Can a conservatory add value to my home?
Yes — a well-built conservatory can add 5–7% to your property value and significantly increase usable living space.
