"Insulated garden studio, fully wired, plastered and finished — six weeks from survey to keys. It reads as an extension of the house, not a shed."
"A 7m bifold set across the back of our Chiltern barn conversion. Faultless install, faultless finish. The traffic door is a small detail that we now use every day."

- Most conservatories fall under permitted development — a rear single-storey addition up to 3m (semi/terraced) or 4m (detached), under 4m tall, and not covering more than 50% of the original garden. We assess this at survey and handle any lawful development or full planning application on your behalf.

- Do conservatories need Building Regulations approval?
- Not usually — a conservatory separated from the house by external-quality doors (i.e. French, patio or bifold), with independent heating controls, is normally exempt. An orangery with an open connection to the house does require Building Regs and we handle the submission.
