Four ways to add a room
The difference between a conservatory, an orangery and an extension is mostly about how much solid wall you want and how the room needs to perform in winter. We will talk you through which one actually suits your property before anyone talks about price.
Conservatories
Glazed, tiled and hybrid roof conservatories designed around how you actually want to use the room.
Orangeries
Brick or stone piers, an insulated perimeter roof and a glazed lantern — a room that reads as part of the house.
Extensions
Single-storey glazed extensions with lantern roofs, bi-folds and roof lights — groundworks and glazing under one quote.
Replacement conservatory roofs
Turn an unusable polycarbonate conservatory into a room you use all year — usually in under a week.
Three decades of experience
Cotswold Conservatories is run by Mike, who surveys the jobs and inspects them when they are finished. There is no call centre, no pushy salesperson and no chain of subcontractors between you and the people doing the work.
Glazing is our own trade, which matters more than it sounds. On a conservatory, an orangery or an extension, the glass and the roof are what determine whether you actually use the room in February — and that part is never something we buy in.

“Having had an appalling experience with another company before, I decided not to make the same mistake twice and went with the quality supplier. The estimation process was quick and simple and the sales guidance was excellent. The fitters were as good as you can get.”
