What we build

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 8

Extensions

Single-storey glazed extensions with lantern roofs, bi-folds and roof lights — groundworks and glazing under one quote.

Why homeowners choose us

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.”

How we work

Four steps, no pressure at any of them

01

A conversation

Call or send an enquiry and Mike will talk through what you are planning, the property and whether we are the right fit.

02

Free home survey

We measure properly, check the base, drainage and access, and discuss what will genuinely work on your elevation.

03

Written quote

A fixed price with the full specification set out — frames, glazing, roof build-up, groundworks and finish. If it is not included, it says so.

04

Install and sign-off

Our own teams fit the project, we register it with FENSA where applicable, and Mike inspects the finished job before we invoice.
