Conservatories in Knowle

Planning your conservatory in Knowle

Many porches and conservatories don't need planning permission, but size, height and closeness to a road or boundary all matter. If yours does, the application goes to Solihull Council. We check the limits against your house at the survey.

Taking out the doors between the house and conservatory removes its building regulations exemption.
On a semi or terrace, a rear conservatory can usually project 3 m under permitted development, or 4 m on a detached house.
The house heating shouldn't simply be extended into an exempt conservatory; it needs its own controls.

Which options suit homes in Knowle?

Lean-to conservatory

A simple rectangle with a single sloping roof running down from the house wall. Lean-tos are the most affordable style, work under low eaves and on bungalows, and make good use of a narrow garden. The plain shape is also the easiest to furnish, and it's often the right choice for a dining or sitting space.

Victorian or Edwardian conservatory

A Victorian conservatory has a faceted, rounded end and a steeper ridged roof; an Edwardian one is square or rectangular with a ridged roof. Both give more height and floor space than a lean-to. They suit semis and detached houses, and a dwarf brick wall can be matched to your existing brickwork.

How much should you budget in Knowle?

Expect to budget between £3,500 and £22,000 depending on size and specification in Knowle. Insulated tiled roof replacing polycarbonate on a 3.5 × 3 m conservatory: typically £7,000–£10,500.

What guarantee do I get on a new roof or conservatory?

Building control issues a completion certificate for notified work, which you should keep with your house documents. Ask us about anything you'd like clarified before you sign.

How much does it cost to replace a conservatory roof with a tiled roof?
