How to take down a conservatory

We want to remove our leanto conservatory and replace it with an open outdoor seating area with a low half brick wall. How big a job is demolition? And will we need to get planning permission for this change?

"No you don't need planning because it's a open space area at ground level and taking away the conservatory reduces the built volume it's considered a none complex project"

"Hi there

This isn't a huge project, and can be done within a week or so. You're costs will be waste removal allowances and labour to remove the conservatory itself. You also wouldn't need planning permission!

All the best

"It is unlikely to be subject to planning and shouldn't be a particularly expensive job"

"Hello Joyce,
Presuming the existing conservatory is a plastic or wood construction....the details de-consruction
Of it would be reasonably easy to do. Only to arrange a skip to take it away.
Once it is down a seating design could be made and built....for an all round builder this is very doable."

"Demolishing a lean-to conservatory is usually a straightforward job and can often be completed in 1–2 days, depending on its size and construction. Typical costs, including demolition and waste removal, are around £800–£2,500. Replacing it with a patio or seating area and a low brick wall will add to the overall cost depending on the design and materials. In most cases, planning permission isn’t required to remove a conservatory, but it’s always worth checking with your local council if you’re making additional structural changes. A site visit will allow a contractor to provide an accurate quotation."

"First remove all glass and then dismantle the roof and then the doors and then the supports ."

"How big a job would depend on the size of the conservatory itself but the simple answer is its not difficult if you have some basic knowledge. It will make it an easier job if the conservatory its to go into a skip because you can be a less careful with taking it down without worrying about it breaking. In relation to planning permission unless its part of a grade II listed building you will not require any form of permission."

"No permission required to remove it and most constuction companies can do this scope of works."
