Updating my conservatory

Hi,

we’ve a conservatory on the rear of our house (around3.5 x3m) which is a good amount of space but it’s boiling in summer and freezing in the winter so we’re wondering how to beat convert it so it’s a more usable space all year around. It’s got a brick wall to around 1m high, then it’s all UPV construction and roof.

My first thought is that the roof could be replaced for an insulated and tiled roof with a window light, but I’m not sure if we would need to have the PVC uprights replaced with a different construction?

Would anyone be able to hazard a guess as to what kind of cost I might be looking at?

Also does anyone know if regs would allow for us to remove the current door between the kitchen and conservatory or does there need to be a physical door between?

many thanks,

john

Replace the roof with a new lightweight tiled one without any changes to supporting structures. Plenty of firms around offering this now.

No idea on costs for your scheme but plenty of companies are advertising such conversions- get them in to quote.

The main thermal gain will come from insulation- if you had the headroom you could underdraw with 150mm PIR and plastic ceiling slats for not a lot of money (£500 materials), if you already have an opening rooflight then make a well for it.
Tiled roof might be too much for the (probably non-existent) foundations as well as for the window bars
To comply with building regs you must have a fixed door between conservatory and house and the conservatory must not be connected to the main house heating system. Even if you reroofed etc. it would still be a conservatory.
The door requirement can be ignored until you come to sell the place- or you can just wedge it open. The heating one is more difficult to ignore (but could be done)- again would have to be removed if you come to sell the place.
If you have the cash, why not consider scrapping the thing and building a real extension?
