Help - advice needed for solid conservatory roof and side windows

Ro

Hi 

I hope someone can help. I have a massive 6m by 6m lean to polycarbonate roof conservatory and want to replace with a solid roof. Question 1 is do I need planning permission?

Second I have had a quote from a supalite roof provider for the roof £19800 only (Edwardian style). The quote for the roof and the windows (these are 6m by 6m of windows about 2 10 high and resting on dwarf walls and to include double doors is 29k.

Has anyone got experience of Supalite roofs and are these quotes about right?

Finally (sorry!) how do I know the base can support the weight? The installer says the new frames (70mm) can take the weight of the roof, but the weight is quite a lot - about 46kg per sq metre.

Ask your provider about building control. If he says not needed, get another provider. Also ask your local building control office. Similarly planning department.

6m x 6m is not within permitted development and building control will also need to be involved as you will need decent foundations. 

£20k for a roof only is a joke, and not a funny one. Get a proper solid roof with a big lantern(s) and flitch beams if you must.

Thanks for the comments - the company offers JHAI building regs sign off for £420 so I am assuming at this stage that the work will meet building regs standard. The conservatory has been there 35 yrs so may not now need permitted development?
If redoing with fitch beams and new foundations would the costs be a lot less - any idea of costs for 36 metres of new foundations and removal of existing fairly shallow base. Thank-you very much for your comments - apologies for my lack of knowledge

Doozer will be along to help you out here. Foundations are expensive but at least you know what you are getting. £20k for a high-tech roof is just too much.

@Doozergirl?

Ripping up and starting again isn't
going to be cheap, but £20k for a roof that isn't a proper roof - not a chance would I pay that.  It's daylight robbery.  

The proper roof on my entire house didn't cost that much, and it's got a 120 square metre footprint!

Thanks Doozergirl, I agree.

Did you see what 'supalite roof' is? Looks like something very sophisticated. If it can be built on the existing foundations and walls, then possibly the cost isn't that hight for 6m*6m roof?

£555 a square metre for some aluminium, insulated plasterboard roof and way too many screws?  

 

The problem isn't just £20k on a roof, it's spending £20k on something that *doesn't have proper foundations*, where the existing structure is uPVC of unknown age with a finite lifespan itself, and the upgrade still doesn't meet building control as an extension.  

It's utterly obscene.   I'd be embarassed to sell it.

It's 35 y.o. and, I think, with brick walls. 

I agree, that a proper extension is much better, but the OP didn't say that they wanted to convert the conservatory to an extension.

They want a warm roof.  If they're spending £20k on it, they should be expecting something pretty special from it - I would!     I'm just pointing out that it isn't special.
