From the SCOTTISH building regulations (where Peediedj lives). http://www.sbsa.gov.uk/pdfs/FAQ07.pdf

20. Is there any building work that is exempted from the requirements of the Building (Scotland)Regulations 2004?
[FONT=Arial,Arial][FONT=Arial,Arial]Yes. Certain broad categories of buildings are exempt, and the full list is included in schedule 1 in section 0 of the Technical Handbooks. Some examples covering the small buildings associated with houses, flats or maisonettes that are exempt from the building regulations are given below. If you are not sure, you should seek advice from a professional or the verifier.[/FONT]

[/FONT]c) A single-storey conservatory or porch with a floor area of not more than 8 square metres that is attached to an existing [FONT=Arial,Arial][FONT=Arial,Arial]house[/FONT][/FONT], and:

• is at least 1 metre from a boundary,

• does not contain a fixed solid fuel, oil or gas appliance,

• does not contain a sanitary fitting,

• meets the regulations on safety glazing;

Fine if you live in Scotland. In England the regs are move relaxed and you will not need building regs unless the room will be heated or there is no door between the house and new conservatory.

Like said previously, putting insulation in the walls will make little difference, in the floor would make the floor warmer to bare foot though. To meet building regs you would need....

o- proper foundations, most companies just use 200-400mm. Building regs normally require 600mm+ but this depends on the ground.
o- insulation. 70mm cavity with fiber insulation. 100m->200mm insulation in the floor.. its extremely unlikely you would ever get the heat less of the conservator down to building regs levels. Normally you need to offset it against the rest of the house which is done by adding lots and lots of insulation to the existing house well above building regs requirements, eg 350mm fiber in the loft.

10k may not be over the top for a conservatory of that size but it all depends where you live and final specification. Sounds like you getting sockets added, 35mm room which are 'upgrades' and will add to the cost.

About planning permission......

I live in the Midlands and I need planning permission for my conservatory!

You have an allowance of 70 cubic metres that you can use without planning permission, HOWEVER, if the extension is within 5 metres of an existing structure (a garage in our case) the garage volume is counted as part of the 70 cubic metres!!! As our garage is over 70 cubic metres on it's own we need planning permission to put a conservatoryon the back of our house.

Oh and our conservatory quotes are around £15k, but that is for a 5.1m X 3.5m p-shaped conservatory with a Pilkington Activ Blue glass roof.

A conservatory will require planning permission if you have already used up your pd (permitted development).. Which is a completely different thing to Building Regulation Approval which is what we were talking about....

Hi there

I currently have a double glazed conservatory with a polycarb roof.

The room is pretty much unusable in winter due to the cold.

Trying to work out whether using a product such as Polycool polycool.co.uk would be better (this looks like it fills in the cavity with an insert to insulate) or go the insulated glass method conservatoryland.com/page.asp?page_id=85

Any ideas/recommendations?

thanks

Sat in our conservatory with the poly roof right now. Got a little heater going and it's toasty :-)

yup mines the same easily heated up,so far from unuseable

I live in the midlands and have a 23x13ft conservator, admittedly it is probably 10-15 years old but it is freezing in the winter, usually a couple of degrees above the outisde temperature without heating. It is unusable after October until May unless you can stand the cold better than I!

We are looking at options to try and improve it's usability (which is how i found this link) otherwise it's getting demolished and rebuilt as a proper extension.

sorry - to re-explain. I understand using a heater it will be more usable in the winter months - but what in your opinion would be the better insulator, to ensure all the heat generated just doesn't go straight out via the roof?

a) A product such as Polycool - polycool.co.uk (this looks like it fills in the cavity in a polycarb. roof with an insert to insulate)
or
b) The insulated glass method - conservatoryland.com/page.asp?page_id=85
