Conservatory roof suggestions Please

[jassdhali]

Hi,
looking to build a conservatory on the side of my house off the kitchen. It will be accessible through exterior bi-fold doors and is exempt from Building regs as it fits within the criteria.
Also the main wall is within 1m off boundary wall so will be completely bricked & exempt from glazing calculations as per Application of Part L to Conservatories.
The issue I have is I would like to use the room through winter period also so obvioulsy with a roof glazed not less than 75% it will get bloody cold or my heating bills will go through the glass roof
Any suggestions on how to achieve a better thermal roof? The only stipulation is that I do not want to get a building notice as the house is built close to a mineshaft and we were recently granted planning permission on a further extension to the living area but not Building regs approval to build it, due to the 'possible' existence of the shaft.
Ideas & thoughts welcomed.

Put a solid roof on it and call it a porch...

jassdhali you can build the roof out of solid insulation if you like. Provided it meets 3.16 or failing that 4.8 you will be exempt from inspections. Just build it as you would an extension.

Can call it a porch, which is cool, BUT council say anything over 3m square requires planning permission, regardless of where the porch is situated, ie/ rear or side of house, as long as its not a habitable room.

Planning and building regulations rules classify porches for specific reasons. But they are not interchangebale - what planning calls a porch is not the same as what building regs call a porch. For your purposes you are building an extension for planning and a porch for building regs.
