greenhouse to utility room?

An electric one would be expensive to run with the current price of electricity. A gas or paraffin powered one could produce dangerous levels of carbon monoxide (CO, not CO2). So a CO alarm in there would be prudent if you do use one.

Rather than an old greenhouse or conservatory which would probably look pretty manky, what about using SIPS to make a structure linking the back wall of the kitchen to the garage wall?

thanks for this suggestion - the maximum width though is 1.2m and it would need to be at least 1.8m wide.

We can cut our panels to bespoke sizes, please see the Cut Panel product under the Extras section.

thanks for this but is it suitable as a roof?  is it waterproof?

Bozzy, who is going to build this? 

For your intended purpose, I would still look to insulate it to a reasonable standard, but not to 'habitable' room regs. And if you fit a glass panel in the roof - or a southish-facing window - then good chance it'll be mild enough in there for its intended use for most of the time. You could always sit an oil-filled rad in there to take the chill off, if needed.

So, timber stud construction, sheathed in 9mm OSB, either both sides to make a sandwich, or just on the inside, fully - tightly - filled with expanded polystyrene insulation sheet like Jablite? Ditto for floor and ceiling. It will need ventilation, at a trickling level. Box-section sheet for the outside walls, or similar - depends on how nice you want it to look.

Roof construction? Your choice - EPDM, felt, cladding. A roof light will make this more awkward, but perfectly doable.

How are you intending to maintain access to the manhole and the drain that runs under it? This serves your own property and possibly that of your neighbours.

Good point. You'll need a hatch in the floor!

Thanks so much for this.  We were hoping to have glass roof to allow plenty of light in and sunlight.  We will only use this room primarily to house our washing machine and tumble dryer. will have a sink in there too.  the patio floor will remain as it is so no plans to change flooring.  Based on what you said above - what sort of prices are we looking at so I know a ball park figure before getting the builders in for quoting.

Thanks Macman - we are at the end of cul se dac and we have no intention of covering the manhole.  it will remain as it is and easily accessible.

there is a manhole in the patio which will remain as it is.

Just a comment on the question of having a radiator in this new room.  I don't doubt that it theoretically changes the room into a habitable space and needs building regs - BUT - when my neighbour had their conservatory built their central heating was extended into the conservatory and they didn't have building regs approval.  When we had our conservatory built we were asked the same question but went for underfloor heating instead.
