greenhouse to utility room?

A lot of people do heat their conservatories from the main system, although technically it does alter the status of it. It's why some go for electric underfloor heating.

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.

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.

Absolutely no idea on cost. But I'd be looking for a handyperson and not a builder. It would have to be a competent hp, but it shouldn't be complex.

You may even wish to consider using an off-the-shelf shed? 

Some points: you'll want to keep all timber off the ground, so something should be used between the patio slabs and the main wall construction. Perhaps just a row of bricks, with the added benefit that it can be used to get it all level. And a DPM between this and the timber baseplate. And, you'll really want a floor of some sort, surely, even if only timber decking tiles, which can be easily lifted to access the mh cover.
