Loft conversion - suggestions for a creative architect?

I think you'd need to speak to a specialist to see if that particular spiral could be modified and extended - but I can't see anything stopping it being changed for a similar, but taller one.

Would building regs be an issue for a spiral staircase connecting three floors?

I'm thinking spread of fire/smoke and means of egress, particularly given the ground floor is open-plan - containing an open fire and no doors separating the kitchen.

Even if not prohibited I'm not sure I'd sleep easily in the resulting loft room, or let my kids sleep up there.

If you go on rightmove sold prices, type in the postcode, from there you can view some of your neighbours layout, they may have the same set up as you, so could see if any have extended and how.

Some of the neighbours seem to have done loft room conversions, but still advertised as 2-beds.

Also worth noting that there are two/three styles of house in this terrace - some have a parapet wall between each house, others (like the one of interest to the OP) are a pair with no parapet wall between them.  That would make me curious about what (if any) loft-space division there is between the paired properties - and the cost/feasibility of upgrading it to a living space standard.

Thanks @Section62, that's a good question. There is loft-space division, but not sure what kind. I'll see if it's mentioned in the survey.

Yes, this is a very good point. Building Regs won't let you have three storeys where the stair is open to the room, you would need to put a hall back in - which may not be very possible judging by the stairs location.
