I am applying for Listed Building Consent to remove partitions in the basement to make an open-plan kitchen dining room.
Could anyone suggest a suitable specification for a subfloor buildup for installing underfloor heating in a Georgian brick house?
I asked th CO's opinion, but he didn't seem too interested in what I did with the basement.
At the moment, the floor is a combination of brick laid on sand and parts replaced with a thin layer of cement (around 4 cm thick). The brick part looks really nice, very bumpy - like waves - in parts, there is a 4 cm difference in hight over 40 cm.
Once I removed various coverings to expose the floor, the trapped damp evaporated, so damp isn't a big issue. The walls aren't damp either. There is humidity, but only what you'd expect in an old basement. I'd imagine if the floor was heated and there was decent ventilation, any damp would disappear.
Builder wants to put a damp proof layer under insulation and screed, but I'm afraid this may then cause damp in the walls.
Plumber says can't do underfloor heating without insulation below or I'll be heating the earth below.
The floor finish would be the original bricks + reclaimed to match, or flagstones.
