I have recently moved into my first new build home which is subject to the NHBC guarantee. I'm hoping you guys can answer my query as am not sure where to turn for the answer!
The patio in the back garden is at the same height as the sill at the bottom of the patio doors which means that it sits above the damp proof course. From my research on the internet, I understand that the ground level should always be at 150mm below the damp proof course.
I have argued this point with the housebuilders, however they tell me that the patio meets the current Part M Building Regulations for disabled access. (I would like to point out that the disabled access at the front of the house is more than adequate)!!
Can anyone with any accurate knowledge of the building regulations inform me who is correct please!! I don't want to suffer with rising damp in the future but haven't got a clue what step to take next!
