I am planning a loft conversion in the next year or two and will get plans
drawn up nearer the date but I am doing some homework of my own to check
if
the idea if feasible/ affordable.
I have looked at the building regulations and have a couple of questions

1. in the old regs there was a table of joist sizes for various spans, in
the new regs this is now a trada publication (you have to buy separately)
does any one know the figures have changed or would I just be paying 17-50
for tables I already have.

2. Smoke alarms have to be mains powered and linked, my house will end up
3
storeys high so can I use t&e or have to use pyro.

Thanks

Andy

Smoke alarms are wired in 3 core and earth 1.00mm T and earth cable. each
alarm has it's own standby battery.By the time the alarms melt and stop
working with the 'heat' you will no longer be alive !
