Vijay Posted July 23, 2017 Share Posted July 23, 2017 Is 100mm the norm when it comes to the step down from the house to an attached garage? My AT suggested making it 150mm to replicate 2 brick courses but I just can't see the point??? Link to comment Share on other sites More sharing options...
Ian Posted July 23, 2017 Share Posted July 23, 2017 The regs in Part B call for a minimium of 100mm so 150mm is okay. The alternative to a step is a ramped floor to the garage. Link to comment Share on other sites More sharing options...
Vijay Posted July 23, 2017 Author Share Posted July 23, 2017 Cheers Ian. But is there any advantage with going more than a 100mm step? The only thing I can think of is it would bring it level with the external ground level, but I think it best to have a 100mm step and then a final slope towards the external doors, so they finish level with the external ground (150mm below FFL) Link to comment Share on other sites More sharing options...
PeterW Posted July 23, 2017 Share Posted July 23, 2017 50mm slope is a big slope and you will notice it unless your garage is 10m or more. I would go the 150mm - it's not a difficult step as it's less than an ordinary staircase. Makes it easier if you put a landing on the door side in the garage so you don't jolt down.

Vijay Posted July 23, 2017 Author Share Posted July 23, 2017 Garage is just under 13m externally but I'm having front and rear doors (garage door at front and some sort of french doors at the rear) Link to comment Share on other sites More sharing options...
Temp Posted July 24, 2017 Share Posted July 24, 2017 The rules have changed. There is no need for any step if the floor slopes away from the door to the house. Link to comment Share on other sites More sharing options...
Vijay Posted July 24, 2017 Author Share Posted July 24, 2017 (edited) But there doesn't seem to be any specs for the slope ratio Edited July 24, 2017 by Vijay Link to comment Share on other sites More sharing options...

Personally I wouldn't want a sloping floor to my garage as I have floor mounted racks etc in mine and a flat floor is obviously better if you use your garage for storage.
