Title: Is a protected route required?
Post by: JC100 on February 08, 2012, 08:43:48 AM

Hi all, wonder if you could help.

A 3 storey residential property is split into two blocks, one containing 4 units and the other 9 units. In the larger block, with 3 units per floor, there is a protected staircase. In the smaller block, there are 2 flats on the 1st and 2nd storey only but no staircase protection is provided; the ground floor is purely for access. The property was built in 1995 as far as i can find. Any ideas why this might be, is a protected stair not required if only 2 units per floor and if so, where can i find information on this?

Thanks

See the footnote to paragraph 2.19 on page 26 of ADB B1 2006.

You need to quote the 2001 version, I believe the content is the same but IIR the numbers might be different.

See also pages 88 and 89 of the purpose built flats guide issued last August, it provides the ADB benchmark and relaxations for small single stair blocks.
