The government has unveiled plans to force developers to put second staircases in all new housing blocks above 30m, marking a significant victory by fire safety campaigners in the wake of the Grenfell Tower fire.

In a issued in the dying hours before the Christmas break, the Department for Levelling Up, Housing and Communities proposed introducing a mandate for a second staircase on new blocks above 30m 鈥� around 10 storeys 鈥� in order to 鈥渕ake buildings safer鈥�.

This is despite the fact the measure, which has long been called for by the RIBA and which will cost the industry 拢1.6bn over a decade, was not recommended in the review of building safety regulations by Dame Judith Hackitt conducted in the immediate aftermath of the 2017 blaze.

While it is currently only being consulted upon, the consultation document said the government was considering bringing in the measure with only a 鈥渧ery short鈥� transition period that would allow existing permitted schemes to be completed, but 鈥渟hould not allow the opportunity for developments to get off the ground ahead of the new requirements coming into effect鈥�.

The consultation added that it was encouraging 鈥渁ll developments to prepare for this change now鈥�.

好色先生TV safety minister Lee Rowley said: 鈥淭here are undoubtedly lessons still to be learnt from the Grenfell Tower tragedy and the Department for Housing is committed to working with the sector and residents to explore what more needs to be done to make new homes across the country safe.

鈥淭his consultation is the next step in the department鈥檚 work to improve building regulations and make sure they are as clear and effective as possible.鈥�

The consultation said that the requirement for a second staircase would not permit 鈥渟cissor鈥� or interlocking stairwells that would not protect against the spread of smoke from one stairwell to another, with the provision of an alternative stairwell in the event the other gets filled with smoke seen as a major driver for the requirement.

It said: 鈥淭he department is concerned that some tall residential buildings are being designed with a single staircase without due consideration by the designers on the level of safety provided and the necessary resilience.鈥�

As far back as 2018 the RIBA said in its response to the Hackitt report that all high-rise buildings should have more than one means of escape 鈥� with the architects鈥� body at the time recommending a second stairwell be required in 11m buildings or higher. Just last summer it criticised the government for confusion over the issue. In December the National Fire Chiefs Council called for all buildings above 18m in height to have the same requirement.

The department鈥檚 consultation said the 10-year cost to business would rise to 拢3.7bn if it had implemented the requirement at 11m-plus, or 拢2.5bn for 18m-plus.

The move comes after developer Ballymore last year pulled plans for a 52-storey tower in London鈥檚 Docklands and later redesigned it with a second stairwell following pressure from campaigners and the London Fire Brigade over the issue

The same consultation also proposed a number of other significant changes to the system for fire safety regulation, proposing to mandate sprinkler systems in care homes at all heights, and to finally remove all references to the old British Standard national product classification system from building regulations 鈥� known as the BS476 series.

This is the system, long ago supposed to have been superseded by the European products regulation system but was never formally removed from the regulations, which contained the 鈥渃lass 0鈥� rating which caused much confusion in the approved documents. A Class 0 rating only refers to the surface of a product being of limited combustibility, while the internal composition of the product can remain flammable.

In addition, the consultation, which will run until 17 March, is consulting on potential amendments to the wording of the key paragraphs in the Approved Documents guidance covering the make-up of external walls on high-rises 鈥� paragraphs 10.6 and 10.7.
