Loft and Basement Conversions

If you’re looking to extend your property upwards, it’s vital to add a fire suppression system to your property to help protect yourself and your family in the event of a fire. Building regulations cover fire legislation to ensure that properties are effectively covered in the event of a fire.

The increased eaves and height of a property should be noted, especially when in regard to escape routes and fire safety. Properties over 4.5m should allow a protected staircase to allow for a safe escape route. If you’re looking to have an open plan living space, a fire suppression system is highly recommended to prevent the potential spread of any fires.

When do I need a fire suppression system?

BS 9991 says you must have an AWFSS in the following circumstances;

5.2.1.2 Multi-Basement Buildings

For dwellings with multiple floors below ground level, a protected stairway, and an AWFSS, 9m meters should not be exceeded for from the foot of the protected stair to any habitable room.

6.4 (b) Dwelling Houses with one or more storey greater than 7.5m in height (4 storeys)

A second, separate protected stairwell is not required if AWFSS is fitted throughout.

6.5.2 Loft Conversions 

Open plan arrangements on the ground floor are permissible should AWFSS be installed throughout, in conjunction with a fire resisting partition and door at the first floor level.

9.7 Open Plan Layouts

Open planned flats are permissible with a fully fitted AWFSS

Loft Conversion Case Study

Through one of our many returning contractors we received an enquiry to retro fit our system to the ground floor of a project receiving a loft conversion. Additionally, the customer wanted the system upgraded with an SMS system to receive text updates for an activation, loss of power, service due, etc.

The project was installed swiftly and meant the end-user could keep the open plan downstairs living area, and achieving the loft conversion.
