We advised the client to use fire curtains to allow for an open plan design whilst ensuring there was a protected route in the event of a fire.
With the orientation of the kitchen a small wall had to be designed into the plan, however, this had little effect on the open plan nature of the flat as possible with the larger portion of the protected exit being formed by a fire curtain that would deploy in the event of a fire.
To allow for a basement an alternative escape route was introduced into the design, similar issues also had to be solved for the buildings on the upper floors with an escape window being installed to allow escape from the top floor.
