MATERIAL JUNCTION

With the aim to provide a historic facade with a modernized look, the vertical extension is clad in corrugated steel. Therefore, a material junction of old-new material is analysed to interrogate the interconnection between to and develop a strategy of insulation application on the inner face.

Insulation of the MWR walls is critical for sustainability and financial stability. The current structural wall is not insulated which is a cause for structural damage, mould etc. The additional layer of insulation ensures that the building is up to standard with goals for sustainability in the UK.

Fire safety is one of the largest concerns (For analysis of current, Phase 2 refer to the integrated booklet). Because the vertical circulation elements are placed on opposite corners of the building the fire escape distances from any given point on a floor are relatively similar. The major concern; however, is escape distances from the 2nd and 3rd floors. On the 2nd floor, a balcony extension is added to ensure that there are 2 directions of escape. On the 3rd floor, the overall cumulative distance of going down 3 floors is concerning at certain points of the proposal. For this reason, I am suggesting that an external fire escape might be added to the structure (marked with a cross). This would help shorten escape distances from the centre of the room.
