Working on the Brief



centre for the building is consciously shifted 
Unquestionably the transept is the centre in the gothic cathedral. In a secular extension, this centre of the crossing is deliberately ignored and the centre point for the ambulatory is taken as the centre of the building.

new entrance to Basse Oevre 
The radius of 60m allows the extension to meet the opening/demolished roof section at the south east of the old church to be replaced by Beauvais cathedral which can also become an alternative entrance.

dividing the mass into three general levels 
The cathedral is 60m high including the roof. Divided into 4m levels, it becomes 15 levels for the extension. First 6 levels reach the level of triforium. This section requires to be the structural base for the rest of the extension. Next 6 is sandwiched between the start of the roof and the end of the first 6 levels.

facade density in terms of rings 
Facades will become denser as moving outwards in plan, since apartments are located at the outer rings, privacy will be provided by this rule. The inner rings require to let the maximum amount of light into the cathedral therefore sparser structure right next to the cathedral would be the right decision.

new west facade is a hologram screen 
Facade of the cathedral is always used for communicating the christianity with the public. Statues of Jesus, French kings, bishops, stories from Bible are all located around the entrances at the west, south and north, but mainly on west facades. Although the extension has a secular programme, the west facade include messages for the public through hologram technique.

replacing the temporary supports
The new system will be replacing the existing supports between the flying buttresses. Also the timber supports in the transept will be removed.
