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.

Brief

Beauvais is a small French city at the outskirts of Paris in Northern France. The city has 60.000 population however it hosts the most ambitious gothic cathedral ever built with the highest vault by 48m. The cathedral is incomplete due to the collapse of its 153m central tower in 1570.

The city's growth pace is not likely to change in the next decade. Although the city's airport, Beauvais Tille is becoming important for the use of Paris visitors. Ryan Air and other European economy airlines use this airport for the passengers of Disneyland and Paris.

Our cities today are defined by destinations instead of their whole urban identities. Bilbao is Guggenheim, Sydney is the Opera House, London is Swiss-Re, New York was the World Trade Center. Beauvais already has its own icon that is built with extreme craftsmanship and care. Partially renovated by Viollet de Luc but his proposal for the completion of the nave was never got to realization stage.

What makes Beauvais Cathedral very interesting for me is this building is not a touristic destination. Only in lunch time in a weekday the restaurants around the cathedral are packed with people and when it's work hours the cathedral and it's surroundings are empty.

My proposal is about taking advantage of this attention free, lonely icon, turning it into an icon used 24/7 by the city itself instead of aiming for the attention of the people around the world. A selfish use of the great interior and exterior of the cathedral for the city itself instead of a potential audience from Chile, Japan or Australia. Iconic architecture should not be aiming to become still image in handy-cams, ready for consumption; it has to be truly part of the city life it belongs to, similar to the HSBC building in Hong Kong.

The gothic cathedrals were designed for the breath taking experience of the interior with highest vaults that can ever be achieved without any structural interruption, with very controlled daylight entering into the space. However this ambition became reality without the technology we have today therefore Beauvais Cathedral will be collapsing in about ten years of time as it is predicted by Columbia University in New York. Beauvais Cathedral is surviving from this structural weakness with the temporary timber supports built inside.

My proposal will be allowing the removal of these supports in order to fully experience the interior. The project evolved around the exercises as response to the seven chapters from "Seven Lamps of Architecture" book by John Ruskin.

Mont Beauvais

The project is a lightweight structural web wrapping around the Beauvais Cathedral, supporting the Cathedral; aligned to the existing flying buttresses as extensions. While doing this, this lightweight web also hosts sequence of spaces to create a compact city around the Beauvais Cathedral just like how cities are attached to the cathedrals in Mont Saint Michel, Laon in France.

Just like how the gothic cathedrals were taking the nature: skeleton structures as their precedents, the project aims to have the same approach by forming a building with columns and arches. Supporting churches with building new extensions has been happening throughout the history just like how Sinan built buttressing for Hagia Sophia's dome and the scaffolding that was removed 2010, stayed inside the building for 17 years supporting the dome for the restoration work.

Thesis

Completing a major cathedral like Beauvais is not a similar task to completing Notre Dame of Paris or Reims as if they were left incomplete in the middle of a major metropolis of France. The city has a population of 60.000 and it is not likely to increase in the near future. Cars are dominant at the city center, population is not young. One important aspect of the city is presence of the Beauvais Tille Airport. The airport is used increasingly by the travellers of Paris and Disneyland. Shuttle and train services are supporting the airport. As a city, the expectation of Beauvais become Bilbao by the power of one building is unnecessary and unrealistic. However such a beautiful building the left alone, incomplete in the middle of this village like city is tragic too. It should be recognised there is a reason the most ambitious gothic cathedral ever built is incomplete and it is mainly related to the financial and cultural weakness of the city Beauvais.

Turning the Beauvais Cathedral politely into a sparkling diamond having no dramatic impact on the city life would be an elegant restoration work. What should happen with such a great interior space is, it should expand, break the ground and conquer only to become part of the city again without any banal statements against the religion. Preserving itself as a Cathedral, a new world can be built around it to prove the power of the building again.

Urban Thesis

Our world today is not about the city, it is about buildings, it is either about the free standing - object like buildings or ugly and mega buildings providing infrastructure themselves. If this is the rule of the game, we can only manipulate and shock, to prove a building can do more than being a pretty sterile background image, a wallpaper.

Like Mont Saint Michel, like Laon Cathedral of France, Beauvais has to expand has its own city around it engaging 24/7 with itself instead of being alone. The completion is not a physical addition, completion is the bridging of Beauvais with it's people. It’s a soft transitional frame providing great spaces between the spectacular interior of the cathedral and the slow city of Beauvais.

This transitional space must be heavy looking like a mountain however when it is experienced as a space should be very light looking as a structure. The observer must be surprised in the city seeing at certain angles building becomes almost transparent similar to the experience of Reims Cathedral’s facade.

Mont Saint Michel of France is a city built around a church located at the highest of a rock. Since Beauvais has the most ambitions of height among other Gothic cathedrals, the idea is to treat the incomplete cathedral as an origin for a mountain city opening into the great interior.

Technique

Nave is the incomplete part of the cathedral, therefore the proposal starts with the line completing half of the roof for the nave. Then this nave reaches the ground level descending while rotating around the cathedral taking the transept as the origin. The lines, like a spider web are connected to each other forming spaces independent from the interior of the cathedral,
