PROJECT BRIEF

1:500 site model
Correlation between Carpenters’ Hall and the neighbouring building
- extension of the Carpenters’s Hall will take 30% of the volume of the neighbouring building, however the volume does not fit the existing building, thus space for Analysis study in Mathematics is given to partnership building. - 50% of the extension will be used as the Mathematical laboratory for Applied Mathematics - 30% of the extension will be used as the public living space - 20% of the extension will be used as the private living for MT during weekends
Site Analysi
SOURCES OF SOUND
3
ACOUSTICS
- transport in London such as bus, private cars and taxi produce the most noise to the area - bikes and pedestrian also contribute to the noise
PREVAILING WIND
- prevailing wind has an impact to the building since the extension of the new building does not encounter any obstruction from the nearby building. - the prevailing winds can be used to ventilate the building. - the overall prevailing wind direction is west-southwesterly.
WIND
TEMPERATURE & RAINFALL
-average highest temperature: 23oC (July & August) -average lowest temperature: 9oC (January & December) -highest rainfall days: 23 (January) -lowest rainfall days: 15 (June)
Su
mm er
SOLAR PATH
- temperature of the workrooms should normally be at least 16oC or 13oC if much of the work is physical. - attempt to collect rainfall since there are great number of rainy days in a month.
Lon do nW al l
SOLAR PATH
- the orientation of the sun produces more exposure to the south side of the building - the extension of the building receives more sunlight as compared to the rest of the building surrounding

PROPORTION OF THE BUILDING
- due to the shaded street , the height of the new building is taken into consideration - y = 6 metres - colonnade is measured to be y = 6 metres - piano nobile is measured to be 2y = 12 metres - the extension of the building is proposed to be 12 metres including the third and fourth floor of the existing building.

extension of the verticality of the columns the vertical elements continue to serve as the structure for the new extension From the plans provided by London Planning Department, it is known that the columns on the facade does not serve as the structure.
bringing the balustrade to the top of the existing building redesigning and position the window facing Throgmorton Avenue to align with the proportion of the facade to give the building a stable condition extending the existing columns towards the edge of the fourth floor the columns do not need to extend towards the top edge of mathematical lab since the proportion of the existing building is stable in square form.

- idea development - removing the structural columns, further investigation on the sizes and volumes of the Mathematical lab - ‘the city disappears at the horizon’ - Smooth journey coming from the Blomfield Street towards the Carpenters’ Hall along the London Wall - The project has a direct relationship with the neighbouring partnership building across the London Wall.

Insulation
Mineral wool insulation is located in between the secondary joists that run across the primary glulam beams. It also provides additional insulation to the existing building.
Foundation
The grillage provide a flat foundation for the new building to create the new structural grid. Using the cross laminated timber, the load is carried down to the grillage evenly throughout the building.

a sanctuary to escape the bustling city the private living is access through the grand staircase which leads to the dining hall

Precedent_St. Paul’s Geometric staircase
Cathedral_
The treads of the geometric staircase are set only 150mm into the wall, then float out into the air. Their ingenious construction allows these elegant, almost ethereal spirals to provide a firm, secure staircase which has served already for three centuries. Officially known as the Dean’s Staircase, the broad spiral gained its ‘geometric’ nickname thanks to its extraordinary character. Each of the 88 stone treads rising from the floor of the south-west tower to the triforium level is set into the wall and carefully shaped to rest on the one below; there is no other support.
