when looking at the structure of my building, I have looked at each layer of the building in terms of a grid structure, as well as the bracing for the windows.

For the roof structure, I have taken a slightly different approach than a typical grid structure, using the peaks and valleys of the undulation and the outline of the roof offsetted for the grid.

for the windows, I have used a 2.5 span for the bracing stucture around the perimeter of the building in a triple glazed structure.

Here, I have exploded the overall structure of the building to show all the components. As shown on the left, I have used a 8x8m grid structure for all the floors. I need to look at how this connects with the roof structure.

This maquette, built at a 1:5 scale, helps us understand the materials used for the facade and floor. It focuses on three main components: the wooden strips, the glass wall, and the floor build up. The wooden strips are connected to the glass wall using metal fixtures that hold them in place. These fixtures are attached to the upper floor, providing support from above. The glass supports, located on the upper floor, add extra strength to the structure. By studying this model, we can see how the wood, glass, and metal work together to create a strong and attractive facade for the building.

Firstly, the existing site will be demolished and prepared for building.

Secondly, the ground will be dug out for the lower level of the ground floor, and an in situ concrete floor plate will be layed out.

Lastly, services, landscaping and lighting as well as other ornamentations will be put in place. Trees will be imported from local tree farms to minimise carbon emissions.

Thirdly, the primary steel structure will be prefabricated and delivered to site where it will be put in place using cranes.

After this, stair wells, lift shafts and floor plates will be casted on site.

After this, the timber lamella facade, glazing and bracing will be put in place. Then, the roof and roof structure will be put in place, with panels prefabricated and then transported to the site.

- the front area and back area has a width of 5m to accomodate fire vehicles carrying a large tonnage

- Revolving doors do not act as fire escapes so a further fire escape is placed near the entrances

- 18m escape routes for disabilities, but fire escapes have been reduced, following advice from a fire engineer that companies would not pay for this many fire escapes

- accesible toilets measuring over 1600 x 2200mm, accessible toilets have seperate entrances wheelchair lift

- ramps will be a 1:20 gradient and under 8 metres long

Fire, Approved Doc B Stairs Lifts Toilets Ramps

- railing will be set at 1100m

- stairs provided on each storey, with direct access to the stair with minimum size of 900mmx1400mm

- spiral public stairs for use by large numbers of people at one time and used in places of public assembly should be a minimum 150mm rise per tread, and a minimum width of 1000mm

- for escape pruposes, every part of each storey should have access to more than one stair

- staircases and lifts will allow firefighters to access the lower level

- materials that have been chosen are aimed for longer structural integrity, giving users more time to escape and comply with the regulations

- all lifts have been transformed into evacuation lifts, compliant with BS59999 and BS9991 and are over 1100mm wide and 1400mm deep

- each space will be connected to their own sprinkler system, as well as fire detection system, Therebye detetcing a fire when it starts to spread, it can contain the fire longer from within and attempt to extinguish it right at the roof.
