Original massing concepts involving a large wall to the north that reflects indirect sunlight into the complex.

Once developed as a sketch I used it to design a massing model.

Original design for the centre chamber and a redesign of the form to incorporate 11 “arms” which would house the essential rooms for each LEP.

The dedicated public/private interaction space where members of the community can talk to members of their respective LEPs and discuss legislation, worries, or ask for clarification of certain matters.

Design for the central debate chamber, involving public seating to watch as events unfold, an antechamber where the members debating can mingle, socialise, and relaxing before and after meetings.

Eventually I developed a form of two buildings site by side, that portrayed the interaction of public and private sectors through their symmetry and asymmetry, as well as adhering to the programme.

I began to play with ideas of splitting the building into two sections to more accurately follow my programmatic diagram, and played with ideas of placing the buildings across the dock itself. I also began to consider some details, such as making the ground floor a vaulted ceiling to hark back to the warehouse that once occupied the site.

Technical Structural Structurally, my building relies mainly on loading bearing reinforced concrete walls in order to support itself. Due to the ground floor being comprised of either barrels or vaults in both buildings, the floors are entirely structural being able to distribute the load evenly to the foundations.

The debating chamber of the Private Building is an environment that needs to be carefully controlled, as it will house many people who could be sitting within the chamber for extended periods of time. The comfort of the occupants must be optimal otherwise the debating process will suffer as a result. The main factors that need to be controlled are: . Ventilation . Humidity . Temperature These factors are all controlled through the same system, air conditioning, therefore this needs to be optimally balanced to deliver a positive experience within the chamber.

This is the main structure of my building, being load bearing reinforced concrete. The domes are also reinforced concrete, yet much thinner as the domed shape doesn’t need as much support.

However as the dome on the debating chamber of the Private Building doesn’t have a solid surface for the load to distribute to (like on the Public Building) it requires flying buttresses to carry the load to the ground.

The foundations of the building are mainly concrete pad foundations, as the buildings weight is distributed through lots of smaller points. There are some areas supported by raft foundations (the stairway towers in the Private Building offices) however this is in the minority.

Ventilation Ventilation can be managed in two different ways, natural and artificial. Natural ventilation is often much cheaper as it requires very little running costs, and is also much more environmentally friendly due to the lack of machinery involved in the process. However, it is much harder to control natural ventilation and oftentimes due to the nature of the UK’s dramatic climate it can result in negative impacts, for example temperatures can be at 20c and sunny one day and then fall to 5c and cloudy the next, leaving a building cold as it was functioning in a warmer setup.

Artificial ventilation is much better at adapting to sudden changes in climate, with it being able to heat up a building much faster and more reliably than natural ventilation. Furthermore it is able to regulate and maintain certain values, allowing the building to be at a constant temperature and humidity throughout the day and into the night, where natural ventilation would cause the building to cool. Unfortunately these advantages do come at a cost as artificial ventilation has a much higher energy demand, with it adding an estimated 50% to the total energy cost. Alongside the price, artificial ventilation also has a much higher environmental impact as the production and usage of air conditioning leads to higher CO2 levels.

Lastly this section is subterranean and therefore needs to be constructed using reinforced concrete retaining walls. These walls allow for the lowered areas to resist the loads of the ground and to remain in place.

Detail As I have designed my building to have a concrete exterior as well as interior, I have had to design my section with that in mind. This is a section of my building displaying the roof, wall and window arrangement, and an interior floor/ceiling.

Site/Project Plan 1:500 and Water Levels Since a large part of my concept involves the rising seas I looked at the IPCC’s (Intergovernmental Panel on Climate Change) reports on climate change and found that their research projects that global sea levels could rise between 0.43m and 0.84, with an upper range of 1.10m by2100.

Current Low Tide IPCC Predicted Low Tide (+430mm) IPCC Predicted Low Tide (+1100m)

Current Highest Tide (¬10,000mm) IPCC Predicted High Tide (+430mm) IPCC Predicted High Tide 10 (+1100mm)

Due to the nature of the building, it contains many different structural forms that resist forces from all angles to keep the building stable.

The LIME highlights the subterranean structure that is made up of reinforced concrete as it effective acts as one large retaining wall.

The RED structure is directly supported by the large piles that reach down into the earth, allowing this part of the structure to appear to float, however due to the makeup of the ground at this site, the might need to run deeper than they currently do.

The Drainage Room and Oculus Room act as both the main contemplative space, the main entrance into the building, and the focal point of the thematic concept, as this is where water flows in and out of the building.

The Library contains literature regrading The North Wing contains a social space climate change and how it will affect life for those visiting the building, as well as in every way, including research views into the forest, and of the Mersey. published by those who work in the building, as a place to educate those visiting.

The Café is a space where all residents of the building (scientists and the general public) can purchase food and drinks if desired.

The Lecture Hall acts as a lecture space when the chairs are laid out and blackout curtains can be drawn across the glass in order to focus the room, and a social space where views of the Mersey and the forest are available to those using the steps as seating.

The BLUE structure is placed upon a raft foundation due to the unstable nature of the ground at my site, as the entire site is artificial land made up of mostly landfill, the raft foundation is suitable as it provides a wide surface area for the structure to sit stably upon.

The CYAN structure contains a truss structure that supports the social wing of the design, this structure allows this part of the building to float above the ground without need for extra supports.

The Lab is the only place within the building that is not publicly available, as it houses the scientists, their equipment, and their research.
