LOGO - THE PARLIAMENT STEPS

I have started working on a logo to help communicate my design idea clearly during the presentation. After tossing up between a few different names, I have decided to call my project THE PARLIAMENT STEPS.

The colour green lends itself to this project so I will keep the logo very simple and use a bold green which I can incorporate into my panels also. After a few attempts at the logo, the one I am happiest with is the following:

The logo will have 2 different forms. The predominantly green one I will use to introduce the project and the other I will use as a watermark on the rest of the panels.

ROOF STRUCTURE

Originally I wanted to create a space with as authentic an outdoor feel as possible, so the idea of a roof doesn't overly appeal to me. However in the Brisbane climate shade cover will be an important issue, otherwise the steps will no doubt be under utilised during the middle of the day and afternoon when the sun is at its hottest.

I am visioning the steps being utilised as a meeting place and a social place during the day, during office lunch breaks for some and breaks from exercise routines for others. For this reason then it is important that I incorporate a shading roof cover.

As I still want an open air feel to retain the outdoor quality of the space I will propose a roof cover which is as open as possible and does not cover the whole structure. I believe it will provide protection from the sun without feeling enclosed or separated from the surrounding natural environment. I am proposing timber battons, supported by steel columns, and in the shape of a palm leaf, a tree that is found throughout the whole of the botanic gardens. The steel will be minimal and the timber will be the dominant material, sensitive to the surrounding environment in the gardens. It has a warm feel and ties in with the timber of the rotunda structure located between the stirs and the Albert St entrance.

I experimented with some timber pieces to determine the feel I could get from different shapes in the timber before deciding on the final form for the roof (see final panels for drawings).

DEVELOPMENT AND MODEL

My design is getting to a stage now where I am ready to start documenting. There are still some details I am unsure about. They are mainly issues to do with structure and also related to integrating services into the stair.

STRUCTURE:

To support the cantilever structure, I have assumed a deep system foundation that extends from the foot of the steps to the back of the storage room underneath the steps. This should allow a secure base to fix the structure down into the earth. Two large columns form the frame of the cantilever and extend down alongside the steps and into the foundations also. These columns would be post tensioned concrete.

It is assumed that the steps could be cast in modules in a lock and key fashion so as to hold fast in place and supported with steel beams. The concrete modules would also be post tensioned concrete and be cast with the necessary conduits to allow the integration of services.

SERVICES:

• The facility would require electricity and hydraulic services as well as the following services integrated into the construction:

• Conduit for LED lighting strips to run along the underside of the concrete seating steps to light the 'aisles'.

• Drainage from the lowest point in the grass bed concrete stair modules down to the base of the structure.

• Mechanical services to rise and lower the grid panel for reconfiguration of space.

The model I made allowed me to resolve the remaining space and circulation issues:

DEVELOPMENT

Now that I have made a decision on my design concept and function, the development is travelling relatively quickly. I have a good idea of how I would like the space to work but I am getting stuck on the structure and also on choosing a site. I wanted to locate the design in the Queen Victoria Park in the centre of the city due to its central location and vicinity to the constant action and activity of the city. I never noticed before that there is a giant carpark beneath this park. And as I have also been looking at the structure of the staircase and would like to create a cantilever structure, this will not work. I'm not sure structurally what the cantilever would require but I think the design I am working on would be best cast in concrete and post tensioned and would also require some sort of deep foundation system to counteract the moment created by the cantilever.

I have started a model to test out the overall shape and aesthetic which I would like to achieve in the design. I also uses it to test a variety of seating angles. It worked very effectively. I very quickly got an idea of how the different seating would affect the overall look and feel of the design which made the design very easy to make.

ACCESSIBILITY

It is important to me that the proposed space never closes. A parliament for the people should offer qa space which is always accessible and available. This will be possible for me to do as I would like to integrate it as part of the park, so that when it is not being used for a specific function, it is merely a part of the park for people to enjoy. It is also an important consideration to design a space which can be accessed by persons with disabilities also.

SITES

To effectively distribute this design across Australia I am proposing that each of the Capital cities host a Parliament stair. Upon looking at each of these cities and the planning it was relatively simple to pinpoint and suggest appropriate sites that met the following requirements:

• Located in the central activity hub of the city
• Located close to the parliament house of the city
• Located in an areas of public parkland/ green space with enough space to create sufficient circulation routes to from, and around the stair

The locations I am proposing for each of the cities are:

(The existing parliament house is shown as a dark square. The proposed parliament stair is shown as a green circle)

For this project, I will develop the Brisbane site further to work out the issues with access and circulation.The selected site in Brisbane is in the place of a current rose garden in the Brisbane Botanic Gardens. The main reasons I chose this site to house the Brisbane parliament stairs are:

• It is central in the CBD yet sheltered enough that traffic noise will not be an issue

• there is plenty of space to develop on this site.

• It is on the axis connecting public places in the city. This is significant as this design proposal is about creating a space FOR the people.

• There is excellent access to the site by all persons. It is accessed through one of the main entrances to the Botanical gardens, off Albert St. The circulation paths are wide and suitable for persons with a wheelchair also. There are no steep inclines to get to the site from the entrance. It is easily located and will be visible from Albert St.

• The existing rose garden is continually being replanted so it is proposed that this cycle of planting simply be relocated to another area in the gardens to retain the display of roses in the gardens.
