INTRODUCTION
This project is for alterations and additions to the existing Wayside Chapel in Hughes St in Potts Point. The proposal is for the redevelopment of the existing site. The core buildings are retained and two currently dilapidated buildings are demolished and rebuilt at an increased size to allow for better space and energy efficiencies and an increase in the availability of the cultural, charitable and community services currently provided.

THE WAYSIDE CHAPEL
The Wayside Chapel was founded in 1964 by the Rev. Ted Noffs. It has been a vital part of life in Kings Cross and Potts Point since its foundation, and offers a small chapel as refuge in the heart of this very busy area. In addition to the chapel itself the centre provides drug and alcohol counselling, a crisis centre, a coffee shop (used as a drop in centre), a bathhouse for homeless people, and houses the offices for a number of social services including a youth team and the national and local Life Education officers. For many years the centre offered a public theatre which was used by local theatre companies for productions, however this has been closed for 18 months due to the state of the existing building. There is also an op-shop called Wayside Creations which has operated out of various buildings and is currently housed at the western end of the site.

DESIGN CONCEPT
The site is on the corner of Hughes St and Orwell Lane and has an area of 694 square metres. It currently houses four interconnected buildings. This design concept is for the demolition of the western two-storey terrace house, and the rear theatre, and the construction of a new five-level building in an L-plan shape to replace those two buildings. In addition, renovations would be made to the existing chapel, and the existing coffee-shop and offices building, to interconnect the buildings so that there is public circulation across all three buildings allowing for a better organisation pattern for the entire Wayside Chapel Centre. The arrangement of uses of the building will remain substantially the same, with the retained two buildings continuing in their existing uses.

NEW BUILDING
With the demolition of the 2 storey building terrace building and existing theatre, the possibility arises for the construction of a wholly new building which will form the backbone of the new centre. It is proposed that this building be built out to the street frontage to provide a more obvious point of entry into the building, to provide closure to the outdoor space, and to provide a building in front of the existing expansive east-facing brick wall of the adjacent four storey apartment block.

PLAN
The new 5 level building has a lift and fire-stair at its core, and provides spaces of public access on the lower levels, rising to more private spaces for the use of Wayside Chapel staff on the next two levels with a manse for the Reverend and family on the 5th level. The ground level provides public access through an airlock to provide thermal isolation between inside and outside, and to allow a "meet and greet" space. A large foyer space is provided since the Chapel often has large groups visiting, and this foyer would also act as the foyer space to the meeting rooms and small theatre on level 2.

BUILT FORM
The materials and construction of the new building will be in a contemporary style, but complimentary to the existing structures. The new building will be in the form of rendered masonry, so as to avoid a clash of brick colours, and to distinguish the old from the new, and to allow for this building to be painted a relatively mid to dark colour to be recessive in its bulk. The fenestration patterns to this building have larger windows which are deeply recessed into the masonry with louvres to control sunlight penetration. At the street edge and the eastern face the openings are smaller in shape and size commensurate with the windows in the windows in the adjacent and opposite apartment buildings.

STREETSCAPE
The DA proposes the retention of the prominent corner building and the adjacent Chapel building, substantially retained in their existing form and height. The external walls and fenestration would be retained and repaired with the existing face brickwork and painted render retained and upgraded. The only change to the building at this point would be the removal of the rear roof with its extension up to provide additional space together with the requisite service space and support for the solar panels at the roof level. In this way the existing streetscape and appearance of the building is substantially retained, particularly in its view from McLeay Street, down Hughes St to this prominent local site.


SUSTAINABLE DESIGN

It is intended that this new development for the Wayside Chapel achieve best practise in Environmentally Sustainable Design (ESD). This will be achieved through the adoption of passive principles, as well as active systems to improve internal amenity, comfort levels, and reduce energy consumption.

Sustainable design - passive systems
The Wayside Chapel Centre has been designed to take advantage of state of the art sustainable design systems to lower energy and water usage. The energy for air-conditioning is greatly reduced by the use of cross-flow lateral ventilation in the meeting rooms and office areas and in the manse. The original east building continues to rely on natural ventilation as it was originally designed. The offices are fitted with louvered windows on both sides and are provided with mechanically assisted stack ventilation system to assist on still days for there to be natural ventilation across the offices and ducted up to the roof. The manse is designed with similar louvre systems and has cross ventilation assisted by stack ventilation along the central double loaded corridor.

HVAC systems
Two critical spaces within the centre are air conditioned: the original chapel and the theatre as these spaces are fully enclosed and are often highly occupied to a level that would not be comfortably cooled with cross ventilation. The air-conditioning system is a split system with condensers in the service towers on either side of the roof space.

Photovoltaic (PV) Cells
The roof has photovoltaic cells mounted and oriented towards the north to provide backup electrical energy to the building. It is intended that the PV cells will be connected to the main grid to lower the energy demand of the building as a whole. It will also be investigated as to whether these cells may provide a backup in cases of power failure.

The building will be wired for intelligent systems using a main computer server for communications and video. The building will also be fitted with a closed circuit TV system to allow monitoring of the outside area from the main office and the caretakers office and the manse.

Lighting systems
The design of the building seeks to maximise natural daylight to all spaces as much as possible (except for the Theatre). This is achieved by large windows to the north (fitted with adjustable louvres as outlined above) and large areas of unshaded windows to the south. Some windows are included on the east elevation of the new building, and these are fitted with "light shelf technology" in the office spaces to extend the light into the internal areas of the offices.

The artificial lighting systems will be based on the use of Electronic transformer based T8 fluorescent light fittings to dramatically reduce demand over conventional incandescent lights. All lights will be controlled with "smart technology" using sensor controlled automation for reduced usage (e.g. automatic switch off when space is not in use).

Water cycle.
The demand on water resources by the Wayside Centre is greatly reduced by both reducing demand-side management and by adopting collection and recycling strategies to minimise fresh water requirements. All new fittings within the building will be AAA rated to have flow limited to 6L per minute for basins, 9L per minute for showers and 6/3 flush toilets. This represents current Australian best practise for minimising the amount of water required at the point of use.

Rainwater will be collected from the roofs and stored in a water tank beneath the op-shop area for use throughout the building. The water will be filtered through charcoal filters and purified with UV filters prior to being delivered to all outlets within the building. This will be supplemented from a mains supply fitted with the requisite one-way valve.

It is proposed to dispose of toilet waste directly to the sewer, and the grey water from showers and basins will be stored in a grey-water tank on site, adjacent to the freshwater, for recycling through the toilet systems and for use in the transpiration beds and landscape areas on the roof garden and at the front of the building. It is intended that these systems will be designed in conjunction with the Institute for Sustainable Features Water Team (Stewart White, Director).

Waste management
The buildings will be demolished and rebuilt using current best practise for construction waste management as outlined by the Waste Boards Program for demolition and construction. In particular, as the materials from the existing buildings will be recycled where possible, reusing the bricks from the old lime-mortar walls. The current asbestos cement roof will be disposed of in the approved manner. The design of the building contains a large number of prefabricated components (floor beams, window panels, external cladding panels, louvre systems, internal fitout items) in order to minimise onsite construction waste
