HISTORY
Introduction Brownhill Creek is valued by the community as a unique cultural landscape and an important natural environment. It is of great significance to the first inhabitants, the Kaurna people who named it ‘Wirraparinga’ – place of scrub and creek. One of the first settlers in the area, Pastor William Finlayson observed up to 150 indigenous people camping in the area at one time.

The Brownhill Creek Reserve, a 3.5 kilometre linear strip of land either side of the creek, was set aside by the South Australian Government in 1841 as a “Reserve for Public Purposes”, making it one of the oldest public reserves in Australia. On 15 July 1915 Brownhill Creek was proclaimed a “National Pleasure Resort” under the control of the South Australian Tourist Bureau. It remains a very popular recreation place to this day.
HISTORY
VEGETATION
Vegatation and Animal Species A wide variety of floral and fauna can be found can be found across the entire site in Brown Hill Creek. The site itself is filled with native and non-native floral, trees and creepers species. A detailed list of all the species can be found on the Brown Hill Creek Website.
Koala
From native species like the native apricot and native wheatgrass to non-native florals like the white goodenia and even trees like the river red gum are the few species that can be found on site. The site is a natural wildlife corridor that houses over 40 species of birds and mammals like the kookaburras, bats, water rats, eastern brown snakes and even koalas. The nationally endangered southern brown bandicoot can also bee found at the site.

Site
Circulation (Traffic and Creek)
The site is located in the inner south suburbs of Adelaide metropolitan area. It is a 30 minutes drive from the city and almost an hour ride via public transport.
Legend: Creek
Brown Hill Creek is also part of the Patawalonga River catchment.
Being part of the Patawalonga River cathement, a creek also cuts across the site.
Main Road
There’s only 1 main two way road that runs across the site.

Circulation (Trails)
Topography
Trail 1- An easy walk with some gentle slopes. Distance approximately 3 kilometres. Time taken approximately 1 hour.
The site varries in height when it comes to the topography. Where the actual loacation for the treehouse is located, the ground is on the same level as the main road. However, the topography rises on both sides of the treehouse loacation.
Trail 2- An easy walk along the Wirraparinga walking trail and on the side of a sealed road with some gentle slopes. The path switches from one side of the road to the other, but is clearly signed. Distance: 6.5 kilometres. Time: Round trip 1.5 hours (at a brisk pace).

TYPOLOGY
Chosen Tree/s The chosen location as to where I’ll place my treehouse has 3 trees in the area. With the placement of the trees, it gives off a triangular formation creating a wide open space in the middle. The trees are placed at an angle where it faces north, allowimg sunlight to enter which is crucial in winter but it’s still pretty shaded which is useful to block off the summer sun.
Treehouse Typology For the typology of the treehouse, 2 types were created. Type 1 made full use of how the trees are placed and the open area that was created. With the open space that’s available, the treehouse will be place in the middle while being supported by all 3 trees. This placement allows the treehouse to take in maximum sunlight. Type 2 uses the tree that is in the middle for the treehouse. The entire structure and form of the the treehouse would “wrap” around the tree. With the chosen tree being placed further back than the other 2 trees, the treehouse would be shaded hence being pretty cool during summer. Though it is more shaded at the back, with how the trees are placed at an angle, sunlight is still able to penetrate and heat up the area at the back hence the location would not raise an issue during winter.

DESIGN CONCEPT
Concept and Form The concept and form for the treehouse was derived from taking elements that can be found in nature. Being on site, the inspiration came when I was among shrubs that blooms flowers and bees were spotted. Another prominent element was, birds were constanly chirping in the background. Hence I decided to base my design on these two elements. Bird nest
Being inspired from bird nest, I wanted the “walls� of the tree house to have a similar weaving effect to give off a rustic yet natural look to the treehouse. Beehive was the main inspiration of how the form of the treehouse came about. By changing the form of the curvilinier beehive to a more angular structure, the basic form was created. From there, the form was further disect into half creating a honeycomb shape. The form than took its final shape with the design being build from there.
Beehive
The treehouse is split into two sections, allowing the user to travel up and down; enjoying different views and vistas that is provided at different heights.

DESIGN CONCEPT
Form: Derive from the beehive curvilinier shape; has been tweaked to a more angular form.
Form: From the basic shape, the form has been further developed. Walls incorperated the weaving effect that can be found with birdnest.

STRUCTURE
Structure The entire main structure system primarly uses timber as the primary material. A simple construction method and structural system is being implemented as well. To keep the overall look minimal, the design for structural system is kept simple so that the structural elements does not overwhelm the treehouse.

Timber Columns
The overall structure of the treehouse is made out of timber.
The main structure that is holding up the treehouse are columns. 2 different heights are provide for the columns to accomadate the height differance in the treehouse design.

Timber Joist
Dovetail Joint
Another main structure that holds up the treehouse are the timber joist that runs across base/floors of the treehouse.
A construction detail that the treehouse has is each wooden plank that is used as the floor and ceiling are connected through a dovetail joint.
