INTRODUCTION 5
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.
B R O W N HILL CREEK
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.

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).

DESIGN CONCEPT 11
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.
12
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.

TYPOLOGY
DESIGN CONCEPT
Concept and Form Bird nest
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. 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.
14
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.

Basic form
Basic Form: Derive from the beehive curvilinier shape, the form has been tweaked to a more angular shape to give a modern twist to it.
Form: From the basic shape, the form has been further developed creating a more angular strcucture. The exterior facade incorperated the weaving effect that can be found with birdnest.
Details:
Taking a more modern take on the weaving effect of the birdnest’s, thin, long timber structures are placed overlapping each other to create the same effect.

STRUCTURE 17
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 and blends in with its natural surroundings.
18
Simple joinery methods are used to connect these structural pieces to each other as well as when attaching it to the selectd tree. Dovetail joint is a key element in the structural system for this treehouse. To avoid relying on nails and timber glue as connecting piece too much, dovetail joint was selected to connect all the wooden planks that was used for the floor, ceilings and walls.

Structure The overall structure of the treehouse is made out of timber.

Timber Columns 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. The colums are kept thin and evenly disperse across the treehouse. They are also used as an asthetic purpose in “recreacting“ the look of tree trunks.

Another main structure that holds up the treehouse are the timber joist that runs across the base/floors of the treehouse. They act as the primary load bearing system for the treehouse before transferring the remaining weight down the columns

Timber Stairs The mode of ascending and decending within the treehouse was kept simple as well. Timber ladders are placed outside of the treehouse as well as 1 within the treehouse as a mean to reach a higher floor level.

Dovetail Joint A construction detail that the treehouse has is each wooden plank that is used as the floor, walls and ceiling are connected through a dovetail joint.

Floorplans
Bedroom 2
The treehouse is divided into two floors with the first floor being a more private space for the users and the second floor serving them as an entertainment space.
First Floor
Bedroom 1
The first floor design is kept to only half the size of the second floor giving it a more enclosed, private space for the users. The area is seperated in the middle with a partition to give a mock room effect; creating two “bedrooms�.

Entrance
Second Floor On the second floor, all other living essentials like bathroom, kitchen and living area is placed here. A balcony facing the hills is also placed there as another form of interaction between users and nature.

COMMUNITY
Community The placement of the treehouses within the community utilizes the topography that’s on site. Maximising both land and water gives the treehouse different views and experience. Be it being on land or the creek, all the treehouses faces the hill and receive either full or partial sunlight.
Circulation 30
The community rely on the trail that’s already available on site as the main form of circulation in and out of the area. All treehouses are connected by a boardwalk which allows the users to freely visit another treehouse with ease.
