Architecture Urban Design Interior Design Portfolio 2006-2016
Hello... I’m Stefanie, an architect and urban designer based in London. After graduating from Victoria University of Wellington with a BArch (first class hons.) in 2010 and from The Bartlett School of Architecture (UCL) with an MArch in Urban Design in 2013, over the past six years I gained a broad range of experience in architecture and spatial design. I have worked as part of both small and large practices, as freelancer in a multi-disciplinary team, and I have led numerous jobs as project / sole-charge architect from conception through to completion. Projects I was involved with as key personnel include high-end private residential developments, interior fit-outs, exhibition design, conceptual design, visualisations, large scale residential developments and urban design projects in New Zealand, Germany and the UK. I like simple forms, unambiguous communication, sustainable design and working out the nuts and bolts of a project until everything works perfectly. (Yes, I’m German after all.) This portfolio is divided into two parts ‘Small Scale’ and ‘Large Scale’ to represent the diverse range of my previous experience. Physical copies and complete sets of working drawings / other samples of current work will be sent / shown on request as will details for referees.

LINKED A Transport System as Catalyst for Urban Intensification Algiers City, Algeria 2012-2013
This project is built on a body of research on methodologies of catalytic interventions in a sub-urban setting to aid and direct development. Based on this a strategy to organise a chaotic and partially built up area into a functional, well-connected, and sustainable part of the city was developed. A combination of administrative break down during two wars and constant rural exodus towards the capital has led to a bitter housing shortage and the erratic development of Algiers with vast suburban expansions that all depend on a single urban centre. The combination with an inadequate transport system has led to a very high percentage of private car ownership, which is manifested by an extensive network of highways that further fragment the city. The project builds on the principle of intensification of the sporadically inhabited slopes in close proximity to the existing centre as proposed in the current Algiers Masterplan for 2029 (PSA’29) to create a higher density central city with clearly distinct nature reserves. A proposed 25km light rail track is the starting point for all following steps. Initially it expands the existing modest public transportation system to create a cohesive network in the hillside areas, which are currently occupied by sporadically placed self-built residences lacking basic services and access due to the difficult topography. Peculiar convex and concave conditions along the proposed tram, cycle and pedestrian path are created due to the steep terrain, which serves as starting point for a new spatial ordering principle. New neighbourhoods, formalises existing green areas into a nature reserve, and creates much needed public spaces. A series of courtyard and slab typologies are adapted to the terrain to create variations in density, porosity and views. A typological approach for both the path and building strategy allows this strategy to become a model applicable to other areas and cities with similar needs and conditions.

URBAN MORPHOLOGY STUDY
A study of the development of the existing urban fabric in Algiers forms part of the research for the MArch Urban Design thesis. It was conducted with the aim to reveal effects and connections of political, cultural and economic factors outlined in the initial research on spatial and urban evolution, the public realm and building typology.
LARGE SCALE
Algiers City Historic Context
A simple and consistent style of representation was chosen to allow referencing and comparison of the urban fabric on different scales, block lay-out and size, building typology and streets at significant locations and points in time.

3. NEW PUBLIC SPACES
2. PLOT DIVISION
Twenty-six new public spaces are proposed to be developed along the proposed tram line. Civic functions and public institutions are, along with transport infrastructure, the most neglected element in the existing suburbs.
A series of new medium- and highdensity building plots are created on the occupied side of the path. The existing built environment, curvature of the tram path, and terrain dictate the division of the land.
New public spaces lined by mutated standard building types are placed to as catalysts for the development and sustainability of a local economy.
1. NEW LIGHT RAIL LOOP
EXISTING PUBLIC TRANSPORT The existing public transport network runs along the flat waterfront only. Reliance on the old urban centre near the coast as main urban hub in this city of over 3 Million creates a problematic condition. The hilly suburbs near the centre are, despite their physical proximity, cut off from rather than connected to city centre by the highway system. EXISTING ROAD NETWORK The existing road network is coherent as a high-speed system, but fails on a secondary, slower speed level. Lack of suburban centres and pedestrian friendly streetscapes increase dependency on private car ownership and on the existing single urban centre leading to daily traffic congestion and frustrating commutes. Particularly in the hilly suburbs road access is poor and commutes are drawn-out.
A new light rail transport loop expands the existing public transport network into the topographically challenging western suburbs adjacent to the city centre connecting these currently spontaneously developed areas not only to the urban centre, but also to each other. 4. NEW ROADS AND PATHS New roads and paths are created to complement existing road infrastructure wherever possible to create a coherent pedestrian and vehicle access in the existing and new neighbourhoods. Limited vehicle access within the proposed neighbourhoods encourages walking, cycling and use of the new tram system to access both city and the immediate vicinity. VEGETATION
BUILT ENVIRONMENT Due to the challenging topography and poor access the western suburbs thinly occupied despite their location in close proximity to the highly desired and over-populated urban centre. Some of the ridges are developed with medium-rise government initiated social housing developments and are served by basic roads and services. Slopes are populated sporadically by self-built singlefamily residences close to the ridges, the lower slopes are largely untouched and used as dumping ground for rubbish and sewage.
A rich band of native vegetation inhabits the hillsides surrounding the urban centre of Algiers. Typical self-built concrete and brick in-fill residences are dotted around the often steep terrain generally lacking infrastructure and road access. Poor access and lack of landscaping lead to this potentially valuable reserve to be unused and maintained poorly. TOPOGRAPHY The old Medina and French city, the single urban centre of Algiers and main place of business and employment, are surrounded by topographically challenging terrain.
COASTLINE The existing urban centre is located on the coast making the route through the hills behind it the only and most important connection to the vast suburban areas of Algiers.

This strategy reflects the traditional squares in the Medina that are important gathering places and are surrounded by covered arcades. 02
Concave - Informal Public Space Typical plan at concave area along the transport path. Two to three storey buildings are organised around a crescent shaped plaza that is linked to the park / reserve below.
03
Convex - Promenade Typical convex condition along the main path which is elevated over the nature reserve offering views over the gently sloping landscape. Stairs and pedestrianised streets between medium rise terraced buildings connect the larger streets accessible by vehicles along the contour lines. The radial lay-out of the blocks work with the difficult terrain creating a logical network with good connections to public transport from each point of the proposed development.

Traditional Korean architecture embraces and opens up to the surrounding landscape, helping to create a strong visual and psychological connection to nature. As one of the most fundamental spatial and cultural concepts, this Master Plan strives to create and enhance this condition throughout the urban fabric, architecture, and landscape. The regeneration of Jamsil is a unique opportunity to re-devise this architectural concept on a larger scale with the aim to reconnect the area with the existing and newly established environment. Based on this overarching concept, four design principles address the problems facing the existing site. Infusing Public Access Currently used as a parking lot with poor connectivity to its immediate surroundings, the existing boundaries to the neighbouring districts will be perforated with pedestrian and cycle paths. Six pedestrian bridges across the Tancheon and a ferry connection across the Han encourage integration into the immediate context and invites visitors to enter the site.

Flood Landscape The gradient of the site intentionally moves surface drainage towards water features for public amenity or towards the wetland retention areas to alleviate flooding on site. Using the natural flooding of the Han River and bringing the tidal flow back to the Tancheon River, the natural wetland is reintroduced to the site. The flooding is an integral part of the design: The flexibility of the landscape at the river’s edge is apparent through multiple uses year round regardless of flooding levels.

The site section points out the relationship to both the urban surroundings and the waterfront. The stadia relate to both the city and the nature reserve by opening up the facade two
ways to the bustle of the stadium activities as well as the various public spaces around the large structures. Public areas in a variety of scales enable flexible activities during all seasons and throughout the day and night.

TURANGA WAEWAE A Place to Stand Wellington, NZ 2009
01
Turanga Waewae is one of the most wellknown and powerful Māori concepts. Literally turanga (standing place), waewae (feet), it is often translated as ‘a place to stand’. Turanga Waewae are places where we feel especially empowered and connected. They are our foundation, our place in the world, our home. 02

The role of physical space in the forming, exchanging, and recollecting of memories is the conceptual starting point for this project. Explored through the program of a space dedicated to citizenship ceremonies as part of a cultural exchange centre this proposal focuses on the celebration of New Zealand’s diverse societal make up and the
acknowledgment of the contribution each new member makes to the country’s vibrant culture.
Secondly, through the creation of an evocative spatial sequence addressing past and present in the specific context of New Zealand this project explores how architecture can act as connecting element in a temporal sense through the formation of new and revoking of existing memories.
The aim of this project is therefore bi-fold: Firstly it strives to create a place for thriving positive exchange between New Zealanders with various cultural backgrounds.
