In stage 2 of Studio 223, our study area was Kumeu located in the Rodney District.
As part of our studio projects, we each individually drafted up our own growth strategy for Kumeu and created an urban design concept for Kumeu in 2050 as a group. This design concept combined all the best features from each members project for accommodating future growth and stimulating economic activity in Kumeu. In addition, this final project involved the application of good urban design principles and drawing on the knowledge of what we learned in the previous studio course to create a viable and feasible design for Kumeu.
The following is a detailed study of the urban design we created for Kumeu, that focusses on the urban design principles and rationale for a selected block within the design concept.
Urban Design – Detailed Study
The urban block selected for this detailed study from the Urban Design Concept for Kumeu 2050 is a mid rise, 4-storey, residential apartment block with a site area of 120m2.
At a site area of 120m2 (60m x 60m), this meets the guidelines set by the Regional Growth Forum (2003) for Auckland Housing Choices because the suitable site area for a mid rise apartment block is set at 150m2 or less.
The block has been subdivided into 2 main buildings that contain the apartment units and encloses a communal space in the centre of the block. This subdivision of the block enables the presence of an open space and provides residents with the access of it from the street. Furthermore, it allows for adequate sunlight to get into the apartment units this way.
This urban block was selected because it would be interesting for a detailed study, considering that it is surrounding by a different land use and housing typology on each side. The figure below show the exact location of the selected block in relation to the Urban Design Concept for Kumeu and its surroundings of an open space, 6-storey apartment block and a block of row housing.

Urban Design Principles and RationaleThis block has been subdivided and designed in the manner that residents will have a public front facing the enclosing streets and access to a private back in the form of a shared communal space located in the centre of the block. This communal space is semi-private in the manner that is shared amongst the residents and can only be accessed by them because a locked gate prevents public access to this space. Hence this principle is met by the creation of a ‘perimeter block’ from the subdivision to help achieve this principle of a public front and private back.
The selected block is small at 120m2 (60m x 60m) in size. A small block will provide more options in terms of routes and help achieve greater visual and physical permeability. It increases the awareness of pedestrians and drivers that there are other options available to navigate around the urban area, other than the main route of State Highway 16. This also provides residents with more options to access their apartments and the surroundings of the site because residents are able to walk directly through the block, by crossing through the communal space.
A central green communal space is placed in the centre of block as a foundation for facilitating social interaction between residents of the block and as a place of gathering (Nelessen 1994). This communal space integrates hard and soft areas with soft areas of small shrubs and a grass verge that encircles the tree marking the centre of this space and the hard impervious areas of concrete that surround the soft areas. Aside from the street access to this space, residents have direct access from inside the building by the stairs that lead down to this private area.
Peripheral open space defines the edge of the block by a line of small trees. This enhances the block by creating a sense of entry and exit into the block and makes it more identifiable across the landscapes, as well as adding aesthetic quality to the urban area and the surroundings of the block (Nelessen 1994).

The block is a simple and permeable square shape that encourages walking and provides an option of routes to other places in the urban area. This encourages walkability in the block because it is visually permeable for pedestrians to see in all directions. The corners of the building are ‘softened’ by not having sharp 45o angle edges because it promotes pedestrian safety by enhancing vision around the corner.
