Urban Design: Principles and Practice by Rachel Kerr of MSc Planning

Our first student in this year was an unexpected one. For some time now planning tutors have been encouraging their students to branch out into modelmaking as a tool to explain their proposals. Rachel Kerr decided to jump in and, having prepared her initial drawings for the model over the break, had no problem doing so.

Rachel Described the project for us:

The brief was to identify a disused corner site with a total area of less than 1 hectare for which we had to produce a redevelopment proposal. The site I worked on is to the west of Salford Central Station and is currently used for car parking (although it has been identified within the Salford Central Regeneration Strategy). The assignment requested that we assess the characteristics of the site and the surrounding area and use this analysis to produce a detailed brief for proposed redevelopment. Due consideration was given to urban design principles such as frontage, scale and public space. It was my intention to ensure that the site sits comfortably in within the surrounding area, whilst utilising the corner location to create a landmark for passing traffic.

The project uses simple material differences to divide the elements of the site. Because the model was made from laser cut ply there was the unavoidable scorching of the material edge. Rather that removing this, Rachel decided to capitalise on the burnt colour and stained the top surface of her site context buildings to match given them a dark colour in contrast to the sanded and clean look of her site in question.

Due to the small scale (1:500) of the model the site and road details we represented as engrave lines as any more definition was deemed of little importance to the overall representation required.

Once again the locally harvested ‘trees’ from our own model tree plant, as used on other projects, came in very useful and provided a natural and great finishing scale accompaniment along with a small number of 1:500 cars. Grassed or ‘Green’ areas are represented with a mottled green paper that gives a subtle contrast to the birch ply base.

The model was completed over approximately 3 days and is a good example of how to simply but effectively show the context of a site.

How to Save Money and Materials when Making Contour Models

Just before the Christmas break I made a post about the benefits and importance of concious planning and material consideration when thinking about your models. Here is a great example carried out by a group of 3rd year students over the last few days.

This group set out to produce a contour model of a site they have been given to focus on for redevelopment. They took the time to approach us before starting to plan their model which resulted in a huge saving for them in cost and in the materials saved.

Rather than using entire sheets of MDF to build up contour layers We suggested they amend their drawing to construct the contours using the ‘step’ method. This means reducing each contour piece to a fraction of the full sheet size with the only non visible area being a small step to which the piece above can be fixed.

Out of the original materials estimate of 25 full 4mm x 800mm x 450mm sheets for the main contour section of the model the amended drawings helped to decrease this number to just 6.

At the current cost of £2.50 per sheet, the original cost of material for this part of the model would equate to £62.50. After redrawing the file and planning each cut sheet the 6 sheets required cost just £15. A huge saving of £47.50 and 19 full sheets of 4mm Medite MDF.

As you can see it is well worth taking the time to evaluate what it is you are producing and the necessary material required. A good place to start is with your tutors, Jim and myself who are dealing with this subject matter everyday.
