BGI Project Study: Host Student Accommodation at Westfield Road

What if 25% of a site has restricted access due to planning requirements? HarrisonStevens’ answer is to make the project a showcase of Blue-Green Infrastructure, Biodiversity Net Gain and Nature Base Solutions. There is no disadvantaged site, only a site with vast and unique opportunities.

Planning approval has been granted for a new Student Accommodation on Westfield Road, Edinburgh. The scheme boast an impressive Sustainable drainage scheme.

Background of the project:

The new design is proposing to demolish the existing office development and erect a new purpose built student accommodation including communal amenity space, external landscaping, car parking, cycle parking and ancillary facilities. Existing residential cottages are also proposed to be converted into an associated energy centre.

The area to the front of the site is within the concession zone and restricted access is legally required. The design team faces many challenges in making the site accessible and user friendly whilst adhering to the restricted access legalities. HarrisonStevens enjoy the challenge being a part of the team that use these constraints to produce a unique space for both nature and the residents.

How does HarrisonStevens examine and propose the site?

The restricted access area provides great opportunity for a sustainable urban drainage solution (SUDs) that filters the water from the roof and hard standing before it enters into the combined sewer. The collection of water will sit within a SUDs basin and the surroundings will be richly planted with native species to increase biodiversity. The wetland-like habitat that will be created in this area will create a 200% increase in new habitats for plants, bees, and small animals. This will create an enjoyable micro-climate, provide delightful visual experience for the residents, and increase biodiversity. The SUDs basin will take over 85% of on-site water run off as well as process 85% of the rainwater on site. A further 5% of rainwater will be processed by soaking through easy-maintenance, heavy duty porous paving. Playful steppingstones will make the restricted access less noticeable and add connection to the water and with nature within the site. The rear garden will also act as an outdoor exercise space for the students.
