Aim To design a biodiverse site which will support and encourage wild life and provide a natural view point for visitors to the site. The square is situated next to Sheffield Railway Station and is therefore, a prime location. Providing an environment which is tranquil and natural for both local people and visitors to the city

Circulation The Skywalk (glass bridge) will not only give access to the site but a spectacular view over the site. At a height of 4m, it is level with the road which runs parallel to the site. As the bridge is level with the road it gives disabled people the opportunity to experience the view. At mid point the bridge has a spiral staircase, giving access to ground level. There are other pathways which allow you to explore the site but at the same time protect the plants and animals which live their. In the water section, wooden bridges have been provided to give people the chance to be over the water. Which runs south.

Features There are three features on site, Land Art inspired by Richard Long, Flood water sump like the ones at Lady Bower and a Spiral Staircase adjoining levels

Green Roof Building The Information Centre and Coffee Shop is positioned by the station as this is the most convienient place for people visiting. The green roof is designed with Agrostis Capillaris, Primula Veris and Galium Verum

Habitat Providing a habitat is a difficult job. The needs of animals and insects are many. Putting native plants into the site makes the job a little easier. With this in mind looking at endangered species and meeting that need became very important. Grass Snakes like to be near water and enjoy dense vegetation as do Water Voles therefore expanding areas of water helped with flooding but in doing so provided a good habitat for Voles and Snake. Traditional meadow planting gives encouragement to Butterflies and Bees both rare in cities, while the wetland supports insects like Water Boatmen and Frog Hoppers

Experiential Walking through the site one will experience many different things. The sound of running water, the rustle of leave and grasses. A range of colour from a variety of greens to bright yellow, purple and white. Smell will punctuate the air from a variety of plants.

Vegetation

The site will attract many types of birds insects and animals. The success of the habitat should mean that you will not see them unless you know where to look and know what you are looking for.
