operate a petrol station near the retail park's entrance at the Chester Road. Other retailers include: B&M Home Bargins, Smyths Toy Store, TK Maxx, Argos and a furniture store. A separate unit was constructed to the east of the retail park at a later date and is now occupied by Betterlife Mobility (a mobility shop by Lloyd's pharmacy). Smaller retail units are provided in a building next to the Sainsbury's supermarket, with the Post Office as one of the tenants. There is a public square to the rear of the Betterlife Mobility unit with a sculpture in its centre called New Birth. Reed Square is in the centre of the estate and was masterplanned by Gillespies and Associated Architects who later produced more detailed designs for Castle Vale Library and Castle Vale Police Station within the masterplan. The site covers and is generally surrounded by housing with some office and educational premises to the southwest. The site previously accommodated shopping facilities which were underused and so the HAT decided to construct a High Street through the centre of the site to make it a community hub. Parkland The provision of green space for the community was a major priority for the HAT and the demolition of the Centre 8 tower blocks allowed for the creation of a new park. The result was Castle Vale Centre Park on Tangmere Drive. It is a landscaped area with a play area and formal bedding areas. It was completed in 2003 and became the first new public park in the city for a decade. It was designed by Fira and Birmingham City Council's Landscape Practice Group. A lighting scheme was devised by DW Windsor Lighting. In 2006, the park won the Civic Trust's Green Flag Award. Project Wagtail was the brainchild of resident Jez Lilley who received a £15,000 grant from Birmingham City Council in 1988 to help transform an area of wasteland to the south of the estate into a nature reserve. He campaigned to schools and businesses and around 500 people helped plant trees and shrubs in the area. Lilley also established a gardening club and was given an office at The Fort Centre, on Farnborough Road. The office became a drop-in centre for unwanted pets and a bird of prey centre was set up, housing fourteen birds. Lilley also envisaged a footpath to encircle the estate and this idea was presented
