The first major shopping centre development in the UK since the onset of the recession is set to be given the go-ahead by Land Securities this week. Britain's biggest listed property developer is expected to announce in a trading update on Wednesday that it has secured enough pre-lettings with retailers to begin construction of Trinity Leeds, a 1m sq ft development in Leeds city centre creating more than 120 new outlets. Shopping centre projects across the country, including Trinity, were mothballed as the financial crisis struck; dragging the pipeline of retail developments to record lows. However, Land Securities, financially bolstered after a rights issue and asset sales last year, is keen to restart the Trinity project because it believes an increasing amount of retail sales will focus on the large regional centres, such as Leeds, which is considered to be under-served. The scheme, likely to cost around £350m to build, will begin later this year and should be completed in 2012. Land Securities declined to comment. As well as Trinity Leeds, the company has a 4.2m sq ft development programme in central London, the biggest in the industry. The company is believed to be in talks with Canary Wharf Group over forming a joint venture to develop the iconic Walkie Talkie tower in the City. The Sunday Telegraph, business, p1
