Plans have been given the go-ahead for two developments in the Southeast.

A 110,000 sq ft (10,220 sq m) retail park in Tunbridge Wells called Royal Spa is due to begin development this year, anchored by a 50,000 sq ft (4,645 sq m) Marks & Spencer store.

Developer LXB said it expects Royal Spa to be one of the few retail parks where work will start this year.

M&S will be joined by a relocated Allied Carpets store, with further retail and restaurant space still to be signed. Tenants are due to be trading by Easter 2010.

Meanwhile, London Mayor Boris Johnson has approved plans for a£500m regeneration of Ealing town centre in west London.

As part of the works the Arcadia shopping centre will be redeveloped, along with a number of other buildings in the vicinity. Once the project is complete, the site will include 200,000 sq ft (18,580 sq m) of retail space and 567 residential units. There will also be office and leisure facilities.

The plans have been largely drawn up by HKR Architects and Foster + Partners. Work is expected to begin on site in 2012.
