Grand Union Group, the London-based multiple retailer, will open three new pubs by the end of the year, and plans to grow to 16 in 2011. Adam Marshall, managing director, said the next pub to open would be a Young’s-leased site in Wandsworth on 26 August. This will be the firm’s third site leased from Young’s. Grand Union Wandsworth will have nine Thai treehouses in the beer garden, along with a 35ft circular tree bar. The refurbishment, which is being carried out in under three weeks, will cost between £140,000 and £160,000. The decor is in keeping with the rest of the GU estate, complete with floral wallpaper and vintage furniture. A private snug can be hired for up to 60 people, with a separate bar and audiovisual equipment. The venue will serve its renowned gourmet burgers and handmade pizzas for lunch and dinner. The other two new sites will open in November. One is a 7,000sq ft privately-leased unit, located in London’s Paddington Basin area, next to the Marks & Spencer headquarters. The third site is a Punch-leased pub in Godalming, Surrey, which will have a £150,000 refurbishment before opening.
