In The Mall Bexleyheath, the firm was able to introduce Wallis to the retail portfolio without having to lease a separate store unit to do so, and was also able to close the existing Evans store and relocate its operations into BHS . Meanwhile, at Lakeside Shopping Centre in Thurrock, Essex, the existing two-floor BHS was replanned to a reformatted single-level store to allow Topshop / Topman to relocate from their prior site ( itself earlier expanded into the neighbouring ex-Etam premises ) to take up what was previously the upper level of BHS . ( The previous Topshop / Topman space was itself used to introduce Forever 21 to the centre ).
