Custom House London, a Grade I Heritage Listed building, boasts a prime location on the River Thames’ north bank with over 150m of direct river frontage. Spanning a 2.4-acre site, it offers expansive views of Tower Bridge and Hayes Galleria, encompassing a gross internal area of 212,000 sqft and a net internal area of 150,000 sqft across four floors and a basement divided into the East Wing, Central Section (Long Room), and West Wing. It provides excellent transport links, being close to key Underground and train stations, combining period and modern features. The current building accommodates around 170 rooms and extensive parking for about 140 vehicles. With a rich history of redevelopment since 1275 figures like Geoffrey Chaucer worked here, and architects like Christopher Wren and Robert Smirke contributed to its design, enduring fires and rebuilds. Recently vacated by HM Revenue & Customs, this historically significant but publicly overlooked building now stands empty.
