The re-building of the stadium commenced and successive building phases during the 1990s eliminated the original running track. The construction of the East Stand some 20 years earlier had begun the process of eliminating the track. All stands, now roofed and all-seater, are immediately adjacent to the pitch. This structure captures and concentrates the noise of supporters. The pitch, the turnstiles, and the naming rights of the club are now owned by Chelsea Pitch Owners, an organisation set up to prevent the stadium from being purchased by property developers.
