Opened in July 1912 by the London General Omnibus Company to house their Central London bus fleet operating in competition with the MET trams. Just before World War II the allocation at Palmers Green was entirely AEC Regents, whilst afterwards it was allocated AEC Regent III RT, RTL, RTW and SRTs the only garage to be allocated all four standard double deck types, although none could fit in the garage until the roof could be raised by 10 inches, which was completed in 1952 after a process taking 20 weeks. The garage was further modernised in 1974 by which time 60 buses were allocated. AEC Routemasters arrived in 1969 replacing the RTs, but the RTs lasted there until 1978.
