After the end of the hostilities Portsmouth was left with no ground, as Rat Lane had been taken over by the War Office, and found temporary accommodation at a pitch in Denmead with changing rooms being provided by the Fox and Hounds Public House.
It slowly rebuilt a good reputation and attracted a number of high level players including a future Welsh and an Irish International.
In the mid-1950s the local council mooted a ground share on a 50/50 basis with Portsmouth Football Club at a location behind the Authority Central Depot which had previously been a greyhound track.
In 1965/66 the club moved to its current location at the rugby camp in Hilsea behind what had been its original ground in Rat Lane.
A clubhouse was built by the members after considerable negotiation with the Ministry of Defence who owned the rugby camp at the time opening in 1975.
