History of Gunwharf Quays


The site has enormous history! In the 12th century, Richard I first started construction in the area, developing a dock for Royal Galleys. By the 1500s, it had become the site of Portsmouth’s defenses, and by the late 17th century, its stature had grown further, when Gunwharf was established as a main ordnance yard, storing weapons for the navy and for the army to help fortify Portsmouth. The Ordnance Board was disbanded in 1855, and, as ships and armaments developed, the requirement to offload the armament diminished, and the Gunwharf fell into disuse.

The site was re-established as HMS Vernon when the site was taken over by the Navy in 1923. It continued as a naval base, specialising in mine warfare, until it was decommissioned in 1986. All mine divers were trained here, and the site was integral in D-Day preparations.


After HMS Vernon was no longer needed by the Navy, the Ministry of Defense sold off the redundant land, to release monies for reinvestment in other areas of defense expenditure. Portsmouth City Council were keen that the land was used to build and grow the prosperity of the city. Their goal being to regenerate a derelict City Centre site, to open up the waterfront for public use, to create jobs, to improve the attractiveness of the City and therefore increase visitor numbers, and to attract further inward investment.

The development was not straightforward! Funded by VF (South African company who built a shopping marina concept successfully in Cape Town) and Berkeley Homes, the area was declared a conservation area in 1992, and the site offered huge challenges above and beyond the norm due to it’s location and its previous use.
