Le Petit Fort

St Ouen, Jersey

The Site

The site in St. Ouen’s Bay is of exceptional sensitivity and importance, being part of Jersey’s undeveloped Atlantic coastal edge. The St. Ouen’s Bay planning framework designates the bay as ‘a special place’ where the objective is to protect and enhance
the natural environment with a strong presumption against inappropriate development.

Le Petit Fort is an historic building – a 20th century folly designed to mimic a 19th century fort with a ‘guardhouse’ and flanking loop holed walls.

The castellated walls which are beautifully built in irregular granite laid in courses, convey a powerful sense of self-contained security and a kind of defiance of the elements of wind and sea.

MJP were commissioned to obtain planning permission for a four bed house with an annex within the existing fort walls.


The ground floor achieves a sense of containment and refuge from the elements, being contained by the existing granite walls. Large sunlit landscaped courts are created to the south, with smaller hard-surfaced courts to the north.

The first floor under a floating cantilevered roof addresses a broader prospect of sea and sky. The study with its roof terrace becomes a granite lookout tower with flagpole and telescope.

At the seaward end, fort steps lead up from the garden court to ramparts that overlook the sea. Underneath, a small enclosed and protected space creates a cool summertime grotto.


Ground floor: kitchen, family room, utility rooms, dining room, sewing room, gym, store, cloakroom facilities, garages, and main entrance.

First floor: living room, study, four bedrooms.
Annex: bedroom, sitting room, kitchen.
