This unique site lies on the south west tip of Hayling Island with water frontage to Langstone Harbour. The brief was to create an outstanding family home with marine views, to maintain good access to the water via the existing slipway and to encourage outdoor living whilst respecting the adjacent designated site. The house replaces an existing single-storey dwelling located at the north of the site. The new house is positioned further from the water on a more sensitive building line established by its neighbours. It will be raised in response to flood risk and a second storey introduced further reflecting the local pattern of built form. The house presents a narrow frontage with the two-storey element set to the east of the plot with a splayed single-storey projection to the west side set further from the road which provides a terrace at first floor and sheltered outdoor space below. The design utilises robust natural materials - dark brick and contrasting white-stained timber - that will weather well in this exposed coastal location. A generously recessed entrance provides a welcoming and sheltered point of arrival and opens into a double-height stair well with full height glazing. On the ground floor there is an integrated garage, three bedrooms with en suites, a plant and boot room with “wet” entrance for outdoor activities and a large family day room with storage and secondary kitchen, views across the harbour and sliding-folding doors onto the garden. On the first floor there is an open plan kitchen-dining-living space with commanding views to the north and west plus a master bedroom suite with views across the eastern Solent to the Isle of Wight. Large glazed sliding doors flank the living space and open onto an external terrace with glass balustrade providing shelter from the prevailing wind. From the terrace a steel and glass spiral stair descends to the garden. A brick chimney serves a wood-burning stove and anchors the building to the site.
