THE SALT HOUSE

The Salt House is a rare example of a contemporary UK sea-side house. Constructed
as a weekend retreat and future home to retire for the owners, Salt House carries
forward the Modernist tradition of the experimental ‘beach house’ as a vehicle to
explore new architectural possibilities- site specific yet containing the potential for
wider application. Extensively published in this country and abroad, The Guardian’s
Architecture critic Jonathan Glancey described The Salt House as “one of the best
new houses in Britain today”. In 2006 the house won the Grand Designs Award for
the Best New Build House of the Year.

Client Brief - A Family story
The client for Salt house is a couple whose parents live in the house next door, and
the client spent all her summers there as a child. It is a new house with a long history!
This project benefited from a quite specific client brief in terms of functionality – 3 beds
/baths + guest suite, 3500sf, no swing doors, a £450K budget - but complete openness
in terms of form and materials. The client was interested in the atrium house typology,
and in particular a strong visual connection from 1st floor to ground floor due to the
special needs of one of the clients two children. The project had the added demand of
fulfilling the requirements of new building in a high-risk flood plain. We embraced these
challenges, aiming to design a house sympathetic to its context - yet responding in
a fully contemporary manner to the opportunities of a family ready for modern
sea-side living.

Oyster Cottages and Wind
The two storey Salt House is located at the end of a terrace of 19thC timber-boarded
oyster fishermen’s houses fronting a communal garden sheltered by a sea wall.
Department of the Environment floodproofing measures required lifting the house above
the level of its neighbours; this higher elevation means the house forms a ‘bookend’
to the terrace, balanced by the inn at the terrace’s opposite end.

The form and geometry of the house re-interprets the local vernacular of hipped roof,
bay windowed cottages. The façade ‘bends’ so that the entire north and south facing
facades effectively become ‘bay windows’, maximising sea views to the north and
passive solar gain from the south. The manipulation of the facades in turn deflects
the geometry of the hipped roof to create an irregular, crystalline form. The three
dimensional facade acts as an instrument for engaging with the communal garden,
the land and seascape, while expressing the dynamic forces of the extreme North
Sea weather.

Framing the south facing entrance courtyard, the traditional single storey ‘outrigger’
typical of the lane entrances to the oyster cottages, naturally became a family room
/guest wing. The house has neither a front nor a back per se. Both facades are highly
glazed, permeable screens allowing cross ventilation and views through the house.
Window and balcony openings travel freely across the facades expressing lightness
and movement. The exterior walls and decks are clad in Ipe, a durable hardwood from
sustainable forests that gives the house a silvery weathered shine. The roof is finished
in synthetic slates, matching neighbouring roofs while enabling precision cutting around
gutters, eaves and rooflights. Maldon Council was surprised and pleased with The Salt
House proposals, exhibiting the project in a local exhibition of exemplary new
architecture in Essex, and inviting the scheme to be submitted for local awards.

Inside, interconnected spaces are ‘wrapped’ by wall and ceiling planes. The ground
floor of the building is conceived as a continuous landscape that steps up from the
entrance courtyard to the south facing timber deck. Huge sliding doors lead to the
slate floored central atrium, ‘folded’ staircase and a sunken living area with a fireplace
wall that extends outside to the deck, garden and beach.

Upstairs, a second living space and study is bathed in light from the central atrium
rooflight, with elevated views of the Blackwater Estuary to the west and St Lawrence
harbour to the east. The space is framed by a series of folded element– the timber
balustrades of the mezzanine fold downward to create the staircase, while the facetted
walls of the 1st floor bedrooms are extensions of the trapezoidal rooflight geometry.

Flood-proof Housing Design
From the very earliest stages, Maldon Council’s planning department was supportive
of the scheme but required a full Flood Risk Assessment which was produced as part
of the Planning submission. The design integrates extensive wet-proofing and dry-
proofing measures, the most important of which was elevating the concrete slab on
mini-piles. Not only do the mini-piles allow below ground water to flow past, reducing
hydrostatic pressure on the foundations, they reduce site spoil to zero and, in the
eventuality of long-term water level changes, the house can be jacked up to a higher
level. Given this context Salt House is a prototype for flood-proof residential construction.

Construction System
The house is based on the structural principle of an elevated slab as the base for a steel
portal frame. This allows two stories of column free interior space, corner windows,
and a huge central rooflight opening, which doubles as a ring beam. Timber framing
between steel elements is sheathed with marine ply to stiffen the entire frame. The
owner describes Salt House as ‘a ship ready for the worst the North Sea can throw
at it!’ A local builder’s craftsmanship, open-minded clients, and an attempt to sensitively
transform a familiar local typology roots Salt House in time, place and family history.
