A self-sufficient marsh house in the Broads National Park
Manor Farm House stands alone on Halvergate Marsh, a 12,000-acre SSSI in the heart of the Broads National Park. The house is around 200 years old, in the parish of Halvergate, and looks directly out across the marshes to Mutton's Mill — a Grade II listed wind pump now restored and turning again as of 2024.
We — Julie and Philip Williams — moved here in October 2005 and have spent twenty years making it work beautifully. The result is a house that offers something genuinely rare: complete independence, in one of the most protected and peaceful landscapes in England.
What that independence looks like
The house is reached by a mile-long lane through working marshland, ending in a private driveway at the gates. The remoteness is the point — and the lane is well-drivable in any ordinary car. More on getting here →
We are off-grid and energy-independent, with solar panels, a wind turbine, and diesel generator backup — all installed, proven, and refined over years of real use. You can read about the system in detail and see the twenty-year financial detail. No grid connection means no power cuts, no standing charges, and no exposure to rising electricity prices. In recent years the renewables have typically carried the house for multi-month stretches each summer. The longest unbroken run on record is 148 days (March–July 2019), with 135 days in 2022 and 116 days in 2025. The current run is 56 days and counting, since 9 March 2026. We were surveyed in May 2026 to update the Energy Performance certificate (EPC) for the premises and we were assessed as Energy Rating B.
Broadband is fast and reliable — we engineered our own solution rather than waiting for fibre to reach us, and it works. The full story is here.
Heating and hot water are provided by an LPG boiler with wet underfloor heating in the extension and radiators in the original house. Combined household energy costs — heating, hot water, cooking, and electricity — run at around £100 a month. Full details →
Foul drainage is handled by a modern Klargester sewage treatment plant installed in 2022 — Building-Control-certified and inexpensive to maintain. Full details →
The practical realities of living somewhere this special have all been solved. What's left is the part that drew us here in the first place.
The setting
From the sitting room window, the marsh stretches uninterrupted to the horizon. Mutton's Mill is in the foreground. The light changes hour by hour, and so does the wildlife.
Over the years we've recorded a wealth of wildlife in the garden itself. Barn owls have bred in our nest box every year since 2016 — eleven consecutive seasons, with twenty-four owlets fledged so far. The first egg of 2026 was laid on 29 April. Kestrels have nested here too — in the kestrel box in the garden some years, and in a hollow in one of the black poplars in others. This year's pair have returned to the garden box. Hares give birth and suckle their leveretts in the garden — we've photographed them doing it — and the young hares stay nearby for weeks. Chinese water deer sleep in the garden. Swallows nest in the porch, weasels are regular visitors, foxes pass through from the marsh, and there's a constant cast of garden birds: goldfinches, robins, woodpeckers, and wrens nesting in the hay barn. One of the pheasants will feed from your hand.
Beyond the garden, the land includes Robin Wood — home to two native black poplars (Populus nigra subsp. betulifolia), one of Britain's rarest native trees. Only around 7,000 mature specimens remain in the UK, of which the Otter Trust's Black Poplar Project estimates just 60–80 are in Norfolk. Herons roost in the canopy. Otters cross the dykes (we have a December 2020 photograph of one heading for the front dyke), and Philip managed to get a phone shot of a water vole in one of the surrounding dykes. The garden has unmown areas left deliberately, not from neglect but to encourage exactly this kind of habitat — and it works. White storks occasionally visit the willows from the nearby Thrigby Hall Wildlife Gardens — a curiosity rather than a wild visitor, but a vivid one.

History on our doorstep
The house appears on Faden's map of 1797, Bryant's of 1826, and the tithe map of 1839. It's mentioned alongside Mutton's Mill in Sheila Hutchinson's The Halvergate Fleet: Past and Present. Two hundred years of marsh history sit under its roof. There are a couple of other maps.
For the longer story of how we came here and built the off-grid system, see Julie's account and Philip's account on the Wise Archive.
