The towns burned, and rebuilt on their own plots
Three of the market towns I work in went up in flames. North Walsham lost 118 houses and 70 shops on 25 June 1600. Fakenham burned in 1660, in 1718, and again in 1738. Holt went up in about three hours on 1 May 1708. Each time the town was rebuilt on the plots it already had, so the street pattern is older than nearly every building standing on it.
Fakenham's conservation area appraisal puts the consequence better than I can. Most of the town's older buildings are Georgian, it records, either rebuilt or refronted after the last fire. Then it adds that surveys of some of those buildings have turned up seventeenth-century features which survived at least two of the fires.
That is worth carrying round a house with you. A Georgian front in this part of Norfolk is frequently the rebuild's face, and the thing behind it can be older, built to different rules, and carrying the movement history and the odd floor levels to prove it. I have to get behind the elevation to find out which building I am actually looking at.
Flint is the constant; what changes is the flint
North Norfolk has no natural stone of its own. The district council's design guide says so plainly: with no stone to hand, local builders had to be content with brick and flint, and the district remains predominantly a red brick and flint area today. Read the appraisals town by town and the same three things come back: flint, red brick dressings, red clay pantile over the top.
What changes over a few miles is the flint itself. On the coast at Sheringham and Cromer it is beach cobble, rounded and picked up off the shore. In the Glaven valley behind Blakeney it is knapped, split to show a black face and squared up, and the council reserves that treatment for the higher-status buildings. Blakeney's appraisal explains why any of this is so: stone and gault brick are rare there because they could not be got locally. Before the railways you built from what was under your feet or on the beach at the bottom of the lane, so a wall here is a record of the ground it stands on. Where you do find an imported material, somebody paid to bring it in, and that usually tells you something about the building's status and its date.
On the roofs, reed is the native option where it is sourced locally. Wheat and straw thatch has no real precedent in the district, whatever a previous owner may have put up there.
The ground changes, and the town name won't tell you how
The British Geological Survey maps this district as a patchwork, and at parish scale it isn't uniform in the way you might expect. North Walsham sits on a single free-draining sand and gravel across forty-six of the forty-nine points I sampled on a four-hundred-metre grid, and Holt is nearly as consistent. Cromer, twenty miles up the road, has four deposits under a grid the same size, and no one of them covers half the town. Uniform parishes and mosaics sit side by side, and the name of the town you are buying in tells you nothing about which of the two you are standing on. Your address does.
That matters because most of the older stock sits on shallow foundations, and a shallow foundation follows whatever it was built on:
- Free-draining sand and gravel, the largest single deposit here, stays put. Seasonal shrink-swell largely comes off the table, so cracking has some other cause and it is worth chasing that before anyone reaches for underpinning.
- Clay-bearing till brings the familiar tree, drain, and seasonal movement questions.
- Soft and compressible ground, along the valley bottoms and behind the quays at Wells and Blakeney, brings settlement, which is a different mechanism and wants describing as such.
- Bedrock at surface, chalk or crag, sits under the footings in a small share of the district.
The district council reaches the same conclusion from the other end. Because the geology of North Norfolk is fairly complex, its design guide says, marked variations exist in architectural character across the district, and it carries maps of flint distribution, roofing materials, and wall construction to prove the point. The ground is legible in the walls as well as under the footings.
There are two coasts here, and they are governed differently
The North Norfolk shoreline is covered by two shoreline management plans, and they split at Kelling Hard, near Salthouse.
West of that line, SMP5 runs to Hunstanton across barrier, dune, marsh, and quay. Every unit I checked, including the east bank at Wells and Blakeney itself, is Hold the Line through all three epochs.
East of it, SMP6 runs to Lowestoft Ness along soft, actively eroding cliffs, and the picture is quite different. The defended towns hold: Sheringham and Cromer are Hold the Line throughout. The stretches between them do not. Cromer to Overstrand, Overstrand to Mundesley, and Mundesley to Bacton all reach No Active Intervention in the current epoch, which runs from 2025 to 2055. Two houses a mile apart can sit under opposite policies, and the BGS maps landslide deposits along the cliff strip from Runton round to Mundesley.
If a property here is near the cliff, the shoreline plan and the local authority's coastal position are questions to settle well before the roof is. The Environment Agency is careful to say that its projections do not show the precise future position of the shoreline or give information for individual properties, and that some risk can remain even where defences are present. I'll tell you honestly what an inspection can see, and where you need coastal or geotechnical advice instead of mine.
Away from the cliffs, the sea still sets the terms. Salt-laden wind loads a seaward elevation harder than a sheltered one, and buildings here are unforgiving of the impermeable repairs that were fashionable for fifty years. A breathing wall that somebody sealed will show for it.
The towns
Norwich, Holt, Cromer, and Aylsham have pages of their own:
- Holt: a Georgian town rebuilt after the 1708 fire, with older buildings inside the rebuild.
- Cromer: Victorian and Edwardian seaside stock, and what the sea does to it.
- Aylsham: a Georgian market town on ground that changes street by street.
- Norwich: medieval and Georgian city fabric, and the chalk workings under it.
The rest of my patch:
Sheringham. The town built in brick and beach cobble under pantile until the very end of the nineteenth century, long after most places had moved on, and the terraces along Station Road went up in the 1880s. The railway arrived in 1887 and the resort followed. A cobble cottage in Sheringham can easily turn out to be Victorian, and its age isn't something you can read off the wall.
Wells-next-the-Sea. A working port with maltings, shipyards, and rope walks, holding 3,675 people in 1854 when the average Norfolk market town held about a thousand. Then the creek silted, the railway took the coal trade, and the Customs House was shut by 1880. The town kept the buildings, so a good deal of Wells is seventeenth-century flint with brick dressings, and a good deal more is industrial fabric doing a job it was never built for.
Blakeney. The chief port of the Glaven until the channel silted and the trade went. What survives is flint, from small pebbles neatly coursed to chunky flint mixed with brick rubble, with red brick dressings and pantile over it.
Fakenham. Burned three times, and mostly Georgian because of it, with seventeenth-century work found behind some of those fronts. The conservation area is now a small part of a much larger town, so whether your street sits inside the line is a real question with a real answer.
North Walsham. The town's own conservation area appraisal records that its early houses would have been timber frame, clay lump, or flint cobbles with locally made brick dressings. The 1600 fire left little standing before the seventeenth century apart from the church, and the town rebuilt around the market place on its medieval footprint. The plots and the street lines are older than the buildings on them, which is worth remembering when you are looking at a party wall or wondering why a house is the shape it is.
I also cover Weybourne, Cley, Salthouse, Overstrand, Mundesley, Bacton, Reepham, Melton Constable, and the villages between them. If your town isn't named here, send me the address and I'll tell you whether it is within reasonable travelling time.
Which survey
The older core of any of these towns, the listed stock, anything on an exposed coastal elevation, and anything showing movement wants the depth of a Level 3 (Building Survey). A conventional, sheltered, twentieth-century house in sound condition is often well served by a Level 2 (Homebuyer) survey. Send me the address and I'll tell you which one it needs, including when the cheaper one will do.
