Extensions in Goldhanger

Extending in Goldhanger

Seven hundred and fifty people at the head of a short creek, on plots that were laid out long before anybody needed to get a digger down the side of a house.

Goldhanger sits on the north shore of the Blackwater at the head of its own creek, north east of Maldon, with the B1026 running through the middle on its way from Heybridge to the Tolleshunts. The 2021 census recorded 751 people in the parish. The name is older than almost anything you can see: Domesday has it as Goldhangra, from the Old English for a marigold slope.

Maldon District Council is the planning authority. That holds for the whole of this stretch of shore, Tollesbury included, but it should not be inferred from the neighbours: district boundaries in this county cut across roads and parishes without warning, and it is settled on the address rather than by association.

A conservation area that has moved

Goldhanger was designated on 1 December 1975, and the boundary drawn that day is not the boundary today.

The record for this village shows the original designation and then later changes to it: land added on more than one occasion, and land taken back out. That is unusual enough to matter. Most village conservation areas are drawn once and left alone, so people reasonably treat “we are in it” or “we are not” as a fixed fact handed down from a neighbour or a solicitor twenty years ago.

Here that assumption is unsafe in both directions. A plot that sat outside the 1975 line may be inside the current one, and a plot that everybody remembers as being in it may have come out. The only useful answer is the council’s current mapping checked against your address, and it costs nothing to ask for it. No Article 4 direction is recorded over the village, and that is worth confirming at the same time.

Where a property is inside the line, it becomes article 2(3) land. Class A stops permitting a side extension or a two storey rear extension, and cladding needs an application. Class B stops permitting an enlargement of the roof, so a rear dormer becomes a planning application. Class C is separate and carries no such exclusion, so a rooflight sitting in the plane of the existing slope remains permitted development, provided it stands no more than 150mm beyond the plane of the original roof measured perpendicular and no higher than the highest part of it. In a village where the loft is often the best available space, that distinction is the whole design decision.

The six weeks nobody budgets for

Inside a conservation area, the trees are protected whether or not anyone has ever made an order over them.

This is the conservation area rule that costs Goldhanger jobs time rather than money. Anyone intending to cut down, top, lop or uproot a tree in a conservation area has to give the council six weeks’ written notice first. The requirement is not limited to trees with a preservation order on them: it catches any tree above 75mm in diameter measured 1.5 metres above the ground, which in garden terms is most things taller than a person.

Those six weeks exist so the council can decide whether to make a preservation order, and it can. Removing a branch overhanging where the extension is going, taking out a conifer to make room for a scaffold, reducing a crown so a roof can be re-tiled: each of those is notifiable, and none of them can be done the week the scaffold arrives. It runs in parallel with everything else if it is started early, and it delays the whole job if it is remembered late. Where a tree carries its own preservation order the position is stricter again, and the interaction between trees and foundations is set out in our guide to tree preservation orders and foundations.

No side access, and what it actually costs

This is the single biggest difference between a Goldhanger price and a price for the same extension on an estate.

The village core was built around a lane, not around a car. Cottages sit close to one another and close to the road, side passages are narrow or absent, and a great many plots have no route from the front of the house to the back except through the middle of it. Everything follows from that.

• Excavation. A mini excavator needs roughly a metre of clear width to reach the back garden. Where that does not exist, the dig is done by hand, and hand digging a foundation trench in clay is measured in days rather than hours. It is the same trench and it is not the same price.
• Spoil and materials. With no side gate, muck comes out through the house or over the top. Barrowing through a hallway means boarded floors, a dust screen, a protected route and a slower cycle. The alternative is a conveyor over a boundary or a telehandler placing material from the road, which costs money but buys back days.
• Steel. A beam for a structural opening is not something you carry through a front door. On a landlocked plot it goes over the roof, and that means a crane or a telehandler with a road closure or a permit, booked for a specific morning.
• Skips. On a narrow frontage there is usually nowhere legal to stand one except the highway, which needs a permit from the county council and a lit and guarded skip. Exchanges get booked rather than called for.

None of that makes the work harder to do properly. It makes it slower, and slow is a cost. A quotation for a Goldhanger cottage that has been priced as though a van could reverse to the back door is not a quotation for your job.

Gravel on one side, clay on the other

The ground along this strip of shore is not the uniform London Clay people expect, and that is worth real money in a foundation trench.

London Clay underlies the district, but the ground between Goldhanger and Heybridge carries river terrace sand and gravel over the top of it, in quantities that were worth digging out commercially. The lakes at Chigborough, a short way west of the village off Chigborough Road, are former gravel pits.

Where a plot sits on that granular capping, the seasonal shrinking and swelling that drives foundation depth across most of Essex is far less of a factor, and depths can be more modest. Surface water behaves differently too: a soakaway that would fail a percolation test in heavy clay can work perfectly well on gravel, which changes how the run off from a new roof is dealt with.

Where a plot is on clay, or on alluvium down towards the creek, none of that applies and the usual rules do. The two conditions exist within the same small parish, sometimes within a few hundred metres, so this is a trial hole question at survey stage rather than a village-wide assumption. Two more things to watch: former workings and old pits get backfilled, and backfill is made ground that will not carry a foundation predictably. Our guide to extension foundations covers how the trench decides the answer.

The creek comes further in than you think

Goldhanger’s tidal flood risk arrives as a narrow finger up the creek rather than as a broad plain.

Because the village sits at the head of a creek rather than along an open shore, the higher flood zones reach inland in a thin tongue following the water, then stop. The practical result is that the flood position can change completely across a couple of hundred metres, and two houses on the same lane can genuinely be in different zones. It is not something to read off a village map.

Where a property is in flood zone 2 or 3, the position is the same as elsewhere in Essex. Householder development is exempt from the sequential test, because the house is already there and there is nowhere else to put it. A proportionate flood risk assessment is required, and what it settles is the finished floor level, whether construction below a stated level needs to be flood resilient, and the escape route. Our guide to flood zones and extensions in Essex explains what goes into it.

What people build here

Modest footprints on tight plots, which pushes a lot of the work upwards.

The stock is a compact core of weatherboarded and colourwashed cottages and Victorian brick pairs, a scatter of larger houses, and twentieth century infill and bungalows around the edges. There is no estate of any size, so there is no repeated floor plan and nothing here prices from a template.

On the older core, a rear extension is usually modest by necessity: gardens are short, boundaries are close, and the 45 degree and 25 degree tests that officers apply to daylight and outlook start to bite quickly on a tight plot. Our guide to the 45 and 25 degree rules explains how those lines get drawn. Where the footprint will not stretch, the roof frequently will, and a loft conversion using rooflights in the plane of the slope avoids both the planning route a dormer would need in the conservation area and the ground conditions entirely.

On the newer houses at the edges of the village the picture is ordinary and considerably easier: side access, a driveway, a cavity wall to tie into, and permitted development often available. Garden rooms and home offices are common on the deeper plots, and outbuilding conversions come up regularly, which start as a structural question about what the existing frame and its footing will carry.

Questions we get asked in Goldhanger

My neighbour says we are not in the conservation area. Is that reliable?

Not on its own. The boundary here has been added to and cut back since it was first drawn in 1975, so a recollection from years ago can be out of date in either direction. The council’s current mapping against your address is the answer.

Can I take the tree down before you start?

Not without six weeks’ notice to the council if you are in the conservation area, and not at all without consent if it carries a preservation order. It is worth raising at the first visit rather than the week before the scaffold.

There is no way round the side of our house. Can it still be done?

Yes, and it is routine. It changes the method rather than the possibility: hand dig or a conveyor, steel lifted over, protected routes through the house. What it must not do is stay out of the price.

Is there a coastal charge for building near the estuary?

No. The Essex Coast RAMS tariff applies to net new dwellings. Extending a house that already exists is outside it.

Getting a price for a Goldhanger extension

We are based at West Bergholt and come down the B1026 often enough that the access constraints in this village are familiar rather than a surprise on the day. The larger settlement at the other end of that road works on entirely different rules, and you can read about it in extensions in Heybridge.

Our team comes out and looks at the ground, the access, the trees, the conservation boundary and the flood position, then says what the job depends on before saying what it costs. Most people who call us already have drawings and permission and want a builder to price the work and build it. That is the ordinary job here, and we are glad to work to somebody else’s plans. Where the drawings do not exist yet, we bring in the technician who draws it and the structural engineer we work with, we handle the planning route with Maldon District Council, we notify Building Control, and we run the job as main contractor.

We carry £2m public liability cover and build to current Building Regulations, through to the completion certificate. The survey and the quotation cost nothing.
