House Extensions in Hedon
House Extensions in Hedon
In a town with a historic core, where an extension sits matters as much as how big it is. Work at the rear that nobody can see from the street is a different application from an addition on a visible flank. That distinction usually decides both the route and the design.
Where It Goes
front, side and rear are three different projects.
Permitted development itself makes the distinction. Rear extensions get the most generous allowance, side extensions are treated more tightly, and anything forward of the principal elevation facing a highway is effectively off the table without an application. On top of that, rights are reduced on designated land, and a historic town centre is exactly the kind of place where a conservation area boundary may run down one side of a street and not the other.
Where the work is at the rear and screened from public view, the assessment concentrates on the neighbours: daylight, overlooking, and whether the bulk is overbearing across a boundary. Those are answerable points with reasonably predictable answers. Where the work is visible, the character of the area comes into it and the officer will look at roof form, materials, window proportion and whether the extension reads as subordinate.
So the sequence matters. Decide where the extension can sit, then decide what size and shape it wants to be. Doing it the other way round is how a scheme ends up being redesigned after a pre-application response rather than before it.
It also affects the drawings themselves. A scheme that will be seen from the street needs elevations that show it in context, with the neighbouring buildings drawn alongside it, because that is the comparison the officer is making in their head anyway.
- Rear extensions kept out of public views where that is the simpler route
- Side extensions set back and held narrower than the original house
- Conservation area and listed building checks against your address
- Article 4 direction checks before a permitted development route is assumed
- Roof form, materials and window proportion designed rather than defaulted
Our Process
how we work.
Site Visit
We measure the property and record what is actually visible from the street and from neighbouring land.
Designation Check
Whether the property is listed, in a conservation area, or covered by a direction that removes rights.
Position
We work out where the extension can go before we work out how big it is.
Route
Permitted development, prior approval or a full application to East Riding of Yorkshire Council.
Approvals
Planning and any listed building consent, building regulations, and party wall notices where the Act applies.
Build
Run by the architect who designed it, to the build figure quoted before work started.
Hedon
what can be seen changes the argument.
The rear of a house is usually assessed on its effect on the neighbours. A visible side or front elevation is assessed on its effect on the street, and that is a much longer conversation.
Older Property
extending a house with shallow foundations.
Older houses bring technical questions before they bring planning ones. Foundations are often shallower than a modern extension requires, so the new work is founded deeper and the junction between the two has to be designed rather than assumed. Solid walls behave differently from cavity walls when an opening is formed, and the existing damp and ventilation arrangement has to survive being connected to a modern, better sealed structure.
Where a property is listed, extending it is a heritage exercise and listed building consent runs alongside planning permission as a separate consent on different grounds. Where it is in a conservation area but not listed, the attention goes to what can be seen. In both cases the earlier the designation is confirmed, the less design work gets wasted.
Services are the quiet part of extending an older house. Heating that was sized for the original rooms rarely covers the new volume, and the electrical arrangement often needs bringing up to standard where the work touches it.
- Foundation design where the existing house is founded shallow
- Structural openings in solid walls sized with the engineer
- Damp, ventilation and thermal strategy for the existing fabric
- Listed building consent prepared alongside planning where required
- Party wall notices where the house is attached or built near the line

The Ground
drains, trees and what the plot allows.
Below ground decides more than most people expect. If a public sewer or a shared lateral drain runs under the garden, a build over or build near agreement with the water authority is normally needed before the foundations go in, and the design has to protect the pipe and preserve access to it. A private branch serving only your house is generally easier and can often be diverted as part of the groundworks.
Mature trees on shrinkable ground can require a substantially deeper foundation, with building control confirming the depth once the trench is open. And the amount of the original garden already covered by the house and any outbuildings limits what permitted development will allow, which is worth measuring rather than estimating on a plot that has gained a garage or a workshop over the years.
All of that is established at the survey rather than during the build, which is the only way a fixed build figure can be given honestly.
- Drainage survey with covers lifted before the footprint is settled
- Build over and build near agreements with the water authority
- Foundation depth allowance for trees on shrinkable ground
- Garden coverage measured including existing outbuildings
- Building regulations package, calculations and inspection stages

Questions
house extensions in hedon, answered.
Which council handles extensions in Hedon?
East Riding of Yorkshire Council. Hedon sits outside the Hull city boundary, so applications are determined under the East Riding local plan rather than by Hull City Council. We submit through the Planning Portal and correspond with the case officer directly.
Is my house likely to be in a conservation area?
It depends on the address rather than on the town. A historic core is the kind of area likely to carry a designation, and a boundary can run down one side of a street and not the other. We check your specific property before recommending a route, because designation reduces permitted development rights.
Can I extend the front of the house?
Rarely without a full application. Permitted development does not generally cover extensions forward of the principal elevation facing a highway, and in a historic setting the street scene is exactly what the officer is protecting. Rear or discreet side work is usually the more realistic route.
Is a rear extension easier to get approved?
Usually, because where it cannot be seen from the street the assessment concentrates on neighbour amenity rather than on the character of the area. Daylight, overlooking and bulk across the boundary are the points to answer, and they are more predictable than a design argument.
My house is listed. What changes?
Listed building consent is required alongside planning permission and is assessed on the effect of the work on the building's significance, which is a different test. Schemes usually go better when the addition is clearly secondary and legible as new work rather than imitating the original.
Are the foundations likely to be deeper on an older house?
Often. Many older properties are founded shallower than current standards require, so the new foundation goes deeper and the junction between old and new needs designing. Nearby mature trees on shrinkable ground can deepen it further, and building control inspects before concrete is poured.
Do I need a party wall agreement?
If you are cutting into a shared wall, building up to the boundary line, or excavating foundations within the distances set out in the Party Wall etc. Act 1996, then notice must be served. On attached property in a historic core it is common. The notice periods run into weeks, so it starts early.
What is a lawful development certificate?
It is written confirmation from the council that the work is permitted development and does not require planning permission. It is optional, cheaper than a full application, and decided on fact rather than opinion. In a town where designation varies street by street it is a useful thing to hold.
Do you cover the area east of Hull?
Yes. Hedon, Withernsea and the villages along that stretch all fall to East Riding of Yorkshire Council, and we work across them as well as into the city. The framework is the same in each, while the housing stock and the exposure vary considerably.
Will the extension need to match the existing materials?
Where an application is needed, materials are a planning consideration. On older property an exact brick match is rarely achievable, so the aim is usually a sympathetic match on visible elevations and more freedom at the rear. In a conservation area the officer will look at this closely.
Do you build what you design?
Yes. The architect who designs your extension oversees the site work, which is what an architect-led design and build practice means. The drawn detail is the built detail, and the build cost quoted before you commit is the one we stick to.
How long will the approvals take?
A householder application is normally determined within eight weeks of validation, and listed building consent runs alongside where it applies. Validation is where time is most often lost, so the submission goes in complete rather than being returned for missing information.
