House Extensions in Driffield
House Extensions in Driffield
A market town holds several kinds of house within a mile of each other, and the same brief gets a different answer on each of them. What works on an older property near the centre is rarely what works on a post-war semi at the edge. The survey decides that, not a rule of thumb.
Matching House To Scheme
what your particular house wants.
On an older property near the town centre the useful move is often sideways rather than backwards. Where there is a rear projection with a narrow strip beside it, filling that strip, or carrying a rear extension round into it, widens the house at the point where the plan is meanest and leaves a short garden alone. It also concentrates the drainage questions, because that side strip is usually where the gully and the soil pipe sit.
On interwar and post-war semi-detached and detached houses further out, the plot generally has garden depth and a side gap. That opens up a full width single storey rear extension, an over-garage first floor addition, or a two storey scheme, which gives more floor area per pound because one set of foundations and one roof serves both levels. The judgement there is about restraint rather than possibility, because the easiest scheme to draw is often bigger than the one that reads as subordinate to the house.
Working stock closer to the centre brings older construction into it, with shallower foundations, solid walls and a damp and ventilation arrangement that has to survive being joined to a modern, better sealed structure. None of that is difficult. It just has to be established before a shape is agreed.
- Side infills and wrap-arounds on older property with a rear projection
- Full width single storey rear extensions on established plots
- Two storey, part two storey and over-garage extensions
- Internal reconfiguration so the existing rooms benefit as well
- Structural openings between old and new sized with the engineer
Our Process
how we work.
Site Visit
We measure the house, look at levels, drains and boundaries, and find out how you use the place now.
Assessment
What this particular house and plot will take, rather than what the last one down the road took.
Options
Two or three genuine approaches with outline costs, so the shape is a decision rather than a default.
Route
Permitted development, prior approval or a full application to East Riding of Yorkshire Council.
Approvals
Planning where needed, building regulations always, and party wall notices where a wall or foundation is shared.
Build
Groundworks through to decoration by the practice that drew it, to the figure quoted at the outset.
Driffield
the same brief, four different answers.
Two families can want exactly the same thing from an extension and need entirely different buildings, because the houses they start from are not the same.
Permission
which route the scheme is on.
Driffield applications go to East Riding of Yorkshire Council. Householder permitted development allows a useful amount of work against fixed limits on depth, on overall height and on eaves height where the extension sits near a boundary, and those limits are more generous for detached houses than for attached ones. Side extensions and anything at first floor are treated more tightly, and there is a prior approval route for deeper single storey rear extensions where the neighbours are notified first.
Rights are reduced on designated land, so if the property sits within a conservation area the assessment changes and materials, roof form and street visibility become part of the argument. Rights can also be removed entirely by an Article 4 direction or by a condition on the original permission, which is worth checking on estate housing. Where a scheme is genuinely permitted, a lawful development certificate is a cheap way to have that in writing.
- Permitted development, Article 4 and condition checks for your address
- Prior approval applications for larger single storey rear extensions
- Lawful development certificates and full householder applications
- Design and access statement written for the scheme rather than templated
- Officer and neighbour correspondence handled by the person who drew it

The Technical Side
drains, foundations and party walls.
Three things regularly move a design after it has been drawn, and all three are avoidable. A public sewer or a shared lateral drain under the garden, which normally needs a build over or build near agreement with the water authority and a foundation designed to protect the pipe. Mature trees on shrinkable ground, which can require a substantially deeper foundation, confirmed on site by building control before concrete is poured. And the Party Wall etc. Act 1996, where a wall is shared, a new wall goes up to the boundary line, or a foundation is excavated close to a neighbour's structure.
None of those is complicated on its own. They cause trouble because they are discovered in the wrong order. A drainage survey, a look at the trees and an early view on party wall notices cost very little at the start and remove most of the reasons a build price moves.
- Drainage survey and build over agreement with the water authority
- Foundation depth allowance for mature trees on shrinkable ground
- Party wall notices served with the statutory periods intact
- Building regulations drawings, calculations and inspection stages
- Level thresholds resolved between the existing floor and the new

Questions
house extensions in driffield, answered.
Which council handles extensions in Driffield?
East Riding of Yorkshire Council. Driffield is within the East Riding, so applications are determined under its local plan rather than by Hull City Council. We submit through the Planning Portal and correspond with the case officer directly.
Which type of extension is right for my house?
It depends on the house rather than on the preference. Older property with a rear projection often gains most from filling the side strip or wrapping round it. A semi with garden depth and a side gap usually has more options, including two storey and over-garage. That is what the first visit establishes.
Is my property likely to be in a conservation area?
It depends on the address rather than on the town. A historic centre is the kind of area likely to carry a designation, while later housing further out generally does not. Where it applies, permitted development rights are reduced and the officer will look closely at materials and street visibility.
Is a two storey extension worth the extra planning risk?
It can be, because one set of foundations and one roof covers two floors, so the cost per square metre falls. Against that, the officer will scrutinise bulk, overlooking and whether the extension stays secondary to the original house, and the disruption reaches your bedrooms rather than staying downstairs.
What is a wrap-around extension?
It is a rear extension carried round into the side strip beside a rear projection, so the two parts become one plan. It usually produces a far better ground floor than either half would on its own. The drainage in that side strip is normally the part that needs designing properly.
Do I need planning permission?
Not always. Many single storey rear extensions fall within permitted development, subject to limits on depth, overall height and eaves height near a boundary. Those rights are reduced on designated land, do not apply to flats, and can be removed by an Article 4 direction or by a condition on the property.
How long will the whole thing take?
Approvals are usually the longer part. A householder application is normally determined within eight weeks of validation, and building regulations and party wall notices run alongside. Construction is weeks for a single storey extension and months for two storey or wrap-around work.
Will the extension need deeper foundations?
Possibly, depending on ground conditions and any mature trees close to the new work. On shrinkable ground, seasonal movement and root influence can require a significantly deeper trench. Building control inspects the excavation before concrete is poured, so we allow for it in the quote rather than after.
Do you cover the villages around Driffield?
Yes. Beverley, Walkington, Hornsea, Cottingham and the settlements between them all fall to East Riding of Yorkshire Council, so the framework is the same. We work across that area and into Hull, and the site visit always happens in person.
What happens if a drain runs under where I want to build?
A private branch serving only your house can usually be diverted with the groundworks. A public sewer or a lateral drain shared with neighbours normally requires a build over or build near agreement with the water authority, with the foundation designed to protect the pipe and preserve access to it.
Do you build the extension or hand it to a builder?
We build it. The architect who designs the scheme oversees the construction, 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 figure we stick to.
Can you tell me whether the scheme will be approved before I pay for drawings?
We give an honest feasibility view after the site visit. Where a scheme is unusual, or where something comparable nearby has been refused, a paid pre-application enquiry to East Riding of Yorkshire Council is often worth it for an officer's early opinion in writing.
