House Extensions in Anlaby
House Extensions in Anlaby
The size of an extension is decided by the plot long before it is decided by the budget. Garden depth, the gap to the boundary, where the drains run and how much of the original garden is already built on all set the envelope. We work that out on the first visit, then design inside it.
What The Plot Takes
depth, gaps and how much garden is left.
Four measurements do most of the work. How far the rear wall can come out before the garden stops being usable. How wide the gap to the boundary is, which decides whether a side or over-garage extension is realistic. How much of the original garden area is already covered by the house, the garage and any outbuildings, because permitted development caps that proportion and sheds count. And the level difference across the plot, which decides the floor build-up and whether you end up with an unwanted step.
The interwar and post-war semi-detached and detached housing common in Anlaby generally comes with a decent garden and a side gap, which is why full width rear extensions and over-garage additions are so common on this stock. The generous plot is a real advantage, but it also means the scheme that fits easily on paper is often bigger than the one that reads as subordinate to the original house, which is what an officer will be looking for if an application is needed.
We would rather show you the envelope at the start and design a good scheme inside it than draw the one you asked for and spend three months finding out it does not fit.
- Measured survey of the house, plot, levels and boundaries
- Garden coverage calculated including existing outbuildings
- Single storey rear and full width rear extensions
- Side and over-garage extensions where the gap allows
- Two storey extensions assessed for bulk and overlooking
Our Process
how we work.
Site Visit
Measured survey of the house, the garden depth, the boundary gaps and the levels across the plot.
Constraints
Drains, trees, boundary lines and existing outbuildings recorded, because each one shrinks the envelope.
Envelope
We set out what the plot will take under permitted development and what would need an application.
Design
Two or three schemes inside that envelope, so the decision is about how you live rather than about what is allowed.
Approvals
Submission to East Riding of Yorkshire Council where required, building regulations in every case.
Build
Built by the practice that designed it, to the figure quoted before you signed anything.
Anlaby
the plot decides more than the budget does.
Every site has an envelope inside which a scheme is straightforward and outside which it becomes an argument. Finding that line early is the most useful hour of the whole project.
Below Ground
drains, trees and foundation depth.
The two things most likely to move a foundation are a drain and a tree. If a public sewer or a lateral drain shared with a neighbour runs under the garden, a build over or build near agreement with the water authority is normally needed and the foundation has to be designed to protect the pipe. A private branch serving only your house is usually simpler and can often be diverted with the groundworks.
Mature trees matter where the ground is shrinkable. Seasonal movement and root influence can require a considerably deeper foundation than a straightforward site, and building control will inspect the excavation before concrete is poured, which means the depth is confirmed on site. We allow for that in the design and in the quote, because a foundation that turns out deeper than the price assumed is the classic way an extension budget slips.
- Drainage survey with covers lifted before the footprint is fixed
- Build over and build near agreements with the water authority
- Foundation depth allowance for trees on shrinkable ground
- Surface water strategy for the additional roof area
- Party wall notices where a foundation crosses or nears the boundary line
Permission
when an application is actually needed.
Anlaby applications go to East Riding of Yorkshire Council. A large amount of extension work falls within householder permitted development, which sets limits on depth, on overall height and on eaves height where the extension comes near a boundary, with more room for a detached house than for an attached one. There is a separate prior approval route for a deeper single storey rear extension, under which your neighbours are notified before it can proceed.
Where a full application is needed, the council will consider daylight and overlooking to neighbours, the effect on the street where the work is visible, parking where bedrooms are added, and whether the extension stays secondary to the original house. Those points are answered by the drawings and by a design and access statement written for your scheme. We also check for an Article 4 direction or a condition on the original permission that might have removed rights, which is worth doing on estate housing.
- Permitted development assessment for your specific address
- Prior approval applications for larger single storey rear extensions
- Lawful development certificates where the scheme is permitted
- Full householder applications with a statement written for the scheme
- Building regulations package and inspection stages

Questions
house extensions in anlaby, answered.
Which council handles extensions in Anlaby?
East Riding of Yorkshire Council. Anlaby sits just outside the Hull city boundary, so applications go to the East Riding rather than to Hull City Council, and are judged against the East Riding local plan. We submit through the Planning Portal and correspond with the case officer.
How big an extension can I build without planning permission?
Permitted development works to limits on depth, overall height and eaves height near a boundary, and those limits are more generous for detached houses than for attached ones. There is also a cap on the proportion of the original garden that can be built on. The right answer depends on your house type and plot.
Do sheds and the garage count against what I am allowed?
Existing outbuildings count towards the proportion of the original garden area covered by buildings, so a large shed or a detached garage reduces what is left for an extension under permitted development. It surprises people on plots that otherwise look generous, which is why we measure it rather than estimate.
What is prior approval?
It is a route that allows a deeper single storey rear extension than standard permitted development, on the condition that the council notifies your adjoining neighbours first. If nobody objects within the period, the work can proceed. If they do, the council decides whether the effect on their amenity is acceptable.
Will a full width rear extension get approved?
Frequently, on this kind of plot. The points that decide it are how far it projects, how it affects the neighbour's daylight, and the eaves height where it runs close to the boundary. A pitched or partly pitched roof falling away from the boundary is usually easier than a full height flat roofed box.
How do I know if a sewer runs under my garden?
Lifting the covers is the fastest indication, because the number of connections and the direction of flow usually reveal whether the drain serves more than your house, and a records enquiry with the water authority confirms it. Both are done before the extension footprint is settled.
Do I need a party wall agreement for a rear extension?
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 yes. On a semi-detached house it is common. The notice periods run into weeks, so it is started at design stage.
Could a condition have removed my permitted development rights?
Yes, particularly on estate housing where the original permission for the estate carried a condition removing some householder rights. An Article 4 direction can do the same across a defined area. We check the planning history for the address rather than assume the standard rights apply.
Should I go two storey instead?
It is worth putting the two options side by side. A two storey extension gives more floor area for each pound spent on foundations and roof, but the planning assessment is harder and the disruption reaches the bedrooms. On a plot with garden depth to spare, a single storey scheme is often the easier project.
Do you cover the surrounding villages?
Yes. Willerby, Kirk Ella, Hessle, North Ferriby and Cottingham are all within the same authority and we work across them and into Hull. The policy framework is the same, while plot sizes and house types differ enough to change what is sensible.
Do you build what you design?
Yes. The architect who designs the extension oversees the build, which is the reason the practice is set up this way. The drawn detail is the built detail, and the build cost quoted before you commit is the one we stick to.
What does the first visit involve?
A measured survey of the house and the plot, a look at levels, drains and boundaries, and a conversation about how you actually use the place now. You get an honest view on what the plot will take and which route the scheme is on. It costs you nothing.
