House Extensions in North Ferriby
The most common regret after an extension is not the size of the new room. It is how dark the old ones became. Pull the back wall out several metres and the middle of the plan ends up a long way from any window, which is a problem you design out at the start or live with afterwards.
Light In A Deep Plan
keeping the old rooms worth living in.
A house that was well lit with a four metre deep ground floor is a different building once it is seven or eight metres deep. Daylight from a window falls away quickly with distance, so the far end of a deepened plan gets a fraction of what the front rooms get. Adding glazing across the whole rear wall does not fix it, because that light still has to travel the same distance to reach the middle.
What does work is light from above. Roof lights over the new space, a lantern where the plan is deepest, or a glazed link between the old house and the new part, all put daylight where a vertical window cannot reach. So does being honest about the internal walls: opening the old rear wall properly, rather than leaving a doorway through it, often does more than another square metre of glass.
Orientation decides which of those is right. A rear elevation that faces north needs a different approach from one that gets full afternoon sun, where the risk is overheating rather than gloom. That is a decision to make on site with the survey, not from a plan on a screen.
- Daylight strategy set before the footprint is fixed
- Roof lights, lanterns and glazed links designed into the structure
- Old rear wall opened up properly rather than pierced with a doorway
- Orientation and overheating considered alongside the glazing area
- Internal circulation reworked so the new space is not reached through a bottleneck
Our Process
how we work.
Site Visit
We measure the house, note which way it faces and where the daylight actually comes from through the day.
Plan Depth
We look at how far the plan can grow before the existing rooms suffer, and where the light has to come from instead.
Options
Two or three schemes, each with its own daylight strategy rather than roof lights added at the end.
Route
Permitted development, prior approval or a full application to East Riding of Yorkshire Council.
Approvals
Planning where needed, building regulations always, party wall notices where the Act applies.
Build
The architect who designed the scheme runs the site, to the build figure quoted at the outset.
North Ferriby
the new room is easy. the middle is not.
Daylight falls away fast as a plan gets deeper. Roof lights, a lantern or a glazed link are not decoration, they are what keeps the rooms you already have worth using.
The Options
how far back is far enough.
North Ferriby has a mix of older property, some of it near the village core, and a good deal of interwar and post-war housing on generous plots as you move out. On those larger plots the temptation is to extend further than the plan can carry, because the garden allows it. A shallower extension across the full width often produces a better house than a deep narrow one, and it usually causes less argument with a neighbour about daylight.
Where more space is genuinely needed, a two storey or part two storey scheme is worth comparing on cost, because the foundations and roof serve two floors instead of one. The planning question is larger, with bulk and overlooking assessed carefully by the officer, but on a plot with room at the side it is often the more efficient answer than pushing the ground floor further into the garden.
Whichever route is taken, the internal walls deserve as much attention as the new footprint, since a well lit extension reached through a narrow corridor still leaves you living in the old house.
- Full width single storey rear extensions kept to a workable depth
- Two storey and part two storey options compared on cost and risk
- Side and over-garage extensions where the plot has the gap
- Level thresholds resolved between the existing floor and the new
- Heating and ventilation reassessed for the larger volume
Approvals And Ground
what the council and the trench will ask for.
East Riding of Yorkshire Council determines applications here. Many single storey rear extensions fall within permitted development, subject to limits on depth, overall height and eaves height near a boundary that are more generous for detached houses than for attached ones, with a prior approval route for deeper single storey extensions where neighbours are notified first. Rights are reduced on designated land, so a conservation area check against your address comes before any design work.
Below ground, two things regularly move the design. A public sewer or shared lateral drain under the garden normally needs a build over agreement with the water authority. And mature trees on shrinkable ground can require a substantially deeper foundation, which building control confirms by inspecting the excavation before concrete is poured. Both are cheap to establish early and expensive to discover late.
- Permitted development, conservation area and Article 4 checks
- Prior approval and full householder applications to the council
- Drainage survey and build over agreement with the water authority
- Foundation depth allowance for trees on shrinkable ground
- Building regulations package, calculations and inspections

Questions
house extensions in north ferriby, answered.
Which council handles extensions in North Ferriby?
East Riding of Yorkshire Council. The village lies 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 deal with the case officer directly.
Will a rear extension make my existing rooms dark?
It will if nothing is done about it, because daylight from a window falls away quickly with distance and a deepened plan puts the middle rooms further from any glass. Roof lights, a lantern or a glazed link between old and new are the usual answers, and they have to be designed in from the start.
Will bifold doors across the back give me enough light?
Less than people expect. A large glazed rear wall lights the new space well, but that light still has to travel the same distance to reach the middle of the plan, so it does little for the old rooms. Light from above is what reaches the deep part.
Is a lantern better than roof lights?
It depends on the roof and the room. A lantern gives a strong pool of light and a sense of height over one area, while several roof lights spread it more evenly across a wider space. Both need to be planned with the structure rather than positioned once the beams are in.
How deep can a single storey rear extension be?
Permitted development sets limits on depth, overall height and eaves height, more generous for a detached house than an attached one, with a prior approval route for going deeper where neighbours are notified. The more useful question is how deep the plan can take before the existing rooms suffer.
Does which way my house faces change the design?
Yes, and it is one of the things we look at on the first visit. A north facing rear elevation needs light brought in from above to compensate. A rear elevation with strong afternoon sun has the opposite problem, where unshaded glass and a lantern can make the room uncomfortable in summer.
Do I need planning permission?
Not always. A good proportion of single storey rear extensions fall within permitted development. Those rights are reduced on designated land including conservation areas, do not apply to flats, and can be removed by an Article 4 direction or by a condition on the original permission for the property.
What if a public sewer runs under the garden?
You will normally need a build over or build near agreement with the water authority, and the foundations have to be designed to protect the pipe and preserve access to it. It is a manageable process when a drainage survey has happened early, and a redesign when the pipe appears in an open trench.
Will I need deeper foundations because of a tree?
Possibly. On shrinkable ground a mature tree close to the new work can require a considerably deeper foundation because of seasonal movement and root influence. Building control inspects the excavation before concrete is poured, so it is better allowed for in the quote than discovered on the day.
Do you cover the villages along this stretch?
Yes. Swanland, Brough, Hessle, Kirk Ella and Anlaby all fall to the same authority and we work across them and into Hull. The policy is the same in each, while plot size and house type differ enough to change what makes sense.
Do you build it as well as design it?
Yes. This is an architect-led design and build practice, so the architect who designs the extension oversees the construction. The daylight strategy that was drawn is the one that gets built, which is exactly the detail that tends to get lost when a scheme is handed to somebody else.
How long is the house disrupted for?
Most of the new structure goes up before the existing rear wall is opened, so the period when your house is genuinely open is short. A single storey scheme runs to weeks on site once groundworks begin. We give you the sequence with the quote so you can plan around the noisy stretch.
