Side Return Extensions • Long Eaton, Derbyshire
Long Eaton side return extensions: design, approvals and build
If you own a house in Long Eaton and are weighing up a side return extension, this page sets out how we approach the work locally, what decides the planning route, and what to expect on site. Infilling the narrow strip beside a terraced or semi-detached house to widen the kitchen or living space, usually with a glazed roof to keep daylight in. We handle design, structural engineering, approvals and construction as one contract, so the decisions that carry cost risk are made before you commit to a price rather than discovered once work has started.

Side Return Extensions in Long Eaton: how we approach the work
Our side return extension service in Long Eaton starts with a measured survey of your house rather than a generic quotation. Infilling the narrow strip beside a terraced or semi-detached house to widen the kitchen or living space, usually with a glazed roof to keep daylight in.
The technical crux on most Long Eaton projects is building on or near the boundary, the beam along the length of the removed side wall, rainwater from the neighbouring roof and rooflight detailing. We resolve these on paper first — with a structural engineer where the work needs one — and price the job on what is actually there.
Planning in Long Eaton: Single-storey side extensions are often permitted development if they stay within half the width of the original house and the height limits; corner plots and conservation areas need checking. We check the constraints for your specific address, including any planning history, and tell you plainly which route applies before drawings are commissioned.
Why Long Eaton homeowners use a local design and build team
We are a local design and build contractor, not a national lead-generation site. Long Eaton is roughly 7 miles from Nottingham, which means the same team that surveys your house is the one that designs it, prices it and builds it.
Cost is driven by length of the side return, boundary wall construction, glazing and rooflights, structural beam length and kitchen fit. We do not publish a rate per square metre because it misleads more often than it helps; you receive an itemised, written fixed-price quotation after the survey so you can see what each element costs and what changes it.
We do not invent projects, reviews or statistics to fill a page. What we can promise is a written programme, weekly updates, building control certification handed over at the end, and a twelve-month defects period during which we return to put right anything that fails.
Planning permission in Long Eaton: Erewash Borough Council
The local planning authority for Long Eaton is Erewash Borough Council. Any application for your side return extension — householder planning permission, a lawful development certificate or prior approval — is submitted to Erewash and decided against its adopted local plan and national policy. The council's planning team can be reached by email at Planning@erewash.gov.uk, and applications are made through its own planning pages or the national Planning Portal.
Single-storey side extensions are often permitted development if they stay within half the width of the original house and the height limits; corner plots and conservation areas need checking.
Permitted development: Work that stays inside the size, height, position and materials limits set nationally in the General Permitted Development Order needs no planning application. The limits are tighter on flats, on houses whose rights have been removed by a condition or an Article 4 direction, and on land in a conservation area, National Park or World Heritage Site.
Party walls sit outside the council process entirely. Not a council process at all: the Party Wall etc. Act 1996 is a private notice served on the neighbour when work affects a shared wall, cuts into it, or excavates near their foundations. It runs alongside planning and building control, and being told about it late is what usually delays a start on site.
Before anything is drawn we check your address for the things that change the route: whether permitted development rights have been removed by a condition or an Article 4 direction, whether the property is listed or in a conservation area, any earlier planning decisions on the site, and the position of boundaries and highways.
In practice the order is: constraints check → measured survey → design that fits the route we have identified → submission to Erewash where an application is needed. Where the work is permitted development we recommend applying for a lawful development certificate, because it is the document that proves the position to a future buyer's solicitor.
Building regulations and building control in Long Eaton
Planning and building control are separate approvals. Even where your side return extension in Long Eaton needs no planning application, the building regulations still apply, and the work has to be notified. For Long Eaton that means Erewash Borough Council's own building control team, which also covers Ashfield, Broxtowe and Mansfield, or a registered building control approver of your choice. That team can be contacted on 0115 907 2233 or at buildingcontrol@erewash.gov.uk. We make the submission and manage it for you.
Regularisation: The retrospective route for work already carried out without approval. Openings usually have to be exposed again so the inspector can see what is behind them.
Building on or near the boundary, the beam along the length of the removed side wall, rainwater from the neighbouring roof and rooflight detailing. Those are the elements building control looks at, alongside insulation and airtightness, fire safety and escape, ventilation, drainage, glazing, and the safety of electrical and any gas work.
Inspections happen at set stages rather than all at the end — typically excavation and foundations before concrete, drainage before it is covered, the structural frame or beams once installed, insulation and damp proofing before they are hidden, and a final inspection on completion. We book these and meet the inspector on site so nothing is buried before it is signed off.
At the end you are handed the building control completion certificate, structural calculations, electrical certification, gas paperwork where relevant, and any planning or lawful development documents. Keep them together: this is the pack a buyer's solicitor asks for when you sell.

2. Options and cost range: sketch options with an honest range, before detailed drawings.
3. Approvals: permitted development check, lawful development certificate or planning application as your address requires, plus building control submission.
4. Engineering and fixed price: structural calculations completed, then a written fixed-price quotation with a stage programme.
5. Build: roughly eight to fourteen weeks on site. Yes; the side wall is removed once the new structure is up.
6. Completion: snagging closed out, building control completion certificate issued, defects period begins.

Side Return Extensions in Long Eaton: questions homeowners ask
How long does a side return extension take in Long Eaton?
On site, roughly eight to fourteen weeks on site. Design, engineering and approvals before that usually add several weeks to a few months depending on the route, which is why we start the approvals process early.
How much does a side return extension cost in Long Eaton?
It depends on length of the side return, boundary wall construction, glazing and rooflights and the finish level. We do not quote from a rate per square metre; after a survey of your Long Eaton property you receive an itemised fixed-price quotation.
Can I stay in the house during a side return extension?
Yes; the side wall is removed once the new structure is up.
Do you handle building control for work in Long Eaton?
Yes. We notify building control — Erewash or an approved inspector — provide structural calculations where required, meet the inspector at each stage and hand you the completion certificate at the end.
Which areas near Long Eaton do you cover?
Sawley, Sandiacre and Beeston and the rest of Derbyshire within roughly twenty-five miles of Nottingham. We are based in West Bridgford.
Do I need a party wall agreement for a side return?
Almost always, because the work is on or next to the boundary and the neighbouring wall. Notices are served before work starts.
Will the extension make my neighbour's kitchen dark?
Height at the boundary and roof form are designed to limit that, and planning policy checks it. We show the section drawing so the effect is understood.
Is a party wall agreement needed for a side return extension?
It depends on the work rather than the address. Cutting into or building against a shared wall, or excavating close to a neighbour's foundations, brings the Party Wall etc. Act into play and notices have to be served before work starts. We flag it at design stage in Long Eaton so it never becomes a mid-build delay.
What happens if there is a drain or manhole in the way?
It is common, and it is not a reason to abandon the scheme. Building over or close to a public sewer needs agreement with the water authority, and a manhole can often be relocated or fitted with a sealed double cover. We survey the drainage before pricing your Long Eaton side return extension so the solution is designed in, not improvised.
How do trees and ground conditions affect the foundations?
Clay soils and nearby trees usually mean deeper foundations, and the depth is set by the ground conditions and root influence at your address rather than by a standard detail. Building on or near the boundary, the beam along the length of the removed side wall, rainwater from the neighbouring roof and rooflight detailing. We establish this before the fixed price so the foundation depth is not an open-ended extra.
What insulation and energy standards will apply?
Current building regulations set the standards for insulation, airtightness, glazing, ventilation and heating for the work, and they are checked by building control rather than left to the builder. The specification we quote for a side return extension in Long Eaton is written to meet them, and the detail is in your quotation rather than assumed.
Who prepares the drawings and structural calculations?
We do, as part of the same contract — measured survey, design drawings, planning submission where needed, and structural calculations from a chartered engineer where the work is structural. You are not left coordinating an architect, an engineer and a builder who have never spoken to each other.
How is access and parking handled on a Long Eaton street?
We agree access, skip position, material storage and working hours with you before we start, and let immediate neighbours know. Where the street is narrow or parking is restricted we plan deliveries around it, and any permits required for a skip or scaffold on the highway are arranged in advance.
Do I need planning permission for a side return extension in Long Eaton?
Single-storey side extensions are often permitted development if they stay within half the width of the original house and the height limits; corner plots and conservation areas need checking. We check the planning history and constraints for your specific Long Eaton address before advising, and prepare the application or lawful development certificate where one is needed.
Which council decides a planning application in Long Eaton?
Erewash Borough Council is the local planning authority for Long Eaton. We prepare the drawings and supporting information to the standard Erewash expects and submit the application on your behalf.
