Double Storey Extensions in Long Eaton: how we approach the work
Our double-storey extension service in Long Eaton starts with a measured survey of your house rather than a generic quotation. A two-storey extension adding living space below and bedrooms or bathrooms above, tied into the existing roof and first floor.
The technical crux on most Long Eaton projects is foundations for the greater load, the junction with the existing roof, first-floor structure and the escape and fire strategy for new bedrooms. 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: Two-storey rear extensions can fall within permitted development only under tight limits; most need a householder planning application, and the design has to respect neighbours' light and privacy. 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 footprint over two floors, roof form and junction, number of bathrooms, glazing and extent of first-floor re-planning. We do not publish a rate per square metre because it misleads more often than it helps; you receive an itemised, written fixed-price quotation after the survey so you can see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 double-storey 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.
Two-storey rear extensions can fall within permitted development only under tight limits; most need a householder planning application, and the design has to respect neighbours' light and privacy.
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 double-storey 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.
Foundations for the greater load, the junction with the existing roof, first-floor structure and the escape and fire strategy for new bedrooms. 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.

The process, step by step
1. Site visit in Long Eaton: we measure, look at the constraints — boundaries, drainage, structure, roof — and talk about what is not working in the house now.
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 sixteen to twenty-six weeks on site. Usually, though the phase where the roof and first floor are opened into the house is the most disruptive and is planned with you.
6. Completion: snagging closed out, building control completion certificate issued, defects period begins.

Double Storey Extensions in Long Eaton: questions homeowners ask
How long does a double-storey extension take in Long Eaton?
On site, roughly sixteen to twenty-six 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 double-storey extension cost in Long Eaton?
It depends on footprint over two floors, roof form and junction, number of bathrooms 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 double-storey extension?
Usually, though the phase where the roof and first floor are opened into the house is the most disruptive and is planned with you.
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.
Will a two-storey extension affect my neighbours' planning position?
The 45-degree light test, overlooking and overshadowing are the usual planning considerations. We design to satisfy them from the first sketch rather than after an objection.
Can the upstairs be a bedroom with an en-suite?
Yes; drainage routes and the fire escape strategy are planned early so the layout works.
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.
How do payments work?
Against a written stage programme tied to completed work — never a large sum up front for work that has not happened. Each stage is set out in the quotation before you sign, so you know what has to be finished before the next payment falls due.
What happens if the survey uncovers something unexpected?
We tell you straight away, in writing, with the options and what each one costs before anything is done. Most surprises in older Derbyshire housing stock — old wiring, unsupported walls, previous unapproved alterations, damp — are found because we look for them at survey stage rather than after the walls are open.
Do you offer any guarantee on the work?
Yes — a twelve-month defects period from completion, during which we come back and put right anything that fails. Alongside it you hold the building control completion certificate and the certification for electrical and gas work, which is what a surveyor or solicitor will look for.
What do I receive when the double-storey extension is finished?
A closed snagging list, the building control completion certificate, any planning or lawful development paperwork, electrical and appliance certificates where relevant, and a twelve-month defects period.
Is a party wall agreement needed for a double-storey 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.
Do I need planning permission for a double-storey extension in Long Eaton?
Two-storey rear extensions can fall within permitted development only under tight limits; most need a householder planning application, and the design has to respect neighbours' light and privacy. 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.
