Double Storey Extensions • Calverton, Nottinghamshire
Double-storey extensions in Calverton — from survey to completion
We carry out double-storey extensions in Calverton and the surrounding Nottinghamshire area from our base in West Bridgford, roughly 7 miles from Nottingham. A two-storey extension adding living space below and bedrooms or bathrooms above, tied into the existing roof and first floor. 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.

Double Storey Extensions in Calverton: how we approach the work
Our double-storey extension service in Calverton 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 Calverton 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 Calverton: 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 Calverton homeowners use a local design and build team
We are a local design and build contractor, not a national lead-generation site. Calverton 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 We do not publish a rate per square metre because it misleads more often than it helps; you receive an itemised, written fixed-price quotation after the survey so you can see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 Calverton: Gedling Borough Council
The local planning authority for Calverton is Gedling Borough Council. Any application for your double-storey extension — householder planning permission, a lawful development certificate or prior approval — is submitted to Gedling and decided against its adopted local plan and national policy. Applications are made through the council's own planning pages or the national Planning Portal, where the current householder fee is published.
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.
Prior approval (larger home extension): A deeper single-storey rear extension can be built under the neighbour consultation scheme: the council notifies the adjoining owners, and if any of them object the council decides whether the impact is acceptable. It has to be notified before work starts, not afterwards.
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 Gedling 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 Calverton
Planning and building control are separate approvals. Even where your double-storey extension in Calverton needs no planning application, the building regulations still apply, and the work has to be notified. For Calverton that means Gedling Borough Council's building control team, with the service moving to the Erewash-hosted building consultancy from 1 June 2026, or a registered building control approver of your choice. That team can be contacted on 0115 901 3740 or at buildingcontrol@gedling.gov.uk. We make the submission and manage it for you.
Building notice: A shorter route for straightforward work: the job is notified and then inspected as it proceeds, with no prior plan check. Faster to start, but the risk of a change being required mid-build sits with the owner.
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 Calverton: 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 Calverton: questions homeowners ask
Which council decides a planning application in Calverton?
Gedling Borough Council is the local planning authority for Calverton. We prepare the drawings and supporting information to the standard Gedling expects and submit the application on your behalf.
How long does a double-storey extension take in Calverton?
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 Calverton?
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 Calverton 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 Calverton?
Yes. We notify building control — Gedling 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 Calverton do you cover?
Arnold, Woodborough and Ravenshead and the rest of Nottinghamshire 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 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 Nottinghamshire 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 Calverton 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 Calverton double-storey extension so the solution is designed in, not improvised.
Do I need planning permission for a double-storey extension in Calverton?
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 Calverton address before advising, and prepare the application or lawful development certificate where one is needed.
