Single-Storey Extensions • Chilwell, Nottinghamshire
Single-Storey Extensions in Chilwell, Nottinghamshire
We carry out single-storey extensions in Chilwell and the surrounding Nottinghamshire area from our base in West Bridgford, roughly 5 miles from Nottingham. A ground-floor extension to the rear or side of the house — typically to create an open kitchen, dining and family space — with its own foundations, walls, roof, structural opening and services. 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.

Single-Storey Extensions in Chilwell: how we approach the work
Our single-storey extension service in Chilwell starts with a measured survey of your house rather than a generic quotation. A ground-floor extension to the rear or side of the house — typically to create an open kitchen, dining and family space — with its own foundations, walls, roof, structural opening and services.
The technical crux on most Chilwell projects is foundation depth for the soil and nearby trees, the beam over the opening into the house, and drainage that often runs under the new footprint. 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 Chilwell: Frequently permitted development for houses when depth, height and boundary limits are met; flats, listed buildings, conservation areas and houses with removed rights need an application. We check the constraints for your specific address, including any planning history, and tell you plainly which route applies before drawings are commissioned.
Why Chilwell homeowners use a local design and build team
We are a local design and build contractor, not a national lead-generation site. Chilwell is roughly 5 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, ground conditions, opening width, flat versus pitched roof and rooflights and extent of internal 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 We do not publish a rate per square metre because it misleads more often than it helps; you receive an itemised, written fixed-price quotation after the survey so you can see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 Chilwell: Broxtowe Borough Council
The local planning authority for Chilwell is Broxtowe Borough Council. Any application for your single-storey extension — householder planning permission, a lawful development certificate or prior approval — is submitted to Broxtowe and decided against its adopted local plan and national policy. The council's planning team can be reached on 0115 917 7777 or by email at pabc@broxtowe.gov.uk, and applications are made through its own planning pages or the national Planning Portal.
Frequently permitted development for houses when depth, height and boundary limits are met; flats, listed buildings, conservation areas and houses with removed rights need an application.
Lawful development certificate: An optional certificate confirming that work is, or was, permitted development. Worth having even when no application is needed, because it is the document a buyer's solicitor asks for years later.
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 Broxtowe 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 Chilwell
Planning and building control are separate approvals. Even where your single-storey extension in Chilwell needs no planning application, the building regulations still apply, and the work has to be notified. For Chilwell that means Erewash Borough Council, which delivers building control on Broxtowe's behalf, or a registered building control approver of your choice. That team can be contacted at buildingcontrol@erewash.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.
Foundation depth for the soil and nearby trees, the beam over the opening into the house, and drainage that often runs under the new footprint. 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 Chilwell: 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 ten to eighteen weeks on site. Yes; the opening into the house is left until the extension is weathertight.
6. Completion: snagging closed out, building control completion certificate issued, defects period begins.

Single-Storey Extensions in Chilwell: questions homeowners ask
Which council decides a planning application in Chilwell?
Broxtowe Borough Council is the local planning authority for Chilwell. We prepare the drawings and supporting information to the standard Broxtowe expects and submit the application on your behalf.
How long does a single-storey extension take in Chilwell?
On site, roughly ten to eighteen 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 single-storey extension cost in Chilwell?
It depends on footprint, ground conditions, opening width and the finish level. We do not quote from a rate per square metre; after a survey of your Chilwell property you receive an itemised fixed-price quotation.
Can I stay in the house during a single-storey extension?
Yes; the opening into the house is left until the extension is weathertight.
Do you handle building control for work in Chilwell?
Yes. We notify building control — Broxtowe 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 Chilwell do you cover?
Beeston, Attenborough and Toton and the rest of Nottinghamshire within roughly twenty-five miles of Nottingham. We are based in West Bridgford.
Flat roof or pitched roof?
Deep extensions often need rooflights or a lantern in a flat roof to get daylight into the middle of the plan; pitched roofs usually suit shallower extensions. We show both where both are viable.
Do I need a party wall agreement?
Likely if you are excavating within three metres of a neighbouring structure below its foundation level or building on the boundary. We identify this at design stage.
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 single-storey extension in Chilwell 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 Chilwell 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 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.
Do I need planning permission for a single-storey extension in Chilwell?
Frequently permitted development for houses when depth, height and boundary limits are met; flats, listed buildings, conservation areas and houses with removed rights need an application. We check the planning history and constraints for your specific Chilwell address before advising, and prepare the application or lawful development certificate where one is needed.
