Design & Build in Derby: how we approach the work
Our design and build project service in Derby starts with a measured survey of your house rather than a generic quotation. One contract covering design, engineering, approvals and construction for an extension, renovation, conversion or new home, so a single team is responsible from first sketch to completion certificate.
The technical crux on most Derby projects is making design decisions with buildability and cost in view from the start, so the drawings are ones the same team is prepared to build for the price quoted. 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 Derby: Whatever the project needs — permitted development check, householder application or full planning — is handled within the same contract, alongside building control. We check the constraints for your specific address, including any planning history, and tell you plainly which route applies before drawings are commissioned.
Why Derby homeowners use a local design and build team
We are a local design and build contractor, not a national lead-generation site. Derby is around 15 miles from Nottingham and inside our twenty-five mile working area, which means the same team that surveys your house is the one that designs it, prices it and builds it.
Cost is driven by project type and size, structural scope, specification, approvals route and programme. We do not publish a rate per square metre because it misleads more often than it helps; you receive an itemised, written fixed-price quotation after the survey so you can see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 Derby: Derby City Council
The local planning authority for Derby is Derby City Council. Any application for your design and build project — householder planning permission, a lawful development certificate or prior approval — is submitted to Derby City 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.
Whatever the project needs — permitted development check, householder application or full planning — is handled within the same contract, alongside building control.
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 Derby City 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 Derby
Planning and building control are separate approvals. Even where your design and build project in Derby needs no planning application, the building regulations still apply, and the work has to be notified. For Derby that means Derbyshire Building Control Partnership, the joint service Derby City shares with other Derbyshire councils, or a registered building control approver of your choice. 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.
Making design decisions with buildability and cost in view from the start, so the drawings are ones the same team is prepared to build for the price quoted. 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 Derby: 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: set by the project type — from weeks for a structural re-plan to a year or more for a new home. Depends on the project; we plan it with you before the price is agreed.
6. Completion: snagging closed out, building control completion certificate issued, defects period begins.
Types of design & build we take on in Derby
In Derby and the surrounding area we take on extensions, loft conversions, whole-house renovations, open plan re-plans, garage and outbuilding conversions and new homes. Housing stock varies street by street across Derbyshire, so each project is designed for the actual house rather than adapted from a standard drawing.

Design & Build in Derby: questions homeowners ask
How long does a design and build project take in Derby?
On site, set by the project type — from weeks for a structural re-plan to a year or more for a new home. 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 design and build project cost in Derby?
It depends on project type and size, structural scope, specification and the finish level. We do not quote from a rate per square metre; after a survey of your Derby property you receive an itemised fixed-price quotation.
Can I stay in the house during a design and build project?
Depends on the project; we plan it with you before the price is agreed.
Do you handle building control for work in Derby?
Yes. We notify building control — Derby City 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 Derby do you cover?
Spondon, Borrowash and Chellaston and the rest of Derbyshire within roughly twenty-five miles of Nottingham. We are based in West Bridgford.
What is the advantage of design and build over separate architect and builder?
One point of responsibility. The people drawing the scheme are the people who must build it, so buildability and cost are considered from the start and nothing falls between the two.
Can I bring my own drawings?
Yes. We review them for buildability, engineering and cost before quoting, and tell you if anything needs resolving.
How is access and parking handled on a Derby 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 design and build project 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 design and build project?
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 Derby so it never becomes a mid-build delay.
Do I need planning permission for a design and build project in Derby?
Whatever the project needs — permitted development check, householder application or full planning — is handled within the same contract, alongside building control. We check the planning history and constraints for your specific Derby address before advising, and prepare the application or lawful development certificate where one is needed.
Which council decides a planning application in Derby?
Derby City Council is the local planning authority for Derby. We prepare the drawings and supporting information to the standard Derby City expects and submit the application on your behalf.
