PROPERTY RENOVATION · CHESHIRE
JNR Construction delivers full property renovation across Cheshire and south Greater Manchester — whole-house refurbishment, structural reconfiguration and major alterations to substantial period and post-war homes. Load-bearing walls out, services stripped back and renewed, the envelope brought up to standard, and the whole programme run by one named project manager. Occupied or vacant, the sequence is planned before the first wall comes down.
Every JNR home renovation is led by a named senior project manager, accountable for programme, cost, and quality from feasibility through to handover. Not a foreman supervising trades. A construction manager running a project.
Before any work begins, we deliver a detailed pre-construction stage — site survey, scope of works, cost plan, programme, and the appropriate JCT contract. Decisions are made on paper, before they cost anything to change.
On site, we hold the Principal Contractor duties under CDM 2015, run the Construction Phase Plan, control the programme against fixed milestones, and report formally to clients and architects every week. One point of accountability. No surprises.
Removing internal walls to create open-plan spaces requires structural calculations, appropriately specified steelwork, and correctly designed padstones and bearings — all of which JNR engineers in-house alongside the appointed structural engineer.
We manage live-in renovations with a sequenced trade programme that minimises disruption, contains dust and noise to contained zones, and maintains habitable conditions in the areas of the property not under active construction.
Cheshire’s period property stock demands material literacy. We work with lime mortars, traditional lath and plaster, reclaimed brick, and original joinery reproduction — preserving fabric integrity while delivering modern specification throughout.
A full property renovation is not a large refurbishment with more rooms in it. It is a sequence of distinct trades, each dependent on the one before, running through a building you may still be living in. The four stages below are what the term covers on our sites, and the order is not negotiable. Getting it wrong is what turns a nine-month programme into a fourteen-month one.
The first phase is subtraction. Ceilings down, floors up, plaster off where it has to come off, and the building visible for the first time since it was built. This is where survey assumptions get tested: joist ends, wall plates, lintels over openings that were never properly formed, and the condition of the original brick behind the plaster.
Structural alterations follow. Load-bearing wall removal, new openings, steel beams with designed bearings and padstones, and occasionally underpinning where a Victorian footing turns out shallower than anyone hoped. Asbestos is handled under the Control of Asbestos Regulations 2012, which means a refurbishment and demolition survey before work starts rather than a discovery mid-strip.
Everything after this depends on this phase finishing properly. A structural alteration left half-resolved so a plasterer can start is the most expensive shortcut available on a renovation.
With the shell open, the invisible work happens. Full rewire and a new consumer unit, replumbing, heating redesigned around the altered layout, drainage reconfigured where kitchens and bathrooms move, and ventilation designed rather than assumed under Part F.
The envelope is the part most often under-specified. Insulation at floor, wall and roof, continuity of insulation at every junction, and airtightness detailing that actually gets built rather than merely drawn. Where Part L applies to the work, thermal element upgrades come with it, and on a solid-wall period house that forces a decision about whether the fabric can still breathe once it is insulated. Getting that wrong produces interstitial condensation two winters later, long after everyone has gone home.
This is also where late alterations become expensive. Moving a soil stack after the floor is closed is a different job from moving it the week before.
This one question changes the programme, the cost and the sequence more than anything else on the project, and it is worth answering honestly at the start rather than optimistically.
A vacant property is faster and cheaper per square metre. Trades overlap, the strip-out runs in one pass, there is no protection to install and remove, dust and noise stop being constraints, and the programme compresses substantially.
A live-in renovation is a phased project in zones. A kitchen and a bathroom have to stay working throughout, which means temporary provision and two moves rather than one. Hoarding, dust protection, daily clear-down and sequenced trades all carry real cost. Power and water go off by arrangement rather than when it suits the electrician. Most clients who stay tell us afterwards that the phasing was tolerable and the dust was not. We plan the zones before we price, so the figure you are given matches how you actually intend to live.
Finishes are the phase clients imagine and the phase that exposes the quality of everything underneath. Plaster, joinery, decoration, kitchens, bathrooms, floors and the second fix of every service, all of which show up any deviation in the work below them.
Sequencing matters as much here as in the structure. Plaster has to dry before decoration, screeds have to cure before floor finishes, and underfloor heating has to be commissioned and run through a drying cycle before an engineered board goes over it. Compressing those waits is how finished floors fail.
Handover is a document rather than a handshake: Building Regulations completion, electrical and gas certification, commissioning records, warranties, and an as-built record of what sits behind the plaster. On a whole-house renovation that record is worth keeping, because the next person to open a wall will want it.
Where a property is listed or sits in a conservation area the sequence changes again, and consent governs what may be touched at all — that is our heritage renovation work. Where a house is being extended at the same time, the renovation and the extension are one programme rather than two, and should be priced and sequenced as one.
Complex home renovations carry regulatory weight that is often underestimated at the enquiry stage. Three areas apply to almost every project of substance.
Under the Construction (Design and Management) Regulations 2015, domestic clients automatically transfer Principal Contractor duties to the contractor they appoint. JNR assumes those duties formally, maintains the Construction Phase Plan, and compiles the Health and Safety File.
Pre-refurbishment asbestos surveys are a legal requirement on any pre-2000 building before fabric-disturbing works begin. JNR will not start strip-out until a licensed surveyor has completed clearance.
Where alterations affect a boundary or involve excavation near neighbouring property, the Party Wall etc. Act 1996 requires formal notices. We identify them at pre-construction stage, before design is finalised.
A complete transformation of a substantial Hale property — structural reconfiguration of the entire ground floor, removal of multiple load-bearing walls, RSJ installation to achieve the open-plan brief, full replacement of services (heating, electrical, plumbing), bespoke oak staircase and joinery throughout, and high-specification kitchen and bathroom fit-out in all six rooms. The project included complex iceberg-level underpinning works to create an additional lower-ground space. Delivered under a JCT Homeowner Contract. Programme: 52 weeks. Client remained partially in residence throughout the structural phase.
Whole-house renovation depends on what the house is made of, and that varies by town. Solid-brick Victorian and Edwardian villas in Macclesfield and Wilmslow; large mixed-phase houses with mature root protection in Hale; stone cottages needing lime mortar in Bollington; brine instability under Sandbach and Middlewich. The town pages set out the conservation position, ground conditions and planning authority for each – Alderley Edge, Prestbury and Knutsford included.
Building Regulations approval is required whenever structural elements are altered, services are substantially replaced or upgraded, or the thermal performance of the building envelope is changed. In a whole-house renovation, this typically means: a Full Plans application covering the structural alterations, electrical work (Part P, handled by a registered electrician), drainage alterations (Part H), and the insulation specification for any new or exposed elements (Part L). We manage the Building Regulations submission, coordinate inspections, and obtain the Completion Certificate. Some renovation works are exempt — we assess the specific scope and advise before any application is submitted.
The Control of Asbestos Regulations 2012 requires a management survey or refurbishment/demolition survey before any work that disturbs the fabric of buildings constructed before 2000. The duty to manage asbestos-containing materials rests on the building owner. Before any strip-out works begin on a property of appropriate age, JNR requires confirmation that a refurbishment/demolition asbestos survey has been carried out by a licensed surveyor and that any identified materials have been professionally removed or encapsulated. We do not begin structural strip-out works without this documentation.
Yes — live-in refurbishments require a different approach to sequencing, dust containment, and working hours. We design the programme in phases that maintain habitable zones throughout, contain construction work to defined areas, and schedule disruptive works (demolition, structural opening works, concrete cutting) within agreed daily windows. We establish clear site boundaries within the property and manage contractor access to minimise impact on occupied areas. For clients who can vacate during the most disruptive structural phase, we advise on timing that minimises both cost and disruption.
On any renovation involving the removal or alteration of load-bearing walls, changes to the roof structure, underpinning, or installation of structural steelwork, yes — a structural engineer's calculations are required to support the Building Regulations submission and to certify the adequacy of the proposed works. JNR does not design structural elements; we execute them to an approved engineering specification. Where clients do not yet have a structural engineer, we can recommend firms we have worked with successfully on Cheshire renovation projects.
Renovation costs vary considerably depending on the structural complexity of the work, the specification level of the finishes, and the condition of the existing fabric. As a general guide, high-specification whole-house refurbishments in Cheshire typically run between £1,200 and £2,500 per square metre of affected area. The most reliable first step is a feasibility meeting and a detailed scope of works review — published per-metre benchmarks are rarely accurate for a specific property without site investigation and design input. We provide a detailed pre-construction cost plan before any contract is placed.
