BUILDERS IN STOCKPORT · SK1 TO SK8
JNR Construction is a Cheshire-based Master Builder and design-to-build partner for Stockport’s substantial homes and commercial buildings. For homeowners, and architects who need a contractor they can refer without risk — major extensions, whole-house renovation, new builds, and refurbishment under CDM 2015.
20 Years. 400+ Projects. Federation of Master Builders.
Stockport is a Greater Manchester borough immediately north of Cheshire East, run by Stockport Metropolitan Borough Council rather than a Cheshire authority. Its building stock is unusually varied — Victorian and Edwardian terraces around the town centre and Edgeley, period villas in the Heatons, inter-war semis in Hazel Grove and Offerton, larger homes in Bramhall, and former mills in Reddish. It is also a borough shaped by 37 conservation areas, Article 4 Directions, 464 locally listed buildings, the Mersey, Goyt, and Tame valleys, and an evolving Local Plan.
None of that stands in the way of exceptional building work in Stockport. It does mean every project has to be read against its own neighbourhood. A heritage-sensitive extension in Heaton Moor, the structural reconfiguration of an Edwardian semi in Davenport, a whole-house remodel on a mature Bramhall plot — each one turns on conservation controls, Article 4 status, party walls, drainage, sloping ground, and access on busy streets. In a borough this varied, generic assumptions are what cause redesigns, delays, and cost overruns.
JNR Construction engages before drawings are finalised. We establish what Stockport Council’s planning position, Building Control, and your ground conditions allow on the site — then we build it as Principal Contractor under CDM 2015, with a dedicated project manager, a Construction Phase Plan, careful neighbour communication, and one point of accountability through to Completion Certificate.
Rear, side, and wraparound extensions on Stockport’s Victorian, Edwardian, and inter-war homes — structural steelwork, foundations designed around clay, made ground, and trees, drainage and build-over checks, and Parts A and L.
Whole-house renovation of Stockport period and family homes before you move in. Structural wall and chimney-breast removal, asbestos surveys, damp and ventilation upgrades, and a high-specification fit-out under one project manager.
Architect-designed one-off homes and replacement dwellings on larger mature plots in Bramhall, Woodford, and the Cheshire edge. JNR acts as Principal Contractor under CDM 2015 — groundworks through to Completion Certificate.
Hip-to-gable and rear-dormer loft conversions on Stockport semis and period terraces — structural steel for new floor loads, Part B third-storey escape, Part K staircases, and conservation-sensitive dormer design.
Refurbishment of older commercial, mixed-use, and former mill premises from Stockport town centre to Reddish — Part B Volume 2 fire strategy, Part M access, compartmentation, and Full Plans approval before work starts.
Conservation area and locally listed building work across Stockport’s 37 conservation areas — lime mortar where fabric needs it, slate roofs, chimney stacks, timber windows, and details agreed with the Conservation Officer.
Stockport has 37 conservation areas, including Heaton Moor, Cale Green, Cheadle Village, and Bramhall Park. Each one shapes the build.
Stockport sits within Stockport Metropolitan Borough, in Greater Manchester — not Cheshire East. Stockport Council determines planning applications, Listed Building Consent, conservation area controls, and Article 4 Directions, and Stockport Council Building Control covers the borough, from the town centre to Bramhall, Hazel Grove, and Marple, unless a Registered Building Control Approver is appointed. For substantial extensions, loft conversions, structural alterations, and commercial refurbishment, Full Plans is the safer route.
Stockport’s planning position is evolving. The borough’s last adopted Local Plan dates from 2011, and in September 2025 the government issued a Local Plan intervention letter directing the council to progress an updated plan. Until that work concludes, every Stockport project is checked against the council’s current Local Plan documents, policies map, and live planning guidance before a design or construction route is assumed.
Stockport Council identifies 37 conservation areas in the borough — among them Stockport Town Centre, St Thomas’s, Alexandra Park, Cale Green, Heaton Moor, Cheadle Village, Brooklyn Crescent, Bramhall Park, Bramhall Lane South, Chadkirk, and Brookbottom. Designations vary street by street, so the current conservation area database is checked for every address. Inside a conservation area, windows, rooflines, brickwork, stone detailing, and boundaries all carry weight.
Some Stockport conservation areas are also covered by Article 4 Directions. Where one applies, planning permission may be needed for replacement windows and doors, roof and chimney alterations, boundary walls, gates, and railings, and external changes to elevations fronting a highway, waterway, or public open space — including replacing timber windows with uPVC. Permitted development is never assumed in a Stockport conservation area.
Alongside nationally listed buildings, Stockport Council records 464 locally listed buildings of local architectural or historic interest. Listed Building Consent applies to works affecting a listed building’s special interest, internal as well as external. Locally listed buildings are not subject to consent in the same way, but their heritage value is a material planning consideration — which is why a Stockport renovation needs a heritage check before anyone starts opening up walls.
Stockport’s older streets bring their own constraints. Terraces and semis in Edgeley, Cale Green, and the Heatons often mean Party Wall etc. Act notices, small rear yards, existing outriggers, and shared drains. Sloping streets, restricted parking, rear-access limits, and busy district centres shape deliveries, skips, and scaffolding, so the Construction Phase Plan, welfare, and neighbour communication are set up before work starts.
The borough is shaped by the River Mersey, River Goyt, and River Tame. Flood risk matters most near river corridors, valley-bottom sites, and lower-lying land, and it is checked site by site against the Environment Agency flood map and Stockport Council policy. Older combined drainage, paved urban sites, and sloping terrain can all increase surface-water runoff, and United Utilities build-over requirements are checked before excavation begins.
Ground conditions are rarely uniform. British Geological Survey records for the Stockport area describe boulder clay and outwash deposits of sand, gravel, and bedded clay over low land and filling older valleys, and former industrial land adds made ground and possible contamination. Tree influence, level changes, and steep valley sides all affect foundation strategy, and pre-2000 buildings need asbestos surveys before intrusive work.
We do not make assumptions about any of this. Every JNR feasibility in Stockport includes a site-specific check of the conservation area database, Article 4 records, listed and locally listed status, current Local Plan policy, flood-risk mapping, public sewer records, party wall obligations, and the Building Control route.
Four stages. One dedicated project manager. No gaps between design and build on any Stockport project.
We engage before drawings are finalised. Julian Rowlands reviews the project brief, the site constraints, and the structural intent — identifying the risks that appear in construction but originate in design. We provide a realistic cost assessment based on the scope, not a low number designed to win the job. If the project is not viable within your budget, we say so at this stage rather than halfway through a build.
Every project starts with a site visit and a structured pre-construction conversation covering: the structural approach (what steelwork, what groundworks, what temporary works are likely to be required), the regulatory framework (which Approved Documents apply, whether CDM 2015 notifications are required, whether Listed Building Consent or Conservation Area approval is needed), and the programme implications (realistic timescales for both the pre-construction phase and the build itself).
This engagement costs nothing and commits you to nothing. It does give JNR enough information to provide an accurate preliminary cost plan — not a ballpark figure, but a structured document showing where the costs are concentrated and why.
Where an architect is already appointed, we engage directly with their drawing package at this stage, providing a buildability review and raising any technical queries before the design is finalised. This is the most cost-effective point at which to resolve structural ambiguities.
We do not begin construction until every pre-commencement obligation is satisfied. This is not caution for its own sake — it is the only way to protect the programme once the build starts.
Pre-construction work on a typical JNR project covers:
Building Regulations. Full Plans application submitted to the Local Authority Building Control or an Approved Inspector. Structural calculations produced by the appointed structural engineer and incorporated into the submission. We coordinate between the structural engineer, the architect, and the Building Control Officer to resolve any queries before an approval is issued — not after work has started.
Party Wall. Where the proposed works affect a boundary wall or involve excavation near an adjoining owner's property, Party Wall Notices are served under the Party Wall etc. Act 1996. We assess which notices are required, prepare the notice documentation, and appoint a surveyor where the adjoining owner requires one. We do not begin works within the Act's scope without the notices being formally in place.
CDM 2015 Construction Phase Plan. On projects where CDM 2015 applies, the Construction Phase Plan is prepared and in place before the construction phase begins. This is a statutory requirement under Regulation 12(1) of CDM 2015, not a discretionary document.
Planning condition discharge. Pre-commencement planning conditions are formally discharged with the Local Planning Authority before groundworks begin. Conditions typically cover materials, drainage, ecology, and construction management — each requiring a formal submission and written approval.
Asbestos. On properties constructed before 2000, we require confirmation of a refurbishment/demolition asbestos survey before any strip-out works commence, per the Control of Asbestos Regulations 2012.
JNR Construction is formally appointed as Principal Contractor under Regulation 5 of CDM 2015 on all qualifying projects. This is not a marketing claim — it is a legal dutyholder appointment, made in writing, before the construction phase begins.
As Principal Contractor, JNR's responsibilities include:
Site management. The site is run to a Construction Phase Plan that sets out the site rules, induction requirements, emergency procedures, and method statements for high-risk activities. Every trade operative on site is inducted. Unauthorised access is prevented. Facilities meeting Schedule 2 of CDM 2015 are in place from day one.
Trade coordination. JNR coordinates all subcontractors and specialist trades — structural steelwork, groundworks, M&E, plastering, joinery, glazing, roofing — to a sequenced programme. Trades are appointed against the specification, not substituted for cheaper alternatives without the client's knowledge.
Variation control. All changes to the agreed scope of works are formally issued in writing by the client or their contract administrator, priced by JNR, agreed in writing, and incorporated into the contract sum before the works proceed. Verbal instruction does not constitute a valid variation.
Progress reporting. Clients receive structured progress updates — what has been completed, what is on programme, what (if anything) is at risk — at agreed intervals throughout the build. You are not left waiting to visit site to find out what is happening.
Quality inspections. Staged quality checks are carried out at key milestones: prior to closing in any structural element, prior to first fix boarding, and prior to second fix. Building Control inspections are co-ordinated and attended by JNR's site manager.
Practical completion is not the end of JNR's accountability — it is the beginning of the documented record of everything that was built and how it was built.
At practical completion, the handover package includes:
Building Regulations Completion Certificate. Issued by the Local Authority Building Control or Approved Inspector confirming that the works have been inspected and comply with the relevant Parts of the Building Regulations.
CDM Health and Safety File. Required under Regulation 12(5) of CDM 2015 on all qualifying projects. The file documents the as-built structure, the materials used, the services installed, and any information that will be needed for future maintenance or alteration. It is handed to the client at completion and must be passed on with the property on any future sale.
Gas Safe and Part P certification. All gas work certified by a Gas Safe registered engineer. All electrical work certified by a Part P registered operative, with the appropriate Building Regulations notification.
O&M manuals. Operating and maintenance documentation for installed systems — heating, ventilation, mechanical plant — so the client understands how the building works and what routine maintenance is required.
Snagging record. A formal snagging list produced at practical completion, agreed with the client, and resolved within the defects liability period specified in the contract.
The defects liability period (typically 12 months under a JCT Homeowner Contract) runs from practical completion. If defects attributable to JNR's works appear during that period, we return and resolve them. The client has a direct contractual remedy — not a series of phone calls to a company that has moved on.
Front and Rear Extension & Remodel, Stockport
This total property transformation required more than standard building practices; it demanded complex structural engineering. We installed heavy structural steelwork to alter the load paths, safely supporting wide-span rear glazing to create a modern open-plan footprint. On the exterior, we executed the architect’s vision of a striking contemporary contrast, expertly integrating the new high-specification brick additions against the original white-painted property. The result is a bold, fully Part L energy-compliant home that perfectly bridges the existing structure with modern architectural design.
“I own one of Cheshire’s most prestigious estate agencies and am frequently asked to recommend reliable building companies. I have used JNR Construction for both domestic and commercial work and have first-hand experience of their workmanship and professionalism. The interior oak work has been expertly crafted. I feel fully justified in putting forward JNR Construction.”
Not always, but it should never be assumed. Some Stockport rear extensions, side extensions, and loft conversions can be delivered under permitted development, but that depends on the property type, previous extensions, conservation area status, Article 4 Directions, listed or locally listed status, and planning conditions on newer estates. Neighbour amenity, overlooking, and roof design are common issues on semi-detached and terraced streets. We check the exact property against Stockport Council's conservation area database, Article 4 records, and planning history before any route is recommended.
No. Stockport is in Greater Manchester and is administered by Stockport Metropolitan Borough Council, so Cheshire East planning policy does not apply to Stockport borough projects. Stockport Council determines planning applications and Listed Building Consent, and Stockport Council Building Control covers the borough unless a Registered Building Control Approver is appointed. Some SK postcodes, such as Poynton and Disley, do fall in Cheshire East, which is why we always anchor a project to the council boundary rather than the postcode alone.
It may. Stockport has 37 conservation areas, and some are covered by Article 4 Directions. Where one applies, planning permission may be needed for replacement windows and doors, roof and chimney alterations, boundary walls, gates, and railings, and changes to elevations fronting a highway, waterway, or public open space — including swapping timber windows for uPVC. Not every conservation area carries Article 4 controls, so the specific property is checked against Stockport Council's current records at feasibility, before any external alterations are specified.
It means the policy context needs checking rather than assuming. Stockport's last adopted Local Plan dates from 2011, and in September 2025 the government issued a Local Plan intervention letter directing the council to progress an updated plan. Policies can change as that work moves forward, so for larger extensions, replacement dwellings, new builds, and commercial schemes, we review the council's current Local Plan documents, policies map, and live planning guidance at feasibility with your architect, before design time is committed.
Often, on Stockport's terraced and semi-detached streets. The Party Wall etc. Act 1996 applies when you build on the boundary line, cut into or alter a shared wall — for example to seat a steel beam or remove a chimney breast — or excavate within 3 or 6 metres of a neighbour's building, depending on depth. Notice has to be served one or two months before work starts, depending on the work. It is procedural, not optional, and separate from planning and Building Regulations, so we build it into the programme.
Yes. The JNR model is design-to-build partnership, not design-versus-build adversarial. We engage at RIBA Stage 2 or 3 — before drawings are finalised — with a constructability review, structural feedback, a planning and heritage risk assessment, and an early cost plan. We then contract under JCT and deliver as Principal Contractor under CDM 2015, building to specification without unauthorised material substitution. A dedicated project manager runs the site, the programme, and communication with neighbours. The architect retains design authorship throughout, and we never value-engineer a design without instruction.
Whether your architect’s drawings are ready, planning consent is in hand, or you simply have a Stockport address and an ambition to test against reality — a 20-minute conversation with Julian is where every JNR project begins.
