JNR Construction delivers structural refurbishment, commercial fit-outs, adaptive reuse, and compliance-driven upgrades for landlords, business owners, and heritage commercial properties across Cheshire and Greater Manchester. Every project operates under the full CDM 2015 regime, with a dedicated Project Manager providing single-point accountability from pre-construction through to handover.
The stakes are different. Trading loss from programme overrun, regulatory liability from non-compliance, and reputational damage from a site that is not under control are consequences that residential projects rarely impose at the same scale.
Clients who come to JNR for commercial projects are typically landlords managing portfolio assets, business owners transforming a leased space, or trustees responsible for a heritage building with planning obligations attached. What they share is a low tolerance for ambiguity and a high requirement for a contractor they do not need to manage themselves.
JNR operates as Principal Contractor on commercial projects. This is not a title — it is a legal duty under Regulation 5 of CDM 2015, and it means a single organisation is formally accountable for the safety and governance of every contractor on your site, from the first day of strip-out to the day you receive the keys back.
Structural renovation requires engineering rigour applied to buildings where the existing structure is unknown until exposed. We survey, specify, and execute — without improvising solutions that compromise the programme or the structural integrity.
Commercial fit-outs involve coordinating M&E, partitioning, finishes, and commissioning within a live or time-critical building. We manage trade sequencing, access logistics, and sign-off against the specification with the same discipline as structural projects.
Changing a building’s use — from commercial to residential, pub to mixed-use, industrial to office — triggers a raft of Building Regulations requirements. We manage the compliance strategy from pre-application through to Completion Certificate.
Commercial projects carry a heavier regulatory burden than residential work, and the consequences of non-compliance are proportionately more serious.
Under CDM 2015, JNR Construction operates as Principal Contractor on all qualifying commercial projects — maintaining the Construction Phase Plan, coordinating health and safety governance across all trades, and handing over the statutory Health and Safety File at completion. This is a legal requirement under Regulation 5, not a quality-of-service enhancement.
The Building Regulations etc. (Amendment) (England) Regulations 2023, which implements the dutyholder regime introduced by the Building Safety Act, extends competence requirements to clients, Principal Designers, and Principal Contractors across a wider range of projects. Any commercial project of substance must now demonstrate that the relevant parties hold and can demonstrate appropriate competence — not merely assert it.
Heritage commercial buildings add a further layer. Listed Building Consent must be obtained for any works affecting the character of a listed building, and the scope of that consent reviewed against the specific design before any works commence. JNR has direct experience on Grade II listed commercial projects including The Angel Inn, Stockport, where traditional lime mortars, sash window reproductions, and Conservation Officer-approved methods were specified throughout.
A landmark Grade II Listed commercial restoration demanding strict Conservation Officer compliance throughout. The project involved full structural survey of the existing fabric, replacement of failed lintels and masonry using traditional lime mortars, sash window reproductions to match the original elevational detail, internal structural reconfiguration to meet modern Building Regulations while preserving the listed fabric, and formal Listed Building Consent administration throughout.
All works conducted under CDM 2015 with JNR appointed as Principal Contractor. The Heritage England notification procedure satisfied prior to commencement of works affecting listed fabric.

On commercial projects involving more than one contractor, the Construction (Design and Management) Regulations 2015 require a Principal Contractor to be formally appointed in writing by the client before construction commences. The Principal Contractor is responsible for planning, managing, and monitoring the construction phase, coordinating health and safety across all contractors, maintaining the Construction Phase Plan, and handing over the Health and Safety File at completion.
Unlike domestic projects, where CDM duties transfer automatically if no appointment is made, commercial clients retain the obligation to make the appointment themselves — a failure to do so does not release them from liability; it creates additional exposure.
A change of building use triggers a requirement for the new use to comply with the current Building Regulations as if the building were new, to the extent that it is reasonably practicable. In practice, this typically means: fire safety and means of escape assessed against the new occupancy type (Part B), structural adequacy reviewed for the new loadings (Part A), and energy performance assessed against Part L. A change of use from commercial to residential (Class C3) involves the most comprehensive compliance exercise, as residential use carries the highest fire and habitability standards.
Planning permission is required for most material changes of use, and prior approval for some residential conversions. JNR coordinates the full compliance strategy from pre-application through to Completion Certificate.
Yes. JNR has direct experience on Grade II listed commercial buildings including heritage pub restoration, requiring Conservation Officer engagement throughout, specification of traditional lime mortars and natural hydraulic lime renders, sash window reproductions to match original elevational detail, and formal Listed Building Consent administration.
Before any works affecting the listed fabric proceed, JNR reviews the Listed Building Consent conditions, confirms which elements are controlled, and obtains any required consents for variations. We do not substitute modern materials where the consent conditions or the building's physics require traditional ones.
Yes — this is the preferred structure for complex commercial projects. The architect maintains their Principal Designer role under CDM 2015, coordinating health and safety during the pre-construction phase and producing the pre-construction information. JNR steps in as Principal Contractor for the construction phase, providing a pre-construction buildability review, coordinating trades and CDM governance on site, and reporting progress against the programme to the architect and client. The cleaner the design team structure, the better the project outcome.
JNR delivers commercial construction projects across Cheshire and Greater Manchester, including Macclesfield, Stockport, Wilmslow, Knutsford, Congleton, Altrincham, and the surrounding areas. The nature of commercial project management means we assess each project on its merits and programme requirements rather than by geography.
Commercial projects have more moving parts, more regulatory weight, and more stakeholders than residential work. The contractor appointed at the start sets the tone for all of it. JNR Construction has been delivering commercial projects in Cheshire and Greater Manchester for over 20 years. If you have a project at any stage — from early feasibility to a full tender package — speak to us before you commit to a programme.
