Nucleus Repurposing: New life for a design standard original

01

Introduction

Once a bold blueprint for modernising UK healthcare infrastructure, the Nucleus hospital design emerged in the 1980s as a modular, cost-effective solution to streamline construction and increase flexibility. The designs promised adaptable clinical spaces and rapid deployment – and they delivered. Today however many of these buildings show their age—burdened by outdated layouts, inflexible structures, and limited digital integration. Their original promise of scalability is at odds with the complexities of contemporary medicine, leaving them strained in delivering high-tech, patient-centred care.

But with over 100 of these hospitals still in existence across the country, an innovative and sustainable approach is needed to efficiently re-use and update for modern service delivery.

Murphy Philipps, as part of an IHP consortium directed by NHS England have developed a Standard Platform solution to re-use these template designs. With structural input from Perega, and services design by TB&A the aims are to provide a standardised Nucleus update. The output being a ‘Proof of Concept’ aligning with Government and NHSE objectives on MMC and Net Carbon Zero. A big focus therefore is utilising a kit of parts, such as layout, room, assemblies and components.

Challenges

To understand the primary issues, research was carried out with 34 Trusts.  The outcome of which drew some compelling conclusions

  • 51% of respondents have considered repurposing their Nucleus buildings
  • 100% of respondents support a standardised/programmatic solution
  • Between 40-53% of Nucleus estate surveyed requires investment due to:
  1. Physical condition (53%)
  2. Functional suitability (40%)
  3. Utilisation of space (45%)
  4. Quality of the building (41%)
  5. Compliance with H&S and fire regulations (43%)

Some of the key physical constraints include:

  • The 1000sqm cruciform floor is 10% smaller than a 50% single-bed ward and 18–20% smaller than full single-bed provision.
  • Limited floor-to-floor height complicates some uses – eg: ICU
  • Designs are based on horizontal escape routes between wings, restricting layout changes.
  • Central spine columns in each cruciform wing mean circulation routes need to be maintained, hampering possible efficiency alterations
  • Carrying out construction work adjacent to live clinical environments requires more expertise and forward planning to minimise service disruption

Conservative estimates, suggests around 1,020,000m² of Nucleus accommodation exists across approximately 100 hospitals in England.  This equates to around 5 wings per hospital.

Opportunities

Initial studies were based on the original Nucleus template at Newham University Hospital - an archetypal design. The Proof of Concept seeks to establish viability of an Inpatient Ward, with HBN compliant options, and wider block impact by:

  • Generating General Arrangement, MEP, structural layouts and outline fire strategy
  • Structural capacity studies for additional accommodation/plant and services opportunities for additional M&E plant and duct routes
  • Identifying derogations and highlighting areas of risk

MMC solutions support the kit of parts approach such as.

  • Standardised and repeatable rooms, for example bed bays and typical isolation units
  • Standard grid arrangement and window sizes enabling off site façade fabrication as part of refurbishments.
  • Prefabricated external riser kits

Our Inpatient review/Proof of Concept demonstrates that not only can a new compliant ward be housed successfully within the footprint of a Nucleus cruciform, but a full Nucleus block can be updated to support inpatient accommodation from a structural, MEP cost and delivery point of view also.

Alongside the ward study, outpatients, ICU Ward, and Imaging were all reviewed as part of the repurposing exercise

The standardised solution:

  • Delivers upgraded accommodation at scale and at speed, addressing backlogs in maintenance and patient wait times
  • Promotes sustainability through reduced embedded carbon helping meet site NZC targets
  • Delivers an overall programme saving of 57 weeks, which is approximately 35% quicker than a new build solution.
  • Reuses the existing structure, providing a 90% saving on the embodied carbon of the structure compared to new build.
  • Can be phased to help reduce on site time, and manage disruption

Where next?

The proof-of-concept study that has been carried out would assist in streamlining the design process and could provide a route to fast-track approvals. Based on information received from other Nucleus hospitals, common strategies can be implemented with minor variations due to differences in footprint and GIA. A light refurb refurbishment model could provide a 10–20-year extension of working life, with a full refurbishment model offering potentially a 50-year extension.

A programmatic and standard approach is the obvious solution to refurbishing the modular, standardised nucleus model, and almost 35 years after the last hospitals were built under this programme we can look to modern construction practices to deliver this in an efficient way.
