GMI’s South Shields Customs House refurbishment: design and access notes for engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
GMI Construction Group has been appointed via the NEPO Framework to refurbish South Shields’ Grade II listed Customs House, originally built in 1863 and now housing a 442-seat theatre and 132-seat studio/cinema. Works include internal reconfiguration, sensitive restoration of heritage fabric, and new extensions to deliver modern, fully accessible, multifunctional spaces for cultural, educational and commercial use. Key interventions feature an architectural glass entrance and an ‘internal street’ linking the main building to the adjacent Daltons Lane workshop, funded as part of South Tyneside Council’s £20m Levelling Up programme.
Technical Brief
- Contract let by South Tyneside Council via the NEPO Framework covering 12 North East authorities.
- Existing facilities include a 442-seat main theatre and 132-seat studio/cinema plus rehearsal and gallery spaces.
- Venue also incorporates a restaurant and private dining suite, affecting construction phasing and services diversions.
- Internal reconfiguration will need careful sequencing to maintain structural stability of historic masonry fabric.
- Sensitive restoration of key heritage elements implies specialist conservation trades and non-standard material specifications.
- Integration of Daltons Lane workshop via the ‘internal street’ introduces interface risks between two distinct structures.
Our Take
GMI Construction Group’s selection for the Customs House and Daltons Lane workshop follows its recent work on the Grade II* George Hotel in Huddersfield, signalling that councils are repeatedly turning to GMI for complex refurbishments of historic UK assets rather than just new-build logistics schemes.
The £20m Levelling Up Fund Round Three backing in South Shields aligns with other North East public-sector commissions in our database, suggesting South Tyneside Council can leverage established procurement routes like the NEPO Framework to move quickly from award to site mobilisation.
GMI’s recent profit improvement on flat turnover, alongside new cultural and industrial projects in Darlington and Ferrybridge, indicates the Customs House refurbishment will sit within a diversified workload, which typically reduces delivery risk for a single heritage scheme in the North East.
