About Our Company

CSUK are commercial interior design & mezzanine floor experts based in Bournemouth and Poole, offering services nationwide. As the UK’s most dedicated interior contractors, we specialise in mezzanine floors, modular construction, commercial fit outs & refurbishments, and can offer the complete solution from bespoke interior architectural design to fabrication and fit out. We design, build and refurbish interiors for a range of industries from hospitality & commercial kitchens, retail, industrial, residential, offices & medical spaces. All our services are made to industry standards, using the British Design Codes and SEMA Code of Practice.

CICS was incorporated in 2017 by our founder Nathan Roach, who had been working in the industry for 6 years before deciding to set up his own business. The first company project was one of Nathan’s biggest where he designed, resourced, project managed and built the first large dark kitchen site in Shoreditch, London. CICS designed and fabricated the mezzanine floor along with full interior fit out for 24 dark kitchens. The build took us 6 months and exercised every service Nathan had envisioned for the new business providing the turn key solution for commercial fit out projects.

At the start of 2018, we launched our own in house fabrication unit and setup our office in the same location to oversee the metal works before they landed on site. Nathan continued to design and build further dark kitchen sites for the same client across all areas of London whilst maintaining a further customer base of over 20 clients which had emerged from advertising and word of mouth.

2019 was an exciting year for Nathan as he was tasked to develop a new modular construction method for building dark kitchens across the world. He designed and developed the very first modular dark kitchen to be retrofitted into a building in his factory in Bournemouth and went on to sell £2million worth of kitchens to an American company who were investing the UK property market. Meanwhile, the mezzanine floor arm was booming and collectively as a group we grew to over 50 members in the team consisting of carpenters, plumbers, electricians, painters, steel erectors, labourers, dry liners, mechanical and duct work fitters, line managers, interior architects and factory managers.

Here is Nathan below along with some photos of the team in our Bournemouth location working on the modular rooms.
