Project Overview
Project Context
The Marcus Hotel is a five-storey refurbishment and façade transformation project located on Main Street, Portrush. The development forms part of a wider regeneration of the town’s hospitality offering, with the building reopening under the Hilton brand as a high-end coastal destination.
Thornton was appointed on a contractor-designed portion basis to deliver the rainscreen façade. The brief was to create a distinctive architectural identity using a shingle-style façade, while ensuring the building could perform in a highly exposed marine environment. The programme was driven by a fixed completion date ahead of the 2025 Royal Portrush Open Championship, requiring careful planning and delivery.
Scope of Works
The works comprised the design, fabrication, and installation of a fibre-cement rainscreen façade system, including all supporting components and bespoke aluminium elements.
The façade was formed using Equitone Natura fibre-cement shingles fixed to an aluminium subframe system. The build-up included an SFS backing structure with cementitious sheathing board, Tyvek FireCurb breather membrane, Fixfast SPIDI bracket system with thermal break pads, aluminium rails and tophats, and Rockwool Duo Slab mineral wool insulation.
Cavity barriers were installed both vertically and horizontally to achieve compartmentation requirements, and the façade incorporated a drained and ventilated cavity to manage moisture and pressure equalisation.
A key element of the scope was the design and fabrication of bespoke aluminium trims and window pods. These projected through the façade and formed a defining architectural feature, requiring close coordination with the shingle layout and surrounding interfaces.
All elements, including window interfaces, parapets, and façade transitions, were developed as part of the contractor-designed portion to ensure a fully integrated envelope solution.

Key Challenges & Solutions
The building geometry presented immediate challenges. A cranked top-storey façade required bespoke solutions to maintain the intended appearance. This was addressed through the design of tapered and curved aluminium window pods, including a rolled curved dormer unit. These were measured on site and fabricated off-site to ensure accuracy, then installed as complete units to maintain consistency.
The façade itself required a high level of precision. The shingle arrangement was unforgiving, with even small deviations in alignment becoming visually obvious. A strict grid system was established using laser control lines, and significant time was taken at set-out stage to ensure alignment across all elevations. Shingles were factory cut, labelled, and sequenced prior to installation.
The marine location introduced additional exposure to wind and corrosion. Material selection was critical. Fibre-cement shingles were chosen to avoid corrosion issues associated with metallic systems, and fixing requirements were developed in line with project-specific wind load data. The subframe incorporated thermal break pads and a ventilated cavity to manage both thermal performance and moisture movement.
Programme was another key pressure. The requirement to complete ahead of the Open Championship created a fixed end date, with no tolerance for delay. Installation was impacted by coastal weather conditions, so sequencing was adjusted to prioritise accessible elevations and maintain progress where possible. Close coordination with the main contractor allowed recovery measures, including extended working periods, to be implemented where required.
Logistics and access were also constrained. The site sat within a live town environment with limited storage and shared scaffold access. Materials were delivered in phases, and installation was coordinated closely with other trades to avoid congestion and maintain workflow.
Performance Outcomes
The completed façade delivers a durable and fully non-combustible envelope suited to a coastal environment, meeting the required fire, thermal, and weathering performance standards.
The shingle façade achieves the intended architectural effect, with consistent alignment across all elevations and seamless integration of window pods and façade features. The use of off-site fabrication and controlled installation methods ensured quality was maintained throughout.
Despite the constraints of refurbishment, weather exposure, and a fixed completion deadline, the works were delivered in line with programme. The building was completed in time for the 2025 Royal Portrush Open Championship, providing a finished development aligned with the architectural vision of the client.
