Noss Head Lighthouse, Scotland
Noss Head Lighthouse transformation – engineering differently on Scotland’s coast
Project overview
Transforming a historic lighthouse into a contemporary home is no ordinary brief and exactly the kind of challenge that defines a forward-thinking structural engineering company. We were appointed as structural engineer consultants on this 1849 lighthouse at Noss Head, near Wick in the far north of Scotland to transform it into a modern, open plan coastal residence while respecting its heritage and extreme environment.
Project: Noss Head Lighthouse residential conversion
Location: Noss Head Lighthouse, near Wick, Caithness, Scotland approximately 30km south of John o’ Groats
Client: Private owner
Engineer: dbstructural chartered structural engineers
A historic landmark reimagined
Originally constructed in 1849, Noss Head Lighthouse stands on land once owned by the Earls of Caithness. It was then acquired by the Northern Lighthouse Board in the mid 1800s.
Designed by engineer Alan Stevenson and built by Mr Arnot of Inverness, the site stands the ruins of Sinclair Girnigoe Castle, overlooking the North Sea.
The lighthouse transferred into private ownership in 2017.
Dbstructural’s residential structural engineers were consulted by the current owner to assist with the structural design of alterations and extensions to the original dwellings at the foot of the lighthouse, which originally housed the principal and assistant keepers.
Structural challenges on an exposed coastal site
Operating as a structural engineer in Scotland, this project demanded careful consideration of exposure and in line with Scottish planning requirements. Positioned on a cliff edge, the building is subjected to some of the harshest wind and snow loads in the UK.
Key elements of the design included:
- Internal wall removals to create open plan living spaces
- A single storey side extension with vaulted ceilings
- Large, glazed windows framing panoramic views over the North Sea.
While the original structure utilised a concrete roof to resist wind uplift, the proposed extension introduced a significant design shift.
Engineering for snow and wind loads
Given the geographical and highly exposed cliff edge location of this development, the main design factors to overcome were the snow and wind loads applied to the structure.
The original building has a concrete roof and it was proposed to replicate this in the extension due to the benefits of additional mass to resist wind uplift. However, during the design development phase, the architectural vision moved toward a lightweight timber roof structure, creating a key engineering challenge.
However, through design development with the architect a timber roof was insisted upon. This created a challenge for us to overcome in terms of holding the roof down under extreme wind conditions.
As chartered structural engineers, our responsibility was to ensure the new roof could withstand extreme uplift forces without compromising the architectural intent.
Through detailed calculations and refined structural detailing, we developed a solution that:
- Anchored the timber roof effectively against high wind loads
- Maintained structural integrity in extreme weather conditions
- Delivered the clean aesthetic sought
This is where a truly collaborative structural engineer consultant approach proved invaluable, aligning design ambition with structural performance.
Engineer insight
Our Senior Engineer James worked on this project. He commented: “This project was something different from the norm, mainly because of the nature of the existing building, the North Scotland location and the high snow and wind loads that brings.
“It was time to delve deep into the design codes to check the wind and snow loads by hand and when the roof structure was changed to timber it really was time to sharpen the pencil. However, with some sensible detailing we were able to overcome this challenge. Definitely a sleepless night or two with this, but great to see the project finished!”
The result
The completed transformation delivered a unique coastal home that blends historic character with contemporary living. Stunning uninterrupted views of the North Sea, while the structural design ensures resilience against the elements.
