Flagship heritage scheme blends 18th-century industrial character with 21st-century precision construction.

One of Leeds’ oldest surviving textile mills is being brought back to life, as Henley Restoration and Remedials Ltd takes the lead on an ambitious restoration and structural transformation of Midland Mill. Built in 1793 and originally known as the Midland Junction Foundry, the Grade II listed building is a rare survivor of the city’s industrial past.

Now forming a central part of the Sky Gardens masterplan, itself a key component of the South Bank regeneration zone, the project aims to retain the mill’s historical fabric while structurally future-proofing it for modern use. It’s a rare and carefully balanced convergence of urban renewal and heritage-led precision construction.

The appointment of Henley Restoration and Remedials Ltd as principal contractor was confirmed by City Life Developments Ltd, who cited the firm’s in-house expertise and longstanding heritage credentials as key to the decision.

“This is a flagship heritage project and a major undertaking,” said Tom Cardoe, Managing Director – Restoration at Henley Construction Management Group.
“Our role isn’t just to preserve the past; it is to engineer it for the future. That is where Henley sets itself apart: we plan, we build, we restore – all in-house.”

Survey-driven precision and structural sensitivity

Works began with a high-resolution 3D photogrammetry survey, forming the basis for a precisely coordinated restoration programme. Several historic elevations are being carefully dismantled and rebuilt, with engineered temporary works designed to support both safety and conservation standards throughout the build.

In a notable example of in-house capability, bespoke stainless steel components for structural reinforcement are being fabricated by Henley’s sister company, HZS Stainless Steel Ltd, and will be integrated directly into the original timber, masonry and concrete structure. This approach ensures both long-term stability and architectural discretion.

One of the most significant features of the project is the complete replacement of the roof. A newly fabricated steel structure will be installed and topped with natural slate, discreetly integrated with solar PV tiles. In a first for many listed building projects of this nature, the solar installation is expected to generate over 40,000 kWh of renewable energy each year – combining sustainability with architectural sensitivity.

Craftsmanship at every level

Externally, the historic masonry will be cleaned using Therm-atec steam technology, a gentle and non-invasive cleaning method that lifts decades of carbon and grime while preserving the integrity of the material beneath. Extensive lime mortar repointing will restore breathability to the external fabric.

The windows will be carefully reinstated using bespoke timber sashes and Georgian profiles, made to match the original detailing. Wherever possible, materials will be reclaimed or faithfully replicated to ensure complete heritage fidelity.

The entire project is being delivered through Henley’s integrated model, drawing on resources from across the Henley Construction Management Group, including Henley Brickwork, Henley Rail, and Henley Stone Specialists Ltd.

“Appointing Henley Restoration and Remedials Ltd was an easy decision,” said Gareth Morgan, Managing Director at City Life Developments.
“Their attention to detail, in-house capability, and deep respect for heritage made them the natural choice. Midland Mill is at the heart of our Sky Gardens scheme, and we’re excited to see it restored as a symbol of Leeds’ evolving future.”

Reviving industrial identity through Heritage Construction

With decades of expertise in historic buildings and conservation-led design, Henley’s appointment is a significant milestone not just for the project but for Leeds’ broader regeneration efforts. The restored Midland Mill is expected to become a defining landmark of the new South Bank quarter – bridging the city’s industrial legacy with its contemporary aspirations.

“This project represents everything we stand for,” said Shaun Henley, Managing Director of Henley Construction Management Group.

“Precision, passion, and a commitment to safeguarding the UK’s built heritage. We’re proud to be trusted with such a meaningful part of Leeds’ urban story.”

As the restoration progresses, Midland Mill will once again become a focal point of the Leeds skyline – proof that heritage and innovation can, when carefully handled, go hand in hand. Henley Restoration and Remedials invites the wider heritage construction community to follow the project’s journey as the mill reclaims its place at the heart of the city.
