Developers have revealed more details about a huge overhaul of High Wycombe's iconic Brunel engine shed - and shown us what it currently looks like inside.

The historic shed - which is Grade II listed and was designed by Victorian engineer Isambard Kingdom Brunel in 1854 - has been left empty and dilapidated for years, but will be revamped.

The then-Wycombe District Council bought the shed, which is the first thing you see when you step out of High Wycombe railway station, from Chiltern Railways last year.

Exciting plans to turn it into shops, offices and cafes were given the green light last month.

Now, developers Hawkins/Brown have revealed more details and drawings showing how it will look once finished - and even given residents a glimpse inside the structure as it looks now.

They say their "sensitive" refurbishment will help "breathe new life" into the iconic building - but will include materials found on site.

The planned new extension will be made with zinc cladding, while railway sleepers and original timber trusses will be reused throughout the building to reflect its history.

Hawkins/Brown said the shed will have a "welcoming new main entrance" facing High Wycombe railway station, with improved landscaping, a new roof which will "restore the original character" of the building, and a mezzanine level that will be fully accessible with a lift.

Cllr Katrina Wood, deputy leader of the new Buckinghamshire Council and former leader of Wycombe District Council, said: “A key focus for Buckinghamshire Council is working with and in support of businesses to grow the local economy.

"Wycombe District Council took a proactive and popular step to buy and develop this site for the benefit of High Wycombe.

"Hawkins\Brown have provided an appealing design that will make this an iconic first view of the town, an attractive opportunity for the right tenants and an exciting step in the regeneration of Wycombe’s Eastern Quarter.”

Hawkins/Brown is working with engineers Heyne Tillett Steel on the project.

Kelly Harrison, associate and timber lead at Heyne Tillett Steel, said: “The structure of the extension takes inspiration from Brunel's continuous pursuit of innovation and will use tapered sections of engineered timber to put material where the forces are highest, creating an extremely efficient and visually expressive design.

“Restoring the existing fabric is a wonderful challenge.

"The existing timber is in great condition for its age and we are able to re-use previously demolished truss sections, which have been stored in the building, to repair the roof where needed."

And Xuhong Zheng, architect at Hawkins\Brown, added: “High Wycombe’s Brunel Shed is a significant piece of Britain’s industrial heritage, a local landmark and an important gateway to the town for all users of the train station.

"Hawkins\Brown’s design will bring this disused shed back into use and activate its significant site as an anchor for the wider economic regeneration of the eastern district of High Wycombe.”
