Plans have been to lodged to redevelop a former tyre factory complex in north Birmingham which was brought back to life as a mixed-use scheme a decade ago.

Tristan Capital, which acquired Fort Dunlop in Castle Bromwich last year, is planning the first major renovation and development work there since it was re-opened in 2006 following a major regeneration by Urban Splash.

Among the planned projects are an increase in parking and enclosed conference facilities on the roof of the 375,000 sq ft complex and, pending planning approval, work is expected to start early next year.

Fort Dunlop, near junction 5 of the M6, was originally designed by Sidney Stott and WW Gibbings and opened in the 1920s but closed down during the 1980s after which it lay dormant for two decades.

Neil Edginton, director of EDG Property which is leading the renovation work on behalf of Tristan Capital, said: "Fort Dunlop has always been a landmark site, our occupancy levels are demonstrative of that.

"These plans are about taking this recognisable scheme and enhancing it, improving the experience for people who work here on a daily basis and bringing new visitors and tenants to Fort Dunlop.

"We have some real USPs here, with the location just off the M6, and of course, our roof, and we're confident the work planned will take Fort Dunlop to the next level in terms of its offering."

The redevelopment work will see an additional 500 parking spaces added to the site with 45 going in front of the Travelodge hotel and a single decked level added to the surface car park.

There will be two new garden walkways in a bid to improve public realm in front of the building, in Fort Parkway, while the Travelodge will undergo its first facelift since opening including a new reception area and food and beverage facilities.

Plans have also been submitted for the creation of a conference centre on the roof, with the proposed glass structure enabling users to make the most of the views available atop the building.

Plans also include new kitchens, outdoor seating and a landscaped area.

Fort Dunlop has already undergone some renovation work earlier this year including a new reception area with digital wall and touch-screen tenant directory and space for two additional units for food and beverage operators to join existing tenants Scoff and Duet.

A new logo and website was also recently launched and events such as a street food festival and hot tub cinema club on the roof have also recently been held.

Three owls from the city's Big Hoot art project are also currently based at Fort Dunlop.

The building is currently 90 per cent let and tenants include the Birmingham Post and Mail, budget gym chain 24/7 Fitness, upmarket kitchen brand Poggenpohl and cycling store Specialized.

Building manager is Capital Properties and joint letting agencies are Colliers and Bilfinger GVA.
