Haynes International Motor Museum will unveil the first phase of its multi-million pound redevelopment in Spring 2014.

The revamp includes new exhibitions, display halls, café, shop, expansive conferencing and banqueting suites, and will provide a new façade to the museum.

The project has been privately funded by founder and chair John Haynes, who opened the museum with just 33 cars, housed in one hall, in July 1985.

Phase one, set to open this April, will reveal the first new exhibition area, nicknamed ‘The Black Box’ due to its exterior.

The Black Box, a two-storey display area, overlooks the Haynes’ test track and is divided into two parts – The Vroom Room on the ground floor and The Motorcycle Mezzanine on the upper.

The Vroom Room, spanning more than 3,875sq ft (360sq m) and accommodating around 18 to 20 cars, is dedicated to high powered, high performance sports cars, while the Motorcycle Mezzanine will create a permanent home for the museum’s two-wheeled collection of around 70 motorbikes from around the world.

Prior to the opening of the new exhibition halls, Haynes will reveal a £250,000 new family entertainment zone in the museum’s grounds called Haynes Motorland, featuring a 16,145sq ft (1,500sq m) adventure playground with a range of motoring themed interactive games and miniature vehicles for children.

There will also be two classic buses – one featuring a cinema and the other a soft play area - and a new go-kart circuit known as ‘Haynes Hatch’ with battery operated vehicles.

Managing director Marc Haynes said: “ We are looking to create a visitor experience that appeals to all the senses, which includes bringing some vehicles outdoors so we

can fire up the engines allowing visitors to hear and smell the motoring heritage as well as admiring the 400 vehicles on display.”

The second phase will include the remodelling of the other display halls as well as a new museum frontage that will mark the start of the visitors’ journey around the venue.
