The Explore Building

Before construction began, archeologists surveyed our site and found traces of a dock wall believed to be several centuries old, foundations of Victorian factory buildings and cobbled street paving. We were able to record these findings before covering them for digs in the next millennium!

The dock wall is believed to have kept spring water in, as well as dock water out, which is why land around the dock is 1 metre higher than in the dock itself.

The Explore building incorporates an existing heritage building into its innovative design is itself an exhibit.  It was designed by Wilkinson Eyre architects who took the Grade I I listed Great Western Railway goods shed and fused old with new to create a magnificent new exhibition space.

Explore Construction

The old goods shed was built by Great western railway in 1903 and is one of the earliest reinforced concrete buildings in the UK. It has the French Hennebique style construction which supports the elegant wide arches that once spanned the railway tracks. Small cross sections have deliberately been exposed in the stairwells to show the structure of the reinforced concrete using just four metal bars.

The architects added a 9 meter high and 90 meter long glass wall along the north side of the original building and a 15-meter diameter stainless steel planetarium sphere to the south side, which houses our dazzling new world of sensory experiences.

An interesting feature of the explore building is the  Eutectic tank, designed to act as an environmentally-friendly buffer to keep temperatures even within the building.

The tank consists of a ten meter transparent tower full of balls containing special eutectic salts.

As the temperature in the building rises - either because of visitor numbers or because it is hot outside - the crystals inside the balls begin to melt, taking in heat as they do so and cooling the building. As the building cools, the crystals turn solid again and give out heat.
