Located on the “Flourish” at the south end of Lloyd George Avenue the Craft in the Bay Gallery consists of the refurbished “D” Shed, a grade II listed maritime warehouse together with a modern extension. The gallery is opposite the Wales Millennium Centre and close to the iconic Welsh Assembly Building.

The project took over five years to plan and was funded by sponsors including Arts and Heritage Lottery Boards; the European Regional Development Fund; Wales Tourist Board; various Charitable Trusts, including The Wright Trust and Garfield Weston Foundation; and members of the public and of the Makers Guild in Wales.The new premises were designed by Noel Architects and built by Mowlem South Wales.

The "D" Shed is a remarkable cast-iron framed structure with rare cruciform columns, an interesting roof structure and a variety of similarly unique features. The structure is five 20 foot bays long and two 20 foot bays wide. It was erected as a transit warehouse and appeared on the first edition Ordnance Survey map from surveys carried out in the 1880s. Originally sited alongside Bute East Dock Basin it was also served by rail. The “D Shed” is one of the last remaining mid-nineteenth century buildings in Cardiff Bay and has a grade II listing.

The use of iron frames ceased around 1880 with the introduction of steel rolling processes. Of particular interest are the wholly cast cruciform columns and the manner in which the eaves beams have been constructed out of simple available sections, riveted together to provide the strength required. Also of interest is the roof truss design including the bent bottom member and cast iron stays.

The listed building is used as an exhibition and craft retail area; it is sheer-glazed on two sides to provide views into the exhibition space. The extension was designed as a contrasting element and accommodates demonstration studios, meeting space, office and a café with a dramatic pointed roof projecting over an outside seating space.
