Project Description

Bern Historical Museum was designed by Andre Lambert in 1894 in a revivalist style to recall the architecture, especially the castles, of the 15th and 16th centuries. Over time, the museum, which houses collections devoted to prehistoric material, folk art, ethnographic objects, and various kinds of decorative and applied art, found it had outgrown its size. To make the most of the limited land area available the extension has been built partly above and below ground level. the texture of the building’s walls and the varying angles of the concrete facades are designed to reflect the irregular construction of the original building.


Project Requirements

To create a modern extension building that would harmonize with the existing classically designed structure, including a new interpretation upon the traditional existing materials such as sandstone, plaster and stone. To this end, the color of the concrete played an important role in the construction.


Sika Solution

Sika AG Switzerland produced colored concrete samples for the architect to choose from prior to construction. Sika® Viscocrete® high range water reducing superplasticiser was included in the concrete mix together with Sika dry concrete pigment. Sika pigments were utilised to give the correct shades of color required.

Colored concrete is a durable and aesthetic solution for all modern architecture. It retains its color and resists mechanical damage.
