Hämeenkylä Church, Vantaa, Finland

Designed by architect Olli Pekka Jokela and completed in 1992, Hämeenkylä Church in Vantaa, Finland was defined by its two main elevations, comprising a monolithic mass of pale yellow brickwork. But years of weather damage such as ‘frost wedging’ (the repeated freeze-thaw cycle of water within the masonry) or similar problems, perhaps made worse by the inclination of its tapered walls, left the brickwork beyond practicable repair.

The solution was a new external skin of pre-patinated copper, retaining the original architectural expression but with a fresh materiality and indefinite lifespan without maintenance.

A NEW SKIN OF PRE-PATINATED COPPER

A steel framework was constructed just in front of the failing brick walls, with pre- patinated copper cladding completely protecting the masonry from the weather while still allowing it to ‘breathe’. The new copper skin precisely follows the original inclined brickwork and fully accommodates the retained, original fenestration composition.

The pre-patinated copper provides a continuous surface to the monolithic form, relieved by close horizontal banding...

The impressive natural lighting into the building that characterises its original design and views out from the interior remain unaffected. The copper continues over a huge rectangular opening that announces the church entrance at the head of an approach ramp and the adjoining tower. The pre-patinated copper provides a continuous surface to the monolithic form, relieved by close horizontal banding, referencing the brickwork beneath.
