The building was designed in Gothic Revival style by Edmund Woodthorpe, and stands at 1 Leysfield Road, close to Ravenscourt Park.

In 1961 the church was bought by the Polish Catholic Mission to the United Kingdom, with a mortgage, paid off in time with the help of donations and legacies from the faithful.

The Bobola congregation in West London was initially made up largely of people who had survived the trials of Siberia during and after World War II.

[4] Despite an "uneventful" exterior, the interior of the church was, according to Bridget Cherry, "daringly modernised" by émigré Polish craftsmen and artists under the direction of designer Aleksander Klecki.

He had been aboard the Polish Airforce Russian-built Tupolev Tu-154 aircraft carrying the delegation of notable Poles intending to visit the Katyn site on the 70th anniversary of the Massacre, when the plane crashed near the Russian city of Smolensk.

On 23 April 1978 soil from the site of the Katyn massacre in Soviet-Russia was brought to the church and secreted inside its wall in commemoration of the 28,000 Polish Army Reserve officers of all faiths and members of the professions, who were murdered in 1940 on the orders of Stalin.
