Urban Patterns is a typology of some of the practice towers used by the London Fire Brigade. The designs of these structures follow a limited number of patters that are repeated in many of the city’s fire stations. Selecting tow of these designs, I have photographed them to emphasise the sameness of the structures. We are therefore confronted with objects observed by all who live in the city but perhaps rarely connected in this way. At the same moment that the connection is made, we seem to doubt whether these structures are real – have the images been manipulated to give the appearance that these structures are duplicated, or have we simply never noticed the duplication before?​
