Common Swifts usually look
for nest places in the places where their experience tells them nest
sites might already exist, e.g. in the boxes of Venetian blinds, under
gutters or in the gaps between wall slabs. It is clearly useful to
exploit this tendency and install new nest boxes in places they are
naturally inclined to use. However, Swifts can and do detect new nesting
possibilities in untypical sites.

One can install nest
boxes, or prepare nest holes from about 3m high upwards. In Paris,
France, Common Swifts breed in a hole about 70m high in the 26th floor
of a tower block. The direction the nest faces is not of much
importance. Take care to maintain ample free space in front of the entry
hole of the nest box so that the Swifts can enter the hole in direct
flight.
