What does a change in use and/or scale in buildings imply? How can a church or chapel be transformed into a home? While the architecture of many contemporary sacred spaces shows a remarkable capacity for adaptation and evolution, the creative boundaries of many professionals extend beyond their conception as structures of spirituality or worship. Globally, the conversion of large churches and small chapels into private residences reveals a wide field for intervention and exploration, one that can preserve, restore, adapt, and/or renew the character of spaces originally conceived for other uses and scales, which for various reasons have been abandoned, become obsolete, or now require transformation.


As the demand for affordable housing grows and the availability of low-cost properties diminishes, stakeholders in housing must become more innovative in their approach to social housing development. One opportunity lies in restoring and repurposing abandoned buildings. While building new houses remains the primary strategy for Housing Authorities and Associations, rehabilitating derelict buildings can be a more economical option. This approach not only maximizes the use of dilapidating infrastructure but also provides an economic opportunity to increase affordable housing within the city. Although rehabilitating derelict residential buildings may seem like an obvious solution, it becomes even more crucial when considering abandoned commercial, institutional, or historical buildings for social housing.

Whether rising to the highest room of the tallest tower in a Disney-esque castle, giving an admirer the chance to confess their love on an apartment building fire escape, or connecting a basement or attic room with a decorative period feature, there’s something unavoidably romantic about spiral staircases. But there’s more function behind these coiling forms than just their good looks.
One common-held theory is that spiral staircases were first installed in historic castles as vertical baffles, tiring out enemy infiltrators before they could make it to the top. This is why – it is said – many are set to turn clockwise on the ascent, so attackers have a smaller arc for swinging weapons (mostly held in right hands) than defenders making their descent.
