Selling a loft or an unusual property in southern Finistère
The ports and towns of southern Finistère have left canneries, workshops, warehouses, chapels and schools that have become homes. These properties sell neither per square metre nor by direct comparison: they find a buyer who was looking for exactly that. This page brings together what an owner needs to prepare, and the figures for sales of large houses in the towns concerned.
What drives the value of an unusual property
Volume and light, location, the quality of the conversion and, above all, its legality: an authorised change of use, a compliant permit, insurance in order. A loft whose residential use was never declared sells badly and is hard to finance. Rarity cuts both ways: few competitors, but few buyers.
Change of use and planning
Converting a workshop, a warehouse or a place of worship into a home is a change of use that requires planning authorisation. Before the sale, gather the authorisation obtained and the completion statement, or have the situation regularised. The notaire and the buyer’s bank will ask for them. In a heritage area or near a monument, the heritage architect’s opinion may have been required.
Who buys a loft in Brittany
Buyers from large cities used to industrial volumes, makers, professionals looking for a studio and a home, foreign buyers. They look at insulation, heating of large volumes, acoustics and parking before charm.
Presenting an unusual property
An unusual property sells on its story and its volumes. A dimensioned plan, photographs that show scale, the history of the place and its conversion, and the list of authorisations obtained make up the file. Ti Kaer presents these properties in French and English, publicly or to registered buyers only.

Questions
How is a loft or unusual property valued?
By three crossed approaches: sales of large houses in the town, published above; the cost of reproducing the volumes and the conversion; and the actual demand from registered buyers for this kind of property. The value is confirmed after a visit.
Can a loft be sold without an authorised change of use?
It can, but badly: the buyer and their bank will require residential use to be lawful. Better to regularise before selling, with an architect or a planner.
What surveys for a former industrial building?
The same as for a house, with particular attention to asbestos, common in industrial buildings before 1997, to lead in old paint and to soil condition where there was a past activity.
