Selling an architect-designed house in southern Finistère
An architect-designed house sells on a design, a light and a relationship to its site that no other house reproduces. It attracts a specific buyer, often already looking for this kind of property, and requires a fuller technical file than an ordinary house. This page brings together what to prepare, and the market figures for large houses in southern Finistère.
What drives the value of an architect-designed house
The quality of the design and its execution, the light, the relationship to the land and the view, the materials and how they age, the real energy performance, and whether the house can be lived in without altering it. The architect’s name matters to some buyers, especially if the house has been published or awarded. A recent house also keeps its ten-year structural guarantees, which pass to the buyer.
The technical file to gather
Working drawings, the building permit and its certificate of compliance, the completion statement, the building-damage insurance and ten-year guarantees still running, equipment manuals, thermal studies and the energy performance certificate. For a house under ten years old, these documents are part of the value: gather them before the first visit.
Who buys a contemporary house in Brittany
Buyers who refuse works and want a house ready to live in, architecture enthusiasts, foreign buyers used to modern homes, and families settling year-round. They compare with the cost of building: land, fees, delays. A finished house on a plot that can no longer be found often wins.
Presenting an architect-designed house
It is presented as a work: professional photographs at the right hours, readable plans, a few lines on the architectural intent and the architect’s name with their consent. Ti Kaer publishes these dossiers in French and English, or keeps them for registered buyers if the owner prefers discretion.

Questions
How much is an architect-designed house worth in Finistère?
It compares with sales of large houses in its town, published above, and with the cost of building the equivalent today. A recent, finished house on a plot with a view sits at the top of the local scale; its precise value is established after a visit.
Should the architect’s name be mentioned?
Yes if the house has been published or awarded, with the architect’s consent, as they keep moral rights over their work. It interests some buyers and sets the file apart.
Do the ten-year guarantees transfer?
Yes. Guarantees attached to the construction follow the house, not the owner. Their existence and remaining term are part of the sale file.
How do I sell a contemporary house without an advert?
By presenting it to registered buyers whose search matches, after qualification, with no publication. Ti Kaer’s buyers’ list receives searches for contemporary houses and architect-designed villas.
