Restoring a Liberty facade in Cit Turin: what is allowed and what it costs

Cit Turin has the densest run of Art Nouveau buildings in Italy, and a good proportion of them carry a formal protection order on the facade. That order is why the streets still look the way they do, and it is the first thing a buyer needs to understand about the cost of ownership here.

In practice a listed facade means three things. Anything visible from the street — windows, balcony railings, shutters, the colour of the render — needs authorisation from the Soprintendenza before it changes. Replacements have to match the original in material and profile, which rules out the standard PVC window unit that the rest of the market uses. And the timescale for authorisation is measured in months, not weeks.

On a 2024 project we advised on in Via Piffetti, the window replacement alone took eleven months from first application to installation. The units were made in larch to the original profile with slim double glazing, at roughly 2.6 times the cost of a standard replacement. The heat loss improvement was smaller than a modern unit would have given, but the building kept its face.

Internal works are a different matter and much more straightforward. Layout changes, services, bathrooms and kitchens are governed by the ordinary building rules, not the protection order, unless a specific internal element is separately listed — a painted ceiling, a decorative stair.

Our advice to buyers is simple. Budget the facade work at the building level, not the flat level: it comes to you as a condominium resolution and it comes whether you wanted it this year or not. Read five years of minutes. And if the building has already done its facade in the last decade, pay the premium for that flat, because the person selling it has already absorbed the cost you would otherwise be about to meet.
