Product category :

Demountability in architecture concerns the ability of a building, a construction system, an assembly to be demountable, suitable for deconstruction.

An ideal demountable building is characterized by the possibility of being taken apart and reassembled or reused over and over again.

Construction and exploitation costs

• Total cost of the building : 68 619 €

Reuse : same function or different function

Batches concerned by reuse :
• Indoor joineries
• Outdoor joineries
• Partitions
• Electricity
• Landscaping
• others...

For each batch : Reused Materials / Products / Equipments :

Items made for reuse:

• 10 exterior joinery including 9 second-hand resulting from careful dismantling, order errors and exhibits (see plan of joinery). Lot 2680€ transport included (+1350€ installation in total);
• the interior carpentry : for example the two kitchen worktops made of two medium slabs recovered from a material library, as well as the second-hand tiling that covers them, or the washbasin in the shower room made of trespa (fall facade and therefore waterproof) + vanity unit based on an old chest of drawers. We can also mention skirting boards from a construction surplus (40ml). Batch 190€ transport included;
• electrical equipment, i.e. all switches, sockets and light fixtures. Batch 10€ transport included;
• the terrace , more specifically the wooden slats up to 40m² collected (via le bon coin), cleaned, cut and turned over to be reworked for 32m², to the south and north. Batch 150€ transport included;
• the wall and ceiling covering comes from the 2017 architecture biennial (Atelier Utopies) which took place at the Sucrière in Lyon. The implementation of the scenography having been considered upstream as "non-destructive", the planks and wooden cleats were tied by rope. Thus, they were virgin and suitable for reuse. They are 100u in number. of pine panels (2000 mm x 500 mm x 18 mm thick) and cover all the peripheral walls of the house as well as the ceilings of the 3 rooms. In order to limit falls, the layout has been made according to their size, drastically limiting falls. Batch 350€ transport included;
• the frameworks of the partitions and the joists are from the same sourcing as the pine panels. They are 85u in number. of pine cleats (32 mm x 45 mm x 4500 mm). They receive the panels of the walls, the ceilings and the solid parquet floor, while offering the adequate technical space for the passage of the networks. Batch 400€ transport included;
• the stove and its floor plate , acquired second-hand in the village of Silhac, from an acquaintance. I acquired the smallest that I found used (by an acquaintance) so as not to over-consume. It is 4kw and I spend a cubic meter of wood per year (my neighbor cuts it, dries it then cuts it for me) to heat the volume during the cold period. Batch 330€ including transport (+1500€ of installation in total with supply conduit and exit in roof);
• the sanitary elements , which are the washbasin, the kitchen sink, the fittings from private individuals Le Bon Coin. Batch 110€ transport included;
• the ventilation grilles / air inlets from a private Le Bon Coin. Batch 30€ transport included;
• the paint on the walls comes from the bottoms of pots of professional painters. Batch 10€ transport included;
• furniture and household appliances , in their entirety (sofa, desk, chairs, tables, bed, oven, fridge, hotplates, dishwasher, etc.) from private individuals at Le Bon Coin. Batch 2600€ transport included;
• the development of the exteriors , in particular the exterior staircase in mixed technique: high steps in chestnut beams from the deconstruction of an inn in the neighboring village and low steps in stones from the land, from fallen dry stone walls. The already-there takes on its full meaning. We can add the work currently in progress which is a wooden fence in bastaings resulting from a deconstruction site of a French-style wooden slab and the installation of 3 water recovery tanks (1000L each). Batch 200€ transport included;

The reuse operation saved the equivalent of 77,322 kilometers traveled by a small car, i.e. 88 Paris-Nice journeys, 4,981 rectangular bathtubs filled with water and 28 years of household waste for a Frenchman

In the calculation of avoided impacts, I was not able to take into account:

• the stove and its floor plate;
• elements complementary to external work (screws, ropes, etc.)
• some furniture such as the dresser in the shower room, the bed, the sofa and all the other small pieces of furniture / decorative elements in the cabin;

And I counted the 100m² of interior wooden wall and ceiling panels in the category of reconstituted wooden false ceiling (in the absence of another more suitable category). Also, I counted the 85u of cleats and the 40ml of pinths under the wood frame category (in the absence of another more suitable category there too).

Economic assessment

• Total cost of reuse : 7 056 €
• Cost of reuse in percentage of the operation : 10 %
