Urban environment

• Green space : 4 800,00

The development of a public garden within the Reuilly barracks is part of the larger project to transform and densify the site. This new public space participates in the opening of the former military site towards the district, stretching to the feet of the housing in a continuity between landscape and architecture. By opening up the former 'place d'armes' to its environment, the urban and landscaping allows to regain permeability with the city, but also to revitalize the ground floors on the street, occupied by shops or business premises. The barracks becomes a place open to the neighborhood, visited and crossed by a large public. The mineral plots created on the three lanes bordering the plot open access to the central garden. Their mineral treatment in reused pavers incorporates grassed joints and planted or existing trees. Very wooded, the public garden continues this pavement to promote crossing routes. Its undulations on the ground create a shifting topography that multiplies the uses and puts the accommodation on the ground floor, equipped with planted valleys, at a distance. A continuum of grass, flowers and scents accommodates a diversity of uses and audiences. The programming of the garden has been refined with local residents and future residents, with tailor-made seats, games for children and vegetable garden areas.

Construction and exploitation costs

• Total cost of the building : 104 800 000 €

Field of use and material origin :

PLUMBING PACKAGE - CAST IRON RADIATORS

• TRACEABILITY

Origin of the lot: all the existing buildings of the Reuilly barracks

Cleaning work: ATD

Reconditioning work: RADIASTYLE

The removed radiators were returned to the site after being transported to the company specialising in the reconfiguration of cast iron radiators, which was responsible for storage in the workshop and delivery to the site after reconditioning.

Area of use: plumbing.

• DETAILS ON MATERIALS

Re-use action: reconditioning, stripping, repainting, checking for leaks, fitting, adding legs and fixings, calculating conversion (high temperature > low temperature) for the dimensioning of energy needs.

• COST

302 euros / radiator, including installation.

This is significantly cheaper than buying a new or second-hand cast iron radiator. This is still a competitive price for equipment that is popular for its environmental and aesthetic qualities.







 

INTERIOR JOINERY - OAK CABINETS

• TRACEABILITY

Origin of the lot: existing LOT A building of the Reuilly barracks

Cleaning work: ATD

Reconditioning work: SICRA

The cupboards were removed and stored on site for the duration of the work. A carpentry workshop was set up in the commercial shell to take over the surface treatment and carry out the inventory. The cupboards were installed by the joinery company, which proposed the new guidance system.

Field of use: interior joinery

• DETAILS ON MATERIALS

Re-use action: inventory, hand stripping (sanding) of door surfaces, finishing varnish. Creation of a new wooden frame in MDF and implementation of a new sliding guide system (rollers + rails). Interior fitting of new cupboards.

• COST

Average cost: 137 euros / door or 1270 euros per set of cupboards.







 

INTERIOR FURNITURE - HPL PANELS (High Pressure Laminate)

• TRACEABILITY :

Cleaning work: ATD

Reconditioning work: RONDY FORESTIER

The cupboards were removed and stored on site during the structural work.

The joinery company RONDY FORESTIER then recovered the panels to carry out the cutting (digital milling machine) and assembly in the workshop.

The furniture (stools and high tables) was delivered and assembled on site.

12 stools

8 high worktops 

4 desk tops

18 panels donated to Zero Waste

Area of use: Interior joinery.

• DETAILS ON THE MATERIALS

The panels were used to make furniture for the common areas of the CROUS student residence, stools and high tables.

Addition of a locksmithing batch to make the table bases.

• COST

Cost of a stool: 75 euros per seat

 

EXTERNAL FITTINGS LOT - PAVEMENTS

• TRACEABILITY

Origin of the batch: existing of the barracks of Reuilly
Reconditioning work: removal, cleaning and sawing




 


EXTERNAL FITTINGS LOT - GATE

• TRACEABILITY

Origin of the lot: existing Reuilly barracks
Reconditioning work: dismantling, removal of the metal sheets that were obscuring the gate, sawing to reduce its height and replacement of the missing spikes

 

EXTERNAL FITTINGS LOT - ROOFING SLATES

• TRACEABILITY

Origin of the lot: existing Reuilly barracks
Reconditioning work: the tiles, not very resistant and of poor quality, could no longer fulfil their function as roofing elements. They were therefore removed and crushed to be used as mulch in the green spaces.
