Dimitri Debien has always had a clear idea of the house of his dreams: a building that he would build himself for the sake of economy, with large volumes and an imposing tower. A beautiful dream come true!
Since a young age, our reader has always wanted to build his house, but not just any: "I dreamed of having a house with a specific shape and a tower." True thread, Dimitri Debien leads his project with the help of Elodie, his companion, his family and friends. The plans of this house were realized and targeted by an architect: "We told him what we wanted, especially large rooms, our stay being more than 50 m2." The land acquired and the permit granted, our reader undertakes the work. First, the implementation: "Not simple because of the intricate architecture of the house."
First important and delicate step, the layout of the establishment of the house. Theodolite and building plans in hand, this task requires some skill, especially for the diagonal line (thank you Pythagoras!).
Apart from the heating system, Dimitri Debien realized everything: "For 17 months, I spent all my evenings, weekends and holidays".
For the earthworks and the VRD (road and various network), our reader calls on a digger. A pocket of clay imposes the realization of a small slab to reinforce the future soles of the foundations.
The construction starts with the cellar. On the insoles made beforehand are set up, side by side, two rows of concrete blocks full of 20 cm thick: "I planned two parallel rows to prepare a good seat to the Monomur bricks of the structure that are 37.5 cm thick."
Given the thickness of the walls, the soles, made with a ready-mixed concrete dosed at 300 kg / m3 of cement, have a depth of 70 cm for a width of 50 cm.
Last step for the cellar, whose external walls were backfilled: the realization of the floor and the preparation of the concrete belt with hollow blocks and scrap. The floor is executed with a conventional girder slab system, completed with a compression slab.
A Canadian well, consisting of PVC pipes and fittings, buried at 2 m, is planned to ventilate the cellar and ensure a constant temperature.
The slab is made on the ground. As for the cellar and for the same stability requirement, our reader has set up, before pouring, two rows of parallel blocks around the entire perimeter of the house. On the ground, polystyrene panels 4 cm thick, placed before the polyane, provide a thermal break.
This is the most delicate step: laying the first row of Monomur bricks. This perfectly level - each brick is checked - is made on a bed of mortar approximately 2.5 cm thick. To ensure the perfect bonding of the bricks, the mortar is powdered with a brick resin.
After the first row, "It's a Lego game!". The following blocks are bonded using the thin-walled masonry technique. Here, no mortar but a glue applied with a tool specific to the width of the bricks, to a thickness of about 3 mm. The bricks are simply cut with a saw.
And here is the tower!
The first floor, exterior wall and wall of the roof, is now finished. It's time to set up the floors. Depending on their location in the house, our reader uses two techniques: floor girder slab or wood joist.
Due to the large span, the upper floor of the main room has a glued-laminated beam 8.70 m long (1. 16.5 cm, h 50 cm). The joists rest on the brick walls and are secured to the beam using metal connectors type hooves. Only the laminated beam will remain visible, the joists will be hidden by the false ceiling plasterboard.
Although the frame is very aesthetic, the couple did not want to leave it completely apparent: "I kept some visible pieces like some rafters or feet of farm... "
Masonry is now complete. There remains the frame and the cover. A moment of reflection during which we attack the outline of the frame according to plans. Then, it is the cutting of the pieces.
The house is transformed into a workshop: the blank assembly of the frame of the tower makes it possible to verify that all the assemblies fit perfectly.
When the work is ready, the pieces are numbered, then the frame is dismantled to be transported piece by piece to the second level of the tower.
The roofing work begins with the installation of the rain cover, maintained by a counter-lathing. Then, it is the laying of the battens.
The hips are made using traditional methods using a mixture of white lime, white cement and sand.
Traditional carpentry and roof
For the frame, no industrial farmhouse but an assembly designed and realized according to traditional methods: "I obviously cut it on the spot by realizing a sketch and all the assemblies are with tenons and mortises or molded". His editing required a good dose of elbow grease: "After preparation in the future open-air dining room, we dismantled it and then mounted one by one all the elements up to the second floor".
As for the cover, it too was made according to the aesthetic criteria of the Indre: "I wanted a cover in small tiles, it is very aesthetic but it requires a lot of handling: there are 55 tiles per square meter" says Dimitri Debien. The result is there: with its tower, its original architecture, its quality masonry covered with a monolayer coating your stone, the house reveals its traditional character, well anchored in the territory.
Small, aged tiles have been chosen. At the same time as their installation, the skylights are built.
Alternatives to monomur brick
The house of our reader could have been constructed of cellular concrete or concrete blocks made of aggregates of pumice. In these systems, as with the brick Monomur, the wall is both carrier and insulation, without addition of inner or outer lining. In line with the thermal regulations, including the last much more severe (RT 2012), they meet three points now essential to any construction: insulation, inertia and airtightness. It is at the same time the insulating properties of the blocks and the limitation, or even the suppression, of the thermal bridges at the sensitive points of the masonry (intermediate floor, link external wall / slit, angles...) which give them these good thermal performances.
