Why renovate a real estate: because it allows us to buy cheaper! The property will cost about 30% cheaper can be, we got home to 188 000 €, a house without works of the same size costs about (in the same town of course) about 230 000 € minimum! But beware the house is cheaper, but it will be necessary to add the cost of the works.
We find on the forums estimates of the order of 100 € per square meter for certain, 500 € per square meter for others ..! The renovation of a house costs between 5000 and 170 000 € depending on what to do, the surface and what you want and can do (so with or without labor).
I have a friend who in 2012 bought a house of 70 square meters, he renovated everything and it cost 25 000 € (partitions and false ceilings, windows and front door, heating, electricity, kitchen, toilet, floor tile). According to several sources on forums, the complete renovation of a barn where everything is to do is close to the 170 000 € (exterior walls, floor tiles, complete roof …).
The renovation only inside a house goes rather near the 30 000 € without masonry, without without renewable energy system, with classical materials (house type 80s lol!).
To estimate the cost of renovating a house, it is necessary to define it from each domain. When you visit the house it is necessary to evaluate its potential, ie after work can it be functional, practical, have a good distribution of parts, practical accessibility to rooms, ample room spaces .. All according to your criteria of course. Then if it is necessary to know what types of work to undertake, evaluate the metrics, and then evaluate the cost of the works. The reality will never be the same as the realization because we always find surprises, we change our mind, we add more … so plan at least 25% more. The different areas of renovation are:
– The roof
– The plumbing (washbasins, WC …)
– Masonry (tiles, floor, exterior walls, fencing …)
– Partitions and false ceilings
– Openers (windows and doors)
– Decoration (not to be neglected, for example to remake the floor of the living room of 25 square meters with tiles costs about 15 € per square meter 375 € of tiles but also requires the glue or the tile of sealing … on Can easily get to 1000 € if you do it yourself, then it takes time, know how … it is not about changing the wallpaper)
– Modification of framing
– Kitchen and bathroom. We find some not too expensive in DIY stores, 2000 € the kitchen is feasible (I do not speak, of course, student type kitchens with 2 pieces of furniture, a sink, 1 microwave and 2 Electric hob, if I have known!).
– Treatment of sewage (septic tanks or connection to mains drainage).
– Thermal and sound insulation
We will give average prices of renovation according to the domain for a house from 70 to 150 square meters approximately, to be able to make an estimate of the price of the renovation of the house you just see (because of course we never have time Nor the courage to encrypt the whole site, it’s about it).
– The roof :
Renovating the framework can vary from 5000 to 30 000 € according to whether to take over or not … I was able to make a quote via a carpenter (because the roof is almost the only area that I do not master correctly ). To change the tiles, to change the battens (wood on which the tiles are laid), to put a tar tar under the tiles for the waterproofing, to make a watertightness of the chimney, to change all the gutters it proposed to me 17 000 €. It is a four-sided roof (composed of 2 triangular surfaces and 2 trapezoidal surfaces, 9 meters long, 9 meters wide, for a maximum of 2.8 meters, the roof is about 80 square meters In a show on france 5 to remake the roof of a house (tiles, battens …)
– Plumbing (washbasins, toilets, water inlet pipes and waste water discharge):
Approximately 3000 € is required for copper or PE pipes with fittings and / or welds, sewage disposal, taps, washbasins, WCs.
– Heating :
If it is a gas central heating of about 8000 € (boiler, radiators, pipes, fittings, welds but without annual maintenance and breakdowns ), if electricity 8000 € (inertial radiators, electric cables, Control thermostat for all radiators). If heating by heat pump about 13000 € , if heating by solar thermal panels about 14 000 € the solar system coupled with a heating network classic to compensate for lack of sun. If you install a heated floor this does not cost more than water heaters. What is not to be forgotten, however,
– Electricity :
There are sockets, switches, cables, switchboards with circuit breakers and differentials, single luminaires, wiring for the oven, washing machine … It takes about 3000 € for the whole house without home automation and the Price can vary greatly if you install electrical appliances type “Legrand” color bidule and modern fixtures stuff tricks … (and without moving or posing to new ERDF arrival). The electrical panel according to the standard NFC15100 about 600 – 1000 € according to the number of departures. We spend at least 1 km of cable !!!
If displacement of the EDF meter , 1500 € for 1 trench meter in the tournament. Then 80 € per meter of additional linear trench.
– Masonry (tiles, floor, exterior walls, window openings …):
It’s hard to say, it all depends on what needs to be done. A ceiling tile (the floor of the floor) about 100 € per square meter , concrete, joist, intervous (blocks of slabs that are placed on concrete joists). Re- tile the ground floor, for example about 6 0 € per meter c arre for cement, sand, scrap … To renovate an exterior wall if it is a stone wall it Must be remade with lime to about 10 € per square meter . In the case of a façade renovation, approximately € 30 per square meter . S ‘ it is necessary to build a cinderblock wall (façade closing …) about 25 € per linear meter for the foundation (reinforcement, cement, sand, gravel) and 20 € per square meter for the wall (cinder block, cement, sand). A portal costs about 800 €
– Partitions and false ceilings:
For ceilings about 15 € per square meter in BA13 with frames and a little insulation; 25 € for BA13 water repellent (bathroom for example). For bulkheads in BA13 honeycomb 9th square meter and 18 € for waterproofing. Rather, it is about 20 € for cellular concrete 10 cm thick, about 12 € for plaster tile and 15 for water repellent . If the partition is a supporting wall ie supports the ceiling the wall can be in cinder block as seen just before 20 € per square meter (no foundation to make). For an interior door , the first price is 27 €,
– Openings (windows and doors).
If the windows have classic dimensions, a single window costs about 100-200 € for a 75 * 75 cm standrard depending on whether they are wooden , PVC , size, classic opening or with double opening option (large and Small opening). A custom window 175 * 175 cm about 1100 €. A PVC window with integral roller shutter costs about 300 € . A roof window (commonly called Velux but it is actually a mark) about 350 € depending on the brand, the options suncuts … A motorized roller shutter costs about 450 € , A PVC rolling shutter manual about 70 €, a shutter double beating in wood about 60 € and PVC about 100 €. A door window costs about 300 €.
Not to be neglected, for example to remake the floor of the living room of 25 square meters with tiles costs about 25 € per square meter 625 € of tiles but also the glue or the tile of sealing … one can easily arrive To 1000 € if you do it yourself, then it takes time, know how … it is not about changing the wallpaper . There it is quite complicated to make a rough estimate because the difference in price between a single more lino painting and a hyper modern tile with decorative paint more false stones to stick can be enormous. Well let’s say the floors are well done, the walls too. All that remains is to make the pure decoration. A lino costs about € 10 per square meter. A beautiful tile (say a very very beautiful) can cost € 50 per square meter . For painting there is a multitude of choices. Let’s take a low average, 12 € per liter for about 10 square meters . A beautiful painting will cost 4 times more expensive, so 50 € per liter for 10 square meters . Include 45 € per square meter for interior stones , 15 € for bathroom wall tiles . A beautiful painting will cost 4 times more expensive, so 50 € per liter for 10 square meters . Include 45 € per square meter for interior stones , 15 € for bathroom wall tiles . A beautiful painting will cost 4 times more expensive, so 50 € per liter for 10 square meters . Include 45 € per square meter for interior stones , 15 € for bathroom wall tiles .
– Modification of framing.
This point is to be taken into account if you have suitable attic space (ie sufficient height to make rooms, an office, a bathroom …) but that the structure of the framework makes that there is Of the beams which prevents the passage at height of man so either one can not make a door or one can not dispose the partitions as one wishes. I have this case at home, 4 beams to be cut with reinforcement to set up. I brought in a craftsman, 3700 € without removing the tiles from the house. I will speak to you about this estimate in the modification section of the framework. We can say about 3000 to 5000 € according to whether to remove some tiles, ease of the building site … But be careful this is not always feasible! It all depends on the type of framework,
– Kitchen and bathroom:
We find some not too expensive in DIY stores, 2000 € the kitchen is feasible (I do not speak, of course, student type kitchens with 2 pieces of furniture, a sink, 1 microwave and 2 Electric hob, if I have known!). But a nice kitchen turns around 8000 – 9000 € .
– Treatment of sewage (septic tanks or connection to mains drainage):
A septic tank costs about 6000 € , a re accord to the whole in the sewer depends on the distance between the house and the ducts of the whole in the sewer, if less than 10 meters about 500 euros , if 80 meters about 2000 €. And it also depends on the subsidies that can be allocated to your municipality.
– Insulation :
Insulation is important to reduce the heating bill. It is necessary to count about 5 to 40 € per square meter for the insulation according to the thickness and the type of insulation. For glass wool in 10 centimeters of thickness about 8 € . We quickly reach the 1500 € of insulation inside.
In exterior insulation one reaches more the 100 € of the square meter with the cladding. A somewhat complicated process, but much more effective.
It may be necessary to replace the means of access to the lower or upper levels. A wooden staircase from 300 € if it is straight, adapted to the standard heights. The average turns rather around 800 € for a staircase a little design. Mine to measure, in qurt turning, 2,84 m high 1800 € without the handrail.
A straight concrete staircase (the simplest) exceeds 1000 €
