The price of a traditional house construction

The estimation of a house is carried out in several stages, differentiating the construction methods, the type of architecture and taking into account the new regulations. Estimating the cost of renovating a house may take up a large part of these criteria.

The budget of a traditional house is calculated after defining the type of construction material, the construction standard, the level of completion of the works, that is to say house outside water and outside air or turnkey but above all the exact dimension and the form: the price of a house on one level is different from that of a house on a floor. Different questions will arise to determine the amount of construction: should an architect, a design office or a manufacturer be called upon ? Should we favor simple volumetrics ? What form best adapts to the specificities of my land ? What materials to comply with the new thermal regulations or even what services to arrange the interior ?

  • A rectangular concrete house, to the standards in force and delivered turnkey ready to be decorated, returns on average to 1,500 euros per m², insisting, however, that floor houses are a little more expensive than single-foot houses since the weight to be borne requires the creation of very resistant foundations. An additional cost of 100 euros to 200 euros is therefore to be expected.
  • The amount of a turnkey brick construction ready to decorate is from € 1,000 to € 1,800 per m². If this same construction is delivered out of air and out of water with the completed structural work, the price ranges from € 600 to € 800 per m². If the brick construction is on the floor, the budget is from 15,000 € to 30,000 € higher depending on the area of the place and the professional chosen.

The price of a wood house construction

The estimation of the cost of a house construction work is facilitated if the construction materials are known in advance. Assessing the cost of a wooden house consists in listing the various factors that will influence the final cost. The area, the type of construction, the energy performance, the assembly technique chosen and the level of completion of the works proposed: house out of air and out of water, in self-construction or turnkey, will determine the price of the construction of a wooden house.

Professionals insist on various points and ask their customers to reflect on the preferred wood essence (European or exotic wood) on the mounting technique (wood frame or planks) and on the interior layout, specifying the type of insulation, coating materials and the heating system.

  • The price of a house in a self-construction kit begins at 350 € per square meter.
  • A hand-turnkey classic wooden house costs between € 700 and € 3,000 per square meter, assuming an average range of € 700 to € 1,200 per square meter.

How to estimate the price of an ecological house construction ?

The construction of an ecological house is based on standards and regulations, at least on RT2012, thermal regulations providing for a reduction in energy consumption and greenhouse gas emissions. This legislation applies to any building permit issued since January 1, 2013.

The estimation of the cost of building an ecological house is based on the quality of the materials used, the technologies adopted and the expected performance. Passive or positive houses are much more demanding than traditional houses respecting only RT2012.

  • The price of the gas connection of less than 30 meters begins at 335 € but can reach a price of 1,012 € TTC
  • The additional cost for a connection beyond 30 meters is € 100 HT per meter dug.
  • The water connection returns to € 1,500 for a length of less than € 10 m and € 50 per additional linear meter.
