The characteristics of a single-storey house

– The most universal single-storey house

Without stairs and benefiting from several access points to the exterior, the single-storey house is suitable for everyone. Retirees favor it for its ease of maintenance in particular, and find it better suited to their old age. As for families, they consider that the single-storey house is simpler to live in, because it requires less supervision of young children.

– The single storey that is easier to maintain

No more cleaning chores on the stairs and difficult moving furniture. Likewise, repainting a shutter no longer requires putting yourself in a dangerous situation. Likewise, the low height of the walls avoids the installation of scaffolding in the event of facade renovation, as explained this article from Figaro.

-A house around the terrace

The single-storey occupies, with an equal surface, a larger space on the ground. But its great asset is its opening onto the garden. The house is often entirely turned towards the outside, making the terrace a real living room. Its shape, often U or L, provides a setting for this primordial space which then becomes the heart of the house.

– Easy resaleFor all these reasons, single-storey houses are more sought after today. They therefore generally leave more quickly than two-story houses. In addition, they often offer the potential for expansion in height since the PLUs often only talk about the floor space coefficient.

The characteristics of the two-storey house

– More suitable for small terrainsns that the house on one level

Despite this enthusiasm, the French chose instead to build two-storey houses. In question, land increasingly small. Occupying less floor space, the two-storey house saves additional square meters, both in the house and in the garden.

– Well-defined living spaces

In a two-storey house, it is easier to separate the sleeping area from the living room. The rooms are thus better protected from the noise of other occupants, who watch television in the living room for example.

Similarly, we can provide the children's area upstairs when the parents grant themselves the bedroom on the ground floor.

– Volume games

Aesthetically, the two-storey house still has its followers. In fact, it offers more play on volume than a single-storey house. Mezzanine above the living room, floor on a single part of the house, the aesthetic possibilities are thus more varied inside and outside. The plan can also more easily adapt to your needs.

Single storey or floor which house is the cheapest?

On an equal surface, a small one-storey house is less expensive than a two-storey house. Indeed, the addition of an intermediate floor, and a staircase, adds nearly 10% to the price of the house. However, on larger surfaces, this ratio is no longer true and even tends to reverse. In question, the price of the frame and the cover which are important items in the construction of a detached house. In a single-storey house, the surface of the roof is in fact twice as large as that of a two-storey house of the same surface.

Beyond a certain surface, the two-storey house is comparatively cheaper to build.

The more economical two-storey house in the long term

– Less energy for heating

Another advantage of the two-storey house is its compactness. There are proportionally fewer wasting surfaces, such as the roof or exterior walls. As a result, multi-storey houses consume less energy for heating for equal surfaces than single-storey houses. In the long term, energy savings are important!

– Savings on domestic hot water

On the same principle, the water features are often placed one above the other in a two-storey house. If the whole is close to the production of domestic hot water (water heater), there again these are still energy savings. Indeed, in a single-storey house, the various bathrooms and the kitchen are often far from each other. The water network is therefore larger. This is detrimental to the comfort of use since the hot water takes longer to travel to the point of use. Heat losses are also greater.
