GLOSSARY:
* SHONRT (Net floor area in the sense of the Thermal Regulations of a building or part of a building used as a
house, single housing and multiple housing) :
Total floor area of each level of the building, after deduction of room surfaces without heating equipment
SHONRT (for buildings other than dwellings) is the result of multiplying the usable floor area of the building by a
factor depending on the use of the building
SHONRT = Fact .SURT (usable floor area in the sense of the Thermal Regulations)
The multiplying factor depends on the use of the building :
-Offices, primary schools: 1,1
- Secondary schools, early childhood centres, Homes for young workers, university housing : 1,2
*SHON (surface hors œuvre nette): Net Floor Area: floor area of the construction,
SHON is a measure of floor area for building construction projects. It allowed:
- to check that the density of buildings complies with the building to plot ratio applicable to the property.
- to form the basis for calculating taxes related to building construction (TLE: taxe locale d’équipement, TDENS: taxe
départementale des Espaces Naturels Sensibles, CAUE: Conseil d’architecture, d’Urbanisme et d’Environnement, …)
La SHON se calculait en soustrayant à la surface hors œuvre brute (SHOB) les surfaces suivantes1 :
The net floor area was calculated by subtracting from the gross floor area (GFA) the following surfaces:
Attic and basement space with a ceiling height less than 1.80 m;
Surfaces of flat roofs, balconies and unclosed portions located on the ground floor,
Areas currently used as technical facilities located in the basement and attic;
Areas currently used as a cellar in the basement provided that there is no opening to the outside other than those
provided for ventilation;
Building areas or part of building areas used for parking vehicles (garage);
Building areas used for housing crops, animals or farm equipment;
Area equal to 5% of the gross floor area used for housing (standard deduction for insulation of the premises), after
applying the above deductions for housing;
Specific deduction for residential building retrofit operations within 5 m2 per dwelling unit for work aimed at
improving hygiene ;
Deduction of a fixed area of 5 m2 per housing complying with the rules relating to inner accessibility for disabled
persons, provided for either in Articles R. 111-18-2, R. 111-18-6 or Articles R. 111-18-8 and R. 111-18-9 of the Code
of Construction and Housing.

12. 11
There is some case law on the concept of areas awaiting conversion or not particularly for cellars. In this regard, a
judgment of 18 May 2004 issued by the Administrative Court of Appeal of Paris ruled. This judgment motivated a
ministerial response as well as a response published in the official bulletin of urban planning law in May 2005. These
responses clearly indicate that the criteria for consistency and allocation of premises must not be confused.
The Net Floor Area must be less or equal to the land area multiplied by the building to plot ratio.
*SHAB (living area) :
The living area of a dwelling is the built floor area, after deduction of surfaces occupied by walls, partitions, stairs
and stairwells, ducts, doorways and windows; the living space is the total living areas thus defined multiplied by
ceiling heights.
Account is not taken of the unconverted area of the attic, cellars, basements, sheds, garages, terraces, loggias,
balconies, outdoor dryers, verandas, glazed volumes provided for in Article R. 111-10, common areas and other
outbuildings, or parts of premises lower than 1.80 m high.
*SDP (Surface de plancher): floor area:
The floor area of the building is defined as:
"[...] the sum of the surfaces of floors for each level closed and covered, calculated from the bare interior walls
minus:
Surfaces corresponding to the thickness of the walls surrounding the doorways and windows overlooking the
outside;
Voids and hoppers relating to stairs and elevators ;
Floor surfaces of a ceiling height less than or equal to 1.80 meter;
Floor areas developed for parking motor vehicles or not, including access ramps and manoeuvring areas ;
Floor surfaces of attics with insufficient headroom for living or for professional, craft, industrial or commercial
activities;
Floor surfaces of technical facilities necessary for the functioning of a group of buildings or a building other than a
house within the meaning of Article L. 231-1 of the Code of Construction and Housing , including waste storage
premises;
Floor surfaces of cellars or storerooms, neighbouring dwellings, when these facilities are served only by a common
part;
Covering an area equal to 10% of floor surfaces used for residential purposes possibly resulting from the application
of the preceding paragraphs, when the dwellings are serviced by internal communal space. "
- Article R. 112-2 of the Town Planning Code, as amended in Decree of 29 December 2011.1
We can see from reading this regulatory definition that some deductions only exist in buildings with multiple
dwelling units or buildings which are not being allocated to housing (technical rooms, basements and cellars with a
ceiling height greater than1.80 m, 10% of the areas served only by common parts).
The accuracy of the terms of the decree should make the calculation of the floor area less objectionable than the old
SHON.
Unlike SHON, the notion of floor area is not used for the calculation of planning taxation. Indeed, the development
fee, which also replaces the local equipment fee, as from March 1, 2012, provides its own calculation of surfaces,
also calculated from the bare interior walls, but with fewer deductions than the SDP.
