Floor space beneath a ceiling lower than 1.80 metres is excluded from France’s statutory definition of habitable area. So are balconies and terraces. Those exclusions, set out in Article R156-1 of the Construction and Housing Code, matter rather a lot when an Alpine apartment comes with a steep roof and a generous outdoor deck.
The more attractive the drawing, the easier it is to skim past what it measures. Pale timber, a strategically placed sofa and a mountain-facing terrace can make almost any plan look agreeable. Before reserving a new-build ski property, put the furniture illustration aside and establish how the apartment will actually work with coats, luggage, sleeping children and people trying to eat breakfast. A good plan should survive that exercise.
Keep the indoor and outdoor numbers separate
Start with the surface schedule, usually a small table beside the drawing. Ask which figure is the surface habitable, what each other total contains, and whether the room measurements reconcile with it. Under the statutory definition, walls, partitions, stairs and certain other occupied areas are deducted; garages, cellars and several types of ancillary space are excluded. The headline number needs a name, not an approving nod.
Consider a purely illustrative apartment with 62 m² of habitable interior and a 14 m² terrace. The two areas may both be valuable, but adding them produces 76 m² of unlike space. It does not create a larger living room. Keep separate columns for interior, exterior and storage when comparing properties. These figures illustrate the method; they describe no current DOMOSNO listing.
That discipline also prevents misleading price comparisons. Do not divide one asking price by habitable area and another by a combined indoor-and-outdoor total. Check whether parking, storage and any furniture package are included in each price before drawing conclusions from a per-square-metre calculation.
Resale documents may use a different measure. ANIL’s explanation of the Carrez measurement describes the private-lot area required for qualifying condominium sales. Do not assume every area label in a resale advertisement means the same thing as the habitable area in a new-build schedule. Ask the agent or notaire to identify the measure used and resolve discrepancies.
Give the furniture an honest audition
Request a dimensioned plan with a legible scale, then check the actual furniture you intend to buy. A bed symbol can be remarkably diplomatic about a small room. If your chosen mattress is 160 cm wide, use that measurement, add the bed frame, and check the space left for walking, opening cupboards and reaching the window. This is a furnishing test, not a statement of regulatory minimum dimensions.
At a printed scale of 1:50, a metre in the room occupies two centimetres on paper. That only helps if the file has been printed at the intended size. “Fit to page” can make a ruler confidently wrong. Use the written dimensions first, and ask for missing measurements instead of estimating from a screenshot.
Next, draw the sofa bed fully open. Can somebody reach the bathroom without climbing over it? Can the balcony door still open? Does breakfast require everyone to fold away their bedding? A sofa bed may be a perfectly sensible occasional option; making it central to every family stay is a different design decision.
Run the same test at the dining table. Put the expected occupants in chairs and allow for people getting up, not merely sitting still. Check the dishwasher and oven doors against nearby cupboards. The test is deliberately ordinary. You are buying a place to stay, and ordinary movements are what fill most of a holiday.
A cabin bedroom needs its own description
Alpine floor plans often distinguish conventional bedrooms from a cabine or coin montagne. Keep that distinction visible when counting sleeping rooms. If a property has two conventional bedrooms and a separate bunk bedroom, record the bunk bedroom in the overall bedroom count while clearly identifying its type. Do not turn an open sleeping recess into an enclosed bedroom by changing the English label.
Ask for its dimensions, ceiling height, door arrangement, window provision and ventilation details. Check where the ladder will sit, where bags will go and how the space connects to the main room. A compact bunk bedroom can be useful for your household without being equivalent to a conventional double bedroom.
Then separate beds from practical capacity. A drawing that accommodates a particular number of sleepers says little about simultaneous showers, coats drying or dinner seating. For a rental purchase, give the proposed plan to the local manager and ask how they would describe and operate it. Obtain any necessary compliance advice separately; a sales label is not proof of suitability for every intended use.
For your own holidays, write down who sleeps where. Teenagers, grandparents and occasional friends rarely have identical requirements. A plan that works beautifully for your family need not advertise the largest possible headcount.
Read the balcony in depth
A balcony’s total area is only the beginning. Ask for its clear depth, position of doors, any pillars and the footprint of fixed equipment. A long, shallow strip and a deeper rectangle can have similar areas but very different uses. Place your intended table on the plan, add chairs, and leave room to move around them.
Study what is above and beside it. An overhead balcony may provide welcome shelter; it may also affect daylight inside. A solid balustrade offers a different seated view from an open railing. Ask for elevations and a section drawing where the floor plan leaves these relationships unclear.
For a ground-floor terrace, establish the boundary, access route and relationship with shared paths. Ask the notaire to confirm the legal nature of the outdoor space and the relevant condominium provisions. A private-looking patch on a coloured plan does not explain ownership or use rights.
Do not accept a summer furniture illustration as evidence of year-round usability. Ask about exposure, drainage and the building’s arrangements for snow clearance. You need project-specific answers. A sheltered place for lunch and a useful winter access route are both worthwhile, but they ask different things of the same piece of space.
Follow the boots from the front door
Trace the route from arrival to the apartment, including parking if you need it. Locate the lift, stairs, entrance lobby and ski storage on the building plans. An apartment plan alone cannot show whether returning with children and equipment involves an awkward detour through several doors.
Find out exactly what “ski locker” includes. Request its internal dimensions, the locking arrangement, any power or drying provision, and confirmation of what belongs to the apartment. Do not assume a heated boot rack from a photograph of the residence’s general facilities. Check where helmets and poles will fit as well as skis.
Inside the apartment, decide where wet coats stop and clean floors begin. A small entrance with sensible storage may serve you better than a more dramatic opening into the living room. Locate the washing machine, cleaning cupboard, suitcase storage and space for linen. These are questions for the equipment specification as much as the plan.
If you will let the property, identify storage you can lock for your own belongings without removing the cupboards guests need. Ask the manager about linen changeovers and access. No rental-income forecast is required to see the benefit of solving these details before cabinetry is ordered.
The north arrow cannot tell the whole story
Orientation deserves attention, but it does not describe neighbouring buildings, projecting roofs or mountain shade. Request a site plan and elevations alongside the apartment layout. Establish which rooms receive direct light, which windows actually open, and what is immediately outside them.
ADEME’s housing-design advice explains why orientation and solar protection belong in the same conversation. Winter solar gains can be useful, while summer comfort depends on controlling unwanted heat; west-facing openings can be harder to shade. The guidance concerns building design generally, rather than certifying any particular Alpine development.
For the apartment you are considering, ask what external shading is included and how occupants operate it. Look for a practical route for ventilation, subject to the building’s design and safety requirements. A corner apartment may offer different possibilities from one with windows on a single elevation, but the plan needs checking rather than awarding automatic points.
Also locate the bedroom walls relative to circulation spaces and equipment rooms. A plan can identify questions about noise; it cannot demonstrate acoustic performance. Ask the developer for the relevant specification. Buyers visiting from abroad can cover these points in a focused video call with marked-up drawings before travelling.
Finish with a dated set of documents
Keep the latest plan, surface schedule and specification together, recording their dates and revision references. Service Public’s reservation-contract guidance lists habitable area, room information, ancillary spaces, materials and the property’s position in the building among the required information. Use those documents to pin down the actual unit, not simply the overall development.
The distinction becomes firmer at the final sale stage. Service Public’s guide to the VEFA sale deed identifies the dimensioned plan and equipment notice among its annexes. Ask your notaire which documents will form part of your agreement and how differences between versions should be resolved.
Put requested changes in writing and ask the developer to confirm feasibility, cost, deadline and the revised drawing. Moving a cupboard and relocating plumbing are different propositions. Never assume a verbal suggestion has become part of the agreed specification.
Finally, revisit the plan with your original priorities beside it. Does it still offer the rooms, storage, outdoor use and everyday comfort you wanted? This is where a shortlist of new-build ski properties becomes a comparison of homes rather than illustrations. The most useful square metres are the ones that support the way you intend to live.
If you have an Alpine new-build shortlist, ask DOMOSNO to help you compare the plans and obtain the missing dimensions or specifications before you make your choice.
