Creating the ideal home is not about reproducing a magazine photo. It’s about starting from your daily life, from your actual habits, to design an interior that works as much as it pleases you. The project begins long before choosing coverings or windows: it starts with a careful reading of your land, your regulatory constraints, and how you occupy each room.
Room Orientation and RE2020: The Plan That Conditions Everything Else
You may have already noticed that a room facing north stays cool even in summer, while a south-facing living room can become stifling as early as June? This simple observation now guides the design of new homes, and the environmental regulation RE2020 has made it even more structuring.

Since its implementation on January 1, 2022, RE2020 is not limited to the choice of heating or insulation. It pushes designers to rethink the distribution of rooms based on solar orientation. Specifically, living spaces are placed to the south and buffer spaces to the north (garage, pantry, laundry room). Solar protections, such as architectural overhangs or sunshades, become elements of the plan, not decorative additions.
This logic also modifies the size and position of windows. Large openings to the south capture light and heat in winter. To the north and west, more modest windows limit heat loss. Therefore, before choosing a type of sliding door, the placement of the house on the land must be validated.

Adaptable Housing: Anticipating Aging from the Plans
Most articles on the ideal home talk about planning for an additional children’s room. Few address a crucial topic: adapting housing for aging from the design stage.
The National Housing Agency (Anah) highlights the progress of adaptation works and now promotes “adaptable” housing designed from the outset, not just at the end of the residential journey. The Ministry of Ecological Transition relays this logic of adaptable housing in its communications on housing, influencing the practices of individual home builders.
Why this choice? Because a hallway that is too narrow, a raised shower threshold, or a staircase without an alternative on the ground floor costs much more to correct after construction than to integrate into the initial plan. The principles are simple:
- Plan for doors at least 90 cm wide to allow the passage of a wheelchair or walker, without later renovations
- Install a walk-in shower rather than a bathtub in the ground floor bathroom, even if you are thirty years old today
- Place a bedroom and a full bathroom on the ground floor, so you can live on one level when the time comes
- Size the staircase well enough to add a stairlift without modifying the structure
These choices cost almost nothing at the planning stage. They avoid heavy renovations twenty years later.
Home Budget: Balancing Between Walls, Insulation, and Finishes
The budget for a home is divided between the structural work (walls, framework, foundations), insulation, technical equipment, and finishes. The classic temptation is to cut back on insulation to fund nicer finishes. This is a costly mistake in the long run.
Insulation and windows condition daily comfort and the energy bill throughout the building’s lifespan. A floor covering can be changed. Therefore, prioritize the thermal envelope and joinery during construction, even if it means installing temporary finishes that you will replace later.
Another often underestimated item: outdoor work. Earthworks, connections, fences, and landscaping can represent a significant portion of the total budget. If your land is sloped or clayey, these costs can rise quickly. It’s better to estimate them before finalizing the interior plan.
Wall and Interior Finishes: What Can Wait
Wall coverings (paint, decorative plaster, wallpaper) and floor coverings (parquet, tiles) are among the easiest items to modify after moving in. If the budget is tight, a quality white paint is enough to start. You will personalize the interior gradually, without compromising the technical performance of the house.
Interior Layout: Circulation and Quiet Zones
A good house plan reads like a journey. From the entrance, you should be able to access the kitchen, living room, and bedrooms without crossing a living area each time. Hallways have a bad reputation because they “waste” space, but a well-placed hallway protects the privacy of the bedrooms and reduces noise.
Consider separating the day zone (kitchen, living room, dining room) from the night zone (bedrooms, bathroom). This distinction seems basic, but many open plans sacrifice it for a “large volume” effect that becomes tiring daily. A poorly zoned open space generates noise and reduces privacy.
The kitchen deserves special attention. Located near the entrance and garage, it facilitates the storage of groceries. Facing the garden or terrace, it becomes a pleasant living space. These two objectives are not always compatible: it’s a trade-off to make based on your land and lifestyle.
Technical Rooms: Don’t Forget Them
Utility room, pantry, technical room for the heat pump or hot water tank: these rooms do not appear in decoration magazines. However, forgetting the technical room at the planning stage leads to costly fixes. Plan for a ventilated, accessible space that is large enough to accommodate equipment without overcrowding.
The ideal home project is played out in these concrete trade-offs, not in the accumulation of trends. A well-oriented plan, a home designed to evolve with you, and a budget wisely divided between structure and finishes: these are the three pillars on which every detail decision can then rely.
