And to perfect your project, here are some tips that could be useful to you…


1. Use trusted professionals and home builders 

Who can carry out the construction plans for your house for and with you? Only three trades are authorized: Architects, project managers and builders of new houses. 

choose your home builder for your construction plans

At Maisons SIC, we have been supporting future owners of new homes from A to Z for nearly 50 years : we work together on a solution around the land, a financing solution but also a solution around the house itself, by determining the architecture best suited to your desires, your needs, your lifestyle but also the feasibility in strict compliance with the town planning rules in force.

It is not impossible to make the plans for your detached house alone. But, apart from the specific know-how that this requires, you should know that depending on the net surface area (SHON) of your future construction, an architect may be required. Instead, opt for a professional. 


2. Choose your house style to properly design the building plans

Even before design your house plans, you can take an interest in the different construction styles that exist to define the one that “speaks” to you the most or that best suits your lifestyle. Do not hesitate to consult our article on the 8 types of individual houses to discover before choosing which one to build

You can then decide for a contemporary or traditional house, two-storey or single-storey, flat roof terrace or tiled roof, ecological, semi-detached or wooden frame. 


3. Realize the construction plans of your house according to your family needs and your daily life

One of the first things to take into account when you are going to choose the style of your detached house and therefore the style of house construction plans to achieve, is your needs, your desired lifestyle. A family with a young child will not have the same needs for m2 and circulation space as a family with 3 children, a childless couple or retired people. Your way of life will determine the number of rooms, the opening, the presence or not of a floor and a staircase, the nature of the rooms (need an office? a garage? games? how many bathrooms? a day area clearly separated from the sleeping area?). 


4. Define the budget before thinking about the construction plans of your house

When you embark on the realization of the construction plans of your new house, you want to afford these spaces which are not always possible in an old house. But it is very important to always take into account the financial variable. 

the budget for his new house

Your partner in building your home can help you define your budget. Depending on your maximum financing capacity, it will help you determine the maximum living space, the rooms necessary for your lifestyle, the architectural model (single-storey, two-story). Then, when the “necessary” is in place and, if it fits into the budget, you can think about secondary arrangements for you (this could be the addition of a garage, a basement, a veranda) . 


5. Take into account the land chosen to better think about the construction plans of your new house

The land is also one of the key elements to take into account when you start thinking about your house construction plans. Whether you have already found it or your builder has found it for you, your house will necessarily have to adapt to its environment. It will therefore be necessary to take into account, in your plans, the area and size of the land, but also the orientation and the opposite or the configuration of the said land and the composition of the basement.

With regard to the vis-à-vis for example, it is necessary to inquire about the national and local planning rules (PLU) define minimum distances to be respected between two constructions, to avoid creating openings which one will then have to condemn, for example. 

You can also consult the geological surveys of your municipality or have a soil study plan drawn up to find out if your land is rather clayey, rocky, wet or even marshy, homogeneous or heterogeneous (backfill), and what is the depth of the water table. groundwater.

And if your land is sloping, your plans will necessarily have to take into account the difference in height, especially if it is significant. In any case, it is your plans that will adapt to the terrain and not the other way around. 


6. Reflect your house plan in 3D (or not) with plants and orientation

Your house plans will also have to adapt to the desired orientation to bring in as much natural light as possible into your home. By planning the layout of your rooms according to the orientation of the openings, you will be able to considerably reduce your energy savings (and therefore your environmental impact) and, above all, you will optimize your living comfort with omnipresent outdoor light. 

In the North, do not hesitate to put the garage, the cellar, the laundry room, the bathrooms, the toilets, the entrance... All the rooms which do not need to take advantage of the sunshine. 

The family living rooms such as the dining room, the living room or the games rooms will be well located to the south, like the bedrooms, if you like natural light. 

Otherwise, one can put the rooms in the east or in the west, like the kitchen. 


7. Think about the circulation between rooms, on the construction plans of your house

Circulations generally appear by themselves when the layout of all the rooms has been decided. But it is still important to work them well. It should be noted that internal circulation should not be less than 0.90 m. If you have to manage a stroller, a toddler or a person with reduced mobility, these circulation spaces must be enlarged as much as possible. 

How to finance your new house?

To reflect on the plan of your house these circulation spaces you can define the rooms most frequented by the members of your family, to better connect them to each other; and, on the contrary, define the spaces that must be more isolated (such as, for example, a bathroom for someone who starts working earlier than the rest of the family).


8. Openings: a crucial point in the construction plans of your house 

To think well about the plans of your house, you have to think about all its openings. When we have defined the rules vis-à-vis and in relation to the neighborhood, for the prior declarations to the town hall, we can think about the place of the openings. The ideal is to place as much as possible in the South to take advantage of the natural light and the heat of the sun. Reduce the openings to the north as this could cause heat loss. 

As for the size of the openings, it is up to you to choose according to the desired model, while keeping in mind that the RT2012 now imposes for new constructions a minimum of glazed surface of 1m² for 6m² of living space.


9. House plans 2 bedrooms, 3 bedrooms, 4 bedrooms, single storey, floor: think evolution and modularity

The plans you are going to make can also take into account the perspective of a resale or life changes. If you have the budget for it, think modularity and evolution of surfaces. So don't hesitate to think about possible extensions and leave the possibility of adding an extension somewhere (depending on the terrain, for example) or a floor, a garage...


10. Integrate the facade composition into the construction plan of your house

We sometimes tend to want to think about the layout of each room but not to take the facades into account. But a house can also be lived outside, especially in summer. So also think about your plans for a house that is pleasant to look at: balanced proportions, a well-thought-out ratio of solids (walls) and voids (openings), aesthetic window positions...
