Who can make me a house plan?
One of the first steps in a construction project, and not the least, is to develop the house plans. But how do you know who can draw them ? What are the advantages and disadvantages of each option ?
Draw the plans of his house yourself
When you want to build your house, it may be tempting to get started on the plans yourself. To do this, you must start by determining a certain number of characteristics: the total area, the number of rooms, their layout, their volume, the presence of an open or traditional kitchen, and the shape that the house as a whole will take. . Once you have listed your requirements, you should preferably have dedicated software to develop plans that can be exploited and that will include as much detail as possible.
The advantage of drawing the plans yourself is that it costs you nothing and that you have absolutely control over everything. On the other hand, it is imperative to have technical skills, because the slightest error can compromise the entire construction and generate an additional cost on the site. In addition, there are many more things to consider than is generally believed. You have to take into account the nature of the terrain, its orientation, the neighborhood, town planning rules, thermal regulations, etc. In short, drawing plans is not improvised, especially since it will have an impact on the smooth running of the work and the comfort of your future at home.
Entrust the plans to a manufacturer within the framework of the CCMI
You can decide to entrust the plans of your house to a manufacturer within the framework of a CCMI (individual house construction contract). This is the most secure and simplest solution, since the manufacturer takes care of everything, from administrative formalities to construction. You will be able to choose plans from a catalog and you have solid guarantees, since the realization of the plans leads to the construction which itself brings you the guarantee of respect of deadlines, firm and final prices, of damage-work insurance , ten-year warranty, etc.
The advantage of going through a manufacturer for the development of plans is that he knows them by heart since he is used to building houses on the basis of the plans he offers you, this guarantees the good progress of the site and respect for the chosen plans. However, you must choose standardized plans, they will not be personalized and you will have little leeway to obtain modifications.
The 100% personalized plans drawn by an architect
By calling on an architect to draw up the plans for your house, you can afford anything. You will simply paint a portrait of your ideal home with as many indications as possible, and the architect will take care of drawing the house of your dreams, the one that corresponds to you in all respects. So it allows you to get a house that looks like you and looks like no other. Once the plans have been drawn, you can choose whether or not to entrust the construction to the architect, but he can only intervene to draw the plans.
The architect applies fees representing approximately 10 to 12% of the total cost for a full mission, and the plans will be paid if he only intervenes in this context. In addition, note that the architect does not take care of the administrative formalities, so it will be up to you to take care of them. Finally, note that, whatever the number of missions entrusted to the architect, these are noted in a master’s contract, which is compulsory but which provides fewer protections and guarantees than a CCMI
Plans developed by a project manager or a design office
It is possible to entrust the development of your home plans to a prime contractor or a design office. You then have the same advantages as with an architect insofar as you can obtain personalized plans, whether it be the shape of the house, the layout of the parts, materials and equipment. But this time, the professional places particular emphasis on the technical aspect, and he can also take care of the administrative procedures if you subsequently entrust him with the construction of your house.
The fees of a project manager or a design office generally amount to between 7 and 10% of the total cost of the work if it occurs in all phases of the project, and the plans are chargeable if you only call on him for this mission.
