To build your home, you need a plan, but also a budget. These two elements require the intervention of experts to help you complete your project. Here are a few people to ask about designing your home and estimating the cost of making it!
Refer to a single-family home builder
The single-family home builder takes care of all the shopping for the house. From design to getting the key to the door, he does it all, and you pay.
With the latter, you will be bound by two types of contracts with very good guarantees. This is the CCMI or Contract for the Construction of a Single-Family Home and the VEFA or Sale in the State of Future Completion. VEFA concerns cases of sale of land, in addition to construction. The guarantees given to you by these two contracts are:
- meeting deadlines;
- the firm and final price;
- damage insurance for works;
- the ten-year guarantee.
Entrusted, the design and estimation to these professionals amount to making a choice among the offers that are offered to you. Select the plans and materials. The estimate will therefore follow the standard price. For personalization, be prepared to pay more.
Contact a project manager or a design office
The project manager or the design office does a lot more in the realization of your project. They focus their efforts much more on the technique than on the plan itself. The master-builder intervenes throughout the construction process of the house. It can be limited just for estimation and construction or to do all the work.
A project management contract will give the limits of intervention of the master as well as his fees. The fees range from 7 to 10% of the total estimated price for all the work. Design offices and contractors must have compulsory insurance. Without it, don’t trust them. Also, always check their old projects.
Choose an architect for the design
The architect will make a personalized plan for you. It helps you to design with the materials of your choice and according to your imagination. Your house will be different from that of your neighbors, except of course, in terms of urbanization standards. The latter will be paid according to the total expenditure made for the construction. It will therefore take 10 to 12% excluding taxes of the construction price.
The architect’s mission can be defined by you. Either it does a full job from concept to completion, or it is limited to design only. In the latter case, all administrative procedures are your responsibility.
A project management contract binds you to the architect if you choose him to do the entire job. For a 170 m² room excluding the net work, you must entrust the work to an architect. On the other hand, architecture possesses the moral property of its work. Thus, he can oppose any subsequent modification of the house.
In general, the design of your home and its cost can be left to a contractor, an architect or a single-family home builder.
