To make a tailor-made house, it is possible to contact various professionals. Depending on your needs, project manager, architect or custom home builder will be able to satisfy your desires. Each solution has advantages and disadvantages, details below.
Build a custom house by a project manager
The project manager draws up the plans for the house, while ensuring the smooth running of the work. He guides the client in choosing the craftsmen who will do the various jobs. Typically, it offers standardized plans, but modifiable to a certain extent. Construction prices are therefore lower than with an architect.
However, this solution requires vigilance, as the project manager cannot be held responsible for potential construction errors. Indeed, the project management contract is not regulated; this professional therefore only has an obligation of means.
Build a custom house by an architect
A liberal professional, the architect is the ideal person to build a 100% tailor-made house. His state diploma from a school of architecture attests to the quality of the house’s design. The plans are tailor-made, fully corresponding to the customer’s wishes. This is nevertheless felt in the price, which is higher than with a project manager or a home builder.
In addition, the architect is a professional subject to the ethics of the national order of architects. This is very reassuring for the customer.
Build a custom house by a home builder
The house builder is a single point of contact, with which the client signs a contract for the construction of a single-family house (CCMI). This is the most economical choice, as standardization of models reduces costs. The models are generally modifiable, in order to adhere to the requirements of the customers.
Regulated, the CCMI protects the customer by guaranteeing, for example, the cost of construction (protection against additional costs). It also includes a delivery guarantee at the time agreed in the contract.
Service and type of professional
Depending on the type of service and professional chosen, the price of your house can go from one extreme to the other. For example, it will be more important with an architect for 100% tailor-made than with a builder of individual houses with plains of existing houses.
Architecture and volume of the house
The price of your house will also depend on its architecture (traditional or contemporary) and its volume. Facade sets requiring more labor and materials will result in a higher overall cost, compared to simple massing. The addition of a floor, and / or a garage, will also influence the final price. On average, a two-storey house is 15% more expensive than a single-storey house.
Fittings Interior fittings also affect the cost of the home. For example, high-end tiles can reach 200 € / m², compared to the usual average price of 15 to 20 € / m². The same goes for the kitchen and the masonry, it all depends on the customer’s wishes.
