What Determines an Architect's Fees ?

It's essential to note that architect fees are not regulated. Indeed, an architect has the freedom to set the amount of their remuneration. This depends on the type of apartment or house renovation works you wish to undertake. However, an architect's fee generally depends on three main factors, among which are :

Project Complexity

If the architect has to work on a challenging site, their fees will be higher. This also applies if the site is rather extensive. 

Cost of Works 

The higher the cost of the works, the higher the architect's fees will be. Remember, the architect's services are charged as a percentage !

Scope of the Mission

If the architect has to work on a long and relatively complex project, the cost of their services will increase accordingly.

Architect's Qualification 

The price also varies depending on whether it is a DPLG architect, a DE-HMONP architect, or DE architect. 

As you can see, the architect's price depends on the cost of the works. It is therefore necessary to determine the total cost of the works to know how much the architect's service will amount to. For a more precise estimate of the architect's final fee, it is advisable to wait until the end of the works.

Can an Architect's Price Be Changed ?

It is possible to increase an architect's prices under certain circumstances. 

Changes to the Original Project 

Modifications may have been made to the project along the way. For example, materials may have been replaced, or plans may have been corrected. In this case, the architect's price will take into account the cost of the modifications made to the project. 

Expansion of the Mission Scope

If there has been an expansion of the mission scope, such as the addition of new tasks, the architect's fees will be revised accordingly.

Increase in the Cost of Works

If the architect's fees are based on a percentage of the cost of the works, they will be adjusted in case of an increase in the final cost of the works.

How Are Architect Prices Calculated ?

Here's how to calculate architect fees :

Percentage Calculation of Cost of Works 

For a complete architect service or a specific mission, the architect's fee will be calculated as a percentage. This ranges between 8 and 15% of the total cost of the works.

Flat Rate Calculation for Small Projects

This type of remuneration is preferred if the mission and project are defined in advance. Also, the site must have a total area of less than 150 m². 

Hourly Rate Calculation 

With this method, the architect's price is calculated based on the time spent on the construction site and, therefore, on the project. It is recommended for short-term missions.

Several remuneration methods can be used depending on the requested mission. Feel free to consult the architect's quote to verify their calculation method. It should also be noted that architect fees must be added to the VAT. The VAT rate varies depending on the renovation works to be carried out : 

  • – For an extension, construction, or study of a house: 20% VAT,
  • – For renovation works: 10% VAT,
  • – For energy renovation works: 5.5% VAT.

Some Examples of Architect Prices

Here are some price examples to give you an idea :

House Plan Price 

The price of a house plan created by a professional architect is determined based on the services offered and their level of expertise. If the architect's hourly rates are between €50 and €70/m², some providers charge from €2500 for the complete design of house plans. This price varies depending on the project's complexity. 

Building Permit Price

The average price of a building permit prepared by an architect is €1,500 to €3,500. This price is estimated at around €55 excluding taxes per square meter, excluding administrative fees. These fees vary depending on the city and the size of the project.

How Does an Architect Bill for Their Services ?

The billing of an architect's services can vary depending on several factors, including the nature of the project, the preferred billing method of the architect, and the client's preferences. In the case of renovation projects, interior architects may opt for several billing methods. The most common method is hourly fees, where the architect charges a fixed rate per hour worked on the project.

This method is often used for projects with variable client needs that may evolve over time. Another common billing method is a flat fee, where the architect proposes a fixed price for the entire project. It is recommended to openly discuss billing options at the beginning of the process to avoid any confusion or misunderstanding later on.

Where to Find the Best Architect Prices ?

To find the best architect price for your renovation project, it is essential to conduct thorough research and compare different available options. Several sources can be explored to find the architect offering the best value for money.

Seek Multiple Architect Quotes

Start by seeking quotes from multiple architect firms. This will give you a precise idea of architect fees, the project manager, and the client's fees, as well as the rates practiced in the market. Provide as many details as possible about your project to ensure that the quotes are as accurate as possible. This strategy is valid when estimating the budget for your project, for example, to get a roof renovation quote.

Leverage Your Personal and Professional Network

Next, don't hesitate to tap into your personal and professional network for recommendations. Ask your friends, family, or colleagues if they have ever worked with an architect they would recommend. Personal recommendations can often be a valuable source of reliable information about the quality of work and rates charged by an architect.

Explore Online Platforms

Additionally, explore online platforms specializing in connecting clients with construction professionals, such as interior architect websites or online quote platforms. These platforms allow you to quickly compare architect prices and services offered by different professionals, which can help you find the one that best suits your needs and budget.

Taking Experience into Account

Lastly, don't forget to consider the architect's reputation and experience during your search. An architect with solid experience in managing renovation projects similar to yours may be able to offer you better value for money, even if their fees are slightly higher.

Which Architect to Contact for Renovation Work ?

To choose the right architect for your renovation work, several aspects need to be considered :

Specialized Architect

First and foremost, it's essential to look for a professional specialized in renovation projects. They should have proven experience in this specific field. An interior architect or an architect specializing in renovation understands the unique challenges posed by this type of project. They will be able to offer creative and effective solutions to maximize the use of your space.

Architect Providing Accurate Quotes

Next, it's important to consider the price of an architect and their fees. Request multiple quotes from architects to compare rates and services offered. Keep in mind that the total cost of the work should not be the only selection criterion. The quality of the work and the architect's reputation are also factors to consider.

Architect Attentive to Your Needs

When hiring an architect for your renovation work, make sure to choose a professional with whom you feel comfortable and confident. Communication is a key element of a successful collaboration, so ensure that the architect understands your needs, preferences, and budget constraints. Ask questions about their working process, design methodology, and availability to oversee the project from start to finish.

Reputable Architect

Finally, don't hesitate to ask for references and check the architect's past achievements. This will give you an idea of their style, aesthetics, and ability to meet client expectations.

Entrust Your Renovation Project to an Expert Architect 

In conclusion, choosing an architect for your renovation project will have a significant impact on the final result. The selection process should therefore take into account the price of the architect and their fees. Throughout this article, we have delved deep into the various components related to this issue. So, when you are searching for an interior architect, keep in mind that price should not be the sole deciding factor.

While budget is important, it is also essential to consider the quality of work, the architect's expertise, and compatibility with your vision and needs. Finding the right balance between the architect's fee and the value they add to your project is therefore the key to a rewarding collaboration. By engaging an architect for your renovation project, you are investing not only in the physical transformation of your space. The expertise and vision of a professional can make all the difference.

Ultimately, whether you are looking for an architect for a residential or commercial project, it is important to take the time to conduct thorough research. You should also seek recommendations and meet with several professionals before making a decision.
