How much does an architectural project for a detached house cost?

The process of building a detached house is an exciting adventure, but it can also be overwhelming, especially with regard to the associated costs. One of the most important and often least understood aspects is the cost an architectural project entails. In this blog post, we will break down the factors that have an impact on the cost of an architectural project for a detached house and provide an overview of what you may expect.

Factors that have an impact on costs Geographical Location

The cost of living and professional standards vary greatly between regions. For instance, architectural services in a large city, such as Madrid or Barcelona, may be more expensive than in rural areas or smaller cities.

Project size and complexity

The total floor area of the home, the number of floors, the complexity of the design and specific architectural details have a direct impact on costs. Larger and more complex projects will require more time and resources, which increases the total costs.

The architect’s experience and renown

Architects with extensive experience and a solid reputation on the market tend to charge more for their services. However, their expertise can result in a more efficient and higher quality design, with ensuing long-term savings.

Services 

The services offered can range from conceptual design to construction supervision. A comprehensive project that includes all design and construction stages will be more expensive than one that only covers the design stage.

Materials and technologies

The choice of high-quality materials, cutting-edge technology for energy efficiency or home automation systems can significantly increase the project costs.

Cost breakdown

The following is a general breakdown of the costs associated with an architectural project for a detached house:

Initial enquiry and conceptual design

This initial stage can amount to 500 to 2,000 euros, depending on the project complexity and the architect.

Project development and floor plans

Detailed floors plans and construction documents can cost between 5% and 15% of the home’s total construction cost. For example, if your home costs 200,000 euros, you could pay between 10,000 and 30,000 euros at this phase.

Permits and licences

Getting the necessary permits and complying with local regulations can cost between 1,000 and 5,000 euros, depending on the location and project nature.

Construction supervision and management

If you decide to hire the architect to supervise the construction, this can add 5% to 10% to the total project cost.

Total budget estimate

To get a clearer picture, an architectural project for a medium-sized detached house (approximately 150–200 m²) in Spain can cost between 15,000 and 50,000 euros in total. This includes all stages, from initial design to construction supervision.

Tips to optimise costs Set a clear budget

From the outset, set a clear budget and be sure to submit it to the architect so that they can work within those limits.

A clear and detailed design from the outset can avoid costly changes during construction.

Consider energy efficiency

Investing in design and materials that improve your home’s energy efficiency can afford significant savings in the long run.

Conclusion

The cost of an architectural project for a detached house can vary widely, depending on a number of factors. However, with careful planning and the right choice of professionals, you can achieve the home of your dreams within your budget. Please remember that investing in good architectural design not only improves the quality of life, but also increases your property’s long-term value.
