Custom home plans
How your custom home plan comes to life
Building a unique house is a work of art by itself, and it all starts with an exclusive house plan. Its design goes through a process where inspiration is the beginning of free creativity. In order to bring to life dignified and inspiring spaces, we are always at the forefront of trends and planning with your needs and lifestyle in mind.
Planning to build a house or extend your home? Our team guides you through the design of custom plans, taking into account your lifestyle, your lot and your budget.

Step 1 : Design meeting
At our office, we take the time to clarify your vision: the spaces you want, your lifestyle, your aesthetic preferences and your priorities. This meeting lays the foundations for the design of your home.
Like around a fireplace, talking about you and your project
At the first meeting, we invite you to talk about yourself and your project. Like around a fireplace, we will discuss ideas, budget, style and your tastes in the comfort of an open atmosphere. This step is essential in the creative process as the designers’ vision is combined with your dream of a home designed exclusively for you.
In order for you to embrace the pleasures of the present moment, our designers listen to your story. This artistic approach allows us to know your needs, tastes and lifestyle both inside and outside your home.
The important information we discuss:
- The architectural style
- The number of rooms
- The interior layout
- The exterior layout
- Your budget
- Your tastes

Step 2 : Site analysis and siting
We visit your lot and examine the characteristics that will influence the project, in particular the topography, orientation, sunlight and views. This analysis helps us think about where to place the house and how to organize the spaces.
For an addition, we also study how it will integrate with the existing building.
Natural light, at the heart of our concepts
Our designers always orient the house according to the morphology of the landscape in order to let in the natural light that will surround you, while inspiring you. The heart of a home’s life is the light that inhabits it: that’s why the orientation and the windows of the house are of great importance to us in our concepts.
What we analyze:
- Topography
- Orientation
- Sunlight
- Views
- The existing building

Step 3 : Preliminary design and presentation
We develop the floor plans, the exterior elevations and a 3D model to help you visualize the project.
The concept is presented to you to validate the configuration of the spaces, the architectural style and the main directions. We then refine it with you based on your comments.
Visualizing the 3D interior and exterior renderings
These renderings show you the proposed concept for the interior spaces and especially the motion and fluidity in your movements within these spaces. This also leads you to understand the action and benefits that natural light will bring to the interior spaces. Whether it is a country or urban house, the 3D exterior visualization conceptualizes the chosen design.
What we present to you:
- Floor plans
- Exterior elevations
- 3D model
- Architectural style
- Configuration of the spaces
Any necessary changes can be made to the proposed concept and layout: the process is iterative and collaborative.

Step 4 : Preliminary cost estimate
Based on the chosen concept, we prepare a first estimate of the construction costs. It allows us to check that the project matches your budget, then to determine the adjustments to make before moving forward.
Materials that express the nature around us
The previous steps have confirmed the shapes and living spaces. We must now bring life to these spaces with quality materials that express the nature that surrounds us. The effect of the chosen materials must represent the people who live there. The materials we use will express what you are looking for in terms of atmosphere.
The estimate takes into account:
- Exterior cladding
- Interior materials
- Finishes
- The scope of the work
- Your budget

Step 5 : Producing the technical plans
Once the concept is approved, we prepare the technical plans included in the mandate: foundations, levels, elevations, sections, roof and construction details, according to the needs of the project.
The final file is handed over to you for the next steps.
When you arrive at the house, you will have that feeling of being truly at home.
The long-awaited moment has arrived. You will be presented with the plans and specification documents, while also taking the time together to review the final drawings and documents as well as the materials and furniture.
What you receive
- Three copies of the plans in 24 × 36 format;
- A digital copy of the plans;
- The construction specifications;
- The materials, furniture and decoration specifications.
The technical file includes, depending on the project:
- Foundations
- Levels
- Elevations
- Sections
- Roof
- Construction details
If your mandate includes interior design, we continue with the detailed layout of the spaces and the selection of materials. This work can begin during the architectural design to ensure the coherence of the whole.
