Building or renovating a house, cottage, or garage is an exciting yet complex project that requires meticulous preparation. One of the crucial steps is the design of the plans, the backbone of your project. At Plan Maison Québec, we understand that creating a house plan is much more than a simple drawing: it's a concrete representation of your ideas and needs, and an essential guide for the professionals who will work to make your dream a reality.
But who can really create a house plan? Is it absolutely necessary to hire a professional, or are there accessible alternatives? This article offers a comprehensive overview of possible solutions, with a particular focus on the Quebec context.
Understanding the importance of the house plan
The house plan is the cornerstone of any construction or renovation project. It not only establishes the layout of the spaces, but also defines the dimensions, orientation, and technical details essential to the construction of the building. Without a clear and precise plan, it is nearly impossible to effectively coordinate the various trades involved and obtain the necessary permits from municipalities.
At Plan Maison Québec, we emphasize the importance of a carefully prepared plan, as a poor plan can have serious consequences: additional costs, extended deadlines, and even non-compliant work. The plan is also an essential communication tool between you, the contractors, engineers, and authorities. It helps avoid misunderstandings, clarify each step, and ensure the coherence of the entire project.
Beyond the technical aspects, a good plan reflects your expectations and lifestyle. It takes into account interior circulation, brightness, storage space management, and even the possibilities for future development of the house or cottage. At Plan Maison Québec, we believe that a well-thought-out plan is the best guarantee for your home to reflect your personality and be comfortable in the long term.
Who can make a house plan? The essential professionals
Designing plans is a technical task that requires specific skills and a good understanding of construction regulations. This is why, traditionally, this task is entrusted to qualified professionals. Each participant brings a different expertise that ensures the project is both feasible and compliant with current requirements.
1 . Architects
The architect is often seen as the artistic creator of the project. They combine creativity and technique to develop a unique plan, tailored to your needs and the context of your property. Their role goes beyond simply drawing up plans: they can also advise you on the choice of materials, landscaping integration, and environmental aspects. In Quebec, hiring an architect is often essential for ambitious projects or projects in protected areas.
Hiring an architect at Plan Maison Québec not only guarantees an aesthetically pleasing and functional plan, but also rigorous compliance with standards, particularly those related to energy performance and sustainability. The architect supports you throughout the process, from design to construction supervision, offering you valuable peace of mind.
2 . Architectural technologists
Architectural technologists are both technical and practical professionals. Their training allows them to produce detailed and accurate plans, often at a more affordable cost than an architect. They are particularly skilled in standard construction, expansions, or renovation projects that do not require a highly sophisticated architectural approach.
At Plan Maison Québec, we regularly collaborate with technologists, as they represent an excellent compromise between quality, efficiency, and budget. Their mastery of computer-aided design (CAD) software ensures plans that are tailored to the building's requirements and comply with municipal standards.
3 . Interior designers and draftsmen
For projects focused on interior design or partial renovations, interior designers and technical draftsmen play an important role. They optimize space utilization, improve circulation, and ensure that aesthetic choices are consistent with technical constraints. These professionals often work in tandem with architects or technologists to finalize comprehensive and feasible plans.
4 . Engineers and other specialists
In certain situations, particularly when the building structure is complex or the terrain presents particularities, the intervention of civil or structural engineers becomes essential. Their analysis ensures that the plans comply with safety standards, particularly in regions prone to earthquakes or heavy snow loads, which are common in Quebec. They are often involved in the technical validation of plans drawn up by other professionals.
Can you make your own house plan?
With the advent of digital technologies and the widespread availability of design software, many individuals are wondering about the possibility of designing their own house plans. This approach, if properly supervised, can be a viable option, especially for simple projects.
Why make your own plan?
Creating your own plan can lead to significant savings, as the cost of professional services is often significant. Furthermore, this approach offers great freedom: you retain control over the design, can test different configurations, and quickly adjust spaces according to your needs. This also increases your involvement in the project, which is often a source of satisfaction.
Furthermore, for smaller construction projects such as a garage, carport, or small cottage, a personal design is often sufficient, especially if you have a good grounding in drawing and use the right tools.
Limitations to consider when making your own plan
1 . Technical and regulatory complexity
Creating a house plan yourself may seem accessible thanks to modern tools, but it remains a demanding technical task. It's not enough to simply design walls and windows: you must take into account structural constraints, safety standards, thermal requirements, and Quebec's specific urban planning regulations.
For example, you must plan for adequate load-bearing walls, respect the minimum setbacks imposed by the municipality, and ensure sufficient ventilation. Ignoring these elements can result in permit rejections or significant costs associated with subsequent corrections.
2 . Risks associated with misinterpreting standards
The Quebec Construction Code is dense and evolving. Untrained individuals can easily misunderstand requirements for insulation, accessibility, or water management. Incorrect thermal insulation calculations, for example, can result in high energy costs and make the home uncomfortable in winter.
Furthermore, certain standards regarding fire safety and structural strength are mandatory and must be scrupulously respected.
3 . Lack of experience to anticipate problems
A plan designed without professional experience can overlook essential aspects such as smooth circulation throughout the house, optimal orientation for natural light, or even technical connections (electricity, plumbing). These oversights often lead to costly modifications during the construction phase. Experience also allows for the anticipation of future needs, such as a possible expansion or energy improvements.
4 . Lack of guarantee and professional insurance
Unlike plans drawn up by architects or technologists, homemade plans do not benefit from a professional guarantee. In the event of major defects, you will have no recourse to an expert to correct or compensate for errors. This lack of protection can expose you to litigation, additional costs, or even safety issues.
Free software for drawing your house plan
Fortunately, technology makes this process much easier. Several free and online software programs allow you to create clear plans and even view them in 3D, which helps you better understand the volumes and layout.
1 . SketchUp Free
SketchUp Free is one of the most popular tools for 3D modeling. Its intuitive interface allows you to quickly draw three-dimensional plans, which is an advantage for visualizing the entire project. It is particularly appreciated for its active community and the numerous tutorials available.
2 . Sweet Home 3D
Sweet Home 3D is a simple solution, ideal for beginners. It offers a user-friendly interface for drawing walls, doors, windows, and furnishing the interior. This allows you to easily experiment with different layouts.
3 . Floorplanner
Floorplanner is a very useful web application that offers a free, full-featured version for creating simple floor plans. Its 3D rendering feature allows you to visualize the space and assess the ergonomics of rooms.
4 . HomeByMe
HomeByMe stands out for its extensive object library, which allows you not only to draw plans, but also to virtually furnish and decorate your home. This feature is an asset for better visualizing the final result.

Tips for a successful DIY home plan
If you opt for a custom design, be sure to carefully study local regulations. It's crucial to check minimum dimensions, required setbacks, and current energy standards. Be precise in your measurements and don't hesitate to consult guides or professionals to validate certain technical aspects. Keep in mind that the plan must be clear, understandable, and usable by the contractors who will carry out the work.
Permits required to build or renovate
An essential aspect to consider when drawing up a house plan is the issue of permits. In Quebec, it is mandatory to obtain a building permit before beginning any major project, whether it's new construction, a major renovation, or an addition. This permit is issued by the municipality and ensures that your project complies with current construction, safety, and urban planning standards.
The house plan serves as the key document in the permit application. It must be sufficiently detailed to allow authorities to verify the project's compliance. Without compliant plans, the application may be denied, which will significantly delay your work.
In some cases, for simple or minor projects, such as the construction of a temporary shelter or an interior renovation without structural modifications, a permit may not be required. However, it is always recommended to check with your municipality to avoid any violations.
Furthermore, Quebec legislation requires that certain work be carried out or supervised by licensed professionals. For example, for major renovations, you may be required to provide plans signed by an architect or technologist, which ensures compliance with technical and regulatory requirements.
At Plan Maison Québec, we also assist you with this administrative process. We ensure that your plans comply with municipal criteria and are ready to be submitted for quick permit applications. This avoids unpleasant surprises and allows you to begin construction or renovations legally.

Standards and regulations: what you need to know
In Quebec, compliance with construction standards is a legal obligation that guarantees the safety and quality of buildings. The Quebec Construction Code details requirements for thermal insulation, material strength, accessibility, and environmental compliance. Furthermore, each municipality may apply its own rules, often related to urban planning, zoning, and architectural harmony.
At Plan Maison Québec, we carefully integrate these standards into each of our plans. This approach avoids unpleasant surprises, speeds up the process of obtaining permits, and secures your investment.
Common Mistakes to Avoid When Designing Plans
1 . Error in proportions and dimensions
One of the most common mistakes is improperly sizing spaces. Rooms that are too small, narrow hallways, or poorly placed openings can make a home uncomfortable. Poorly estimating usable space or failing to meet minimum standards leads to a poorly functional home, which directly impacts quality of life.
2 . Bad orientation of the house
The position of the house on the land has a significant impact on its thermal and lighting comfort. Poorly planned orientation can lead to a lack of natural light, overheating in summer, or heat loss in winter. Optimizing orientation also helps reduce energy costs by better utilizing the sun. This is an aspect often overlooked by non-professionals.
3 . Neglect of technical networks
Home-built plans often fail to properly integrate electrical, plumbing, heating, and ventilation systems. This oversight complicates the completion of the work and can lead to additional costs or delays. Additionally, poor installation placement can make maintenance difficult or increase energy consumption.
4 . Omission of municipal and urban planning constraints
Each municipality imposes strict rules regarding maximum heights, setbacks from property lines, and the exterior appearance of buildings. Ignoring these constraints can result in the rejection of the permit application or even the obligation to demolish or modify part of the building. Therefore, precise knowledge of these rules is essential during design.
5 . Underestimating future scalability
An overly rigid plan that doesn't allow for future adaptations can limit your home's value. For example, it's often recommended to consider flexible spaces or expansion options. Ignoring this aspect can quickly render a project obsolete as family needs change.
