Building a shed may seem like a simple project at first glance, but it contains many subtleties that shouldn't be overlooked. Whether it's for storage, a workshop, or even a small living space, building a shed must be well thought out to avoid costly mistakes or future disappointments.
At Plan Maison Québec, we regularly assist our clients in the design and completion of their projects, whether they're houses, cottages, or cabins. Today, we're sharing a comprehensive guide on the mistakes to absolutely avoid when building your shed.
Understanding the specific issues involved in building a shed
Building a shed in Quebec requires a thorough understanding of several environmental and regulatory factors specific to the region. Indeed, long, harsh winters, sometimes hot and humid summers, and frequent freeze-thaw cycles impose specific technical constraints. Weather resistance must be a key consideration during design. An ill-adapted shed risks quickly suffering from water infiltration, wood rot, or even peeling exterior siding.
But beyond the climate, the geographic location of your land, wind exposure, soil type, and the potential presence of waterways also influence the design. For example, a sloping lot requires reinforced foundations, while clay soil requires special attention to prevent ground movement.
Plan Maison Québec also emphasizes the importance of the shed's visual integration into its surroundings. A shed designed without aesthetic consideration can look out of place in a residential neighborhood or natural setting. The choice of colors, materials and shapes must therefore take into account the surrounding architecture and the owner's preferences.
Neglecting planning: a fatal mistake
Starting a project without a precise plan often means building on shaky foundations. Planning isn't limited to sketching the outline of the shed; it also includes a thorough consideration of actual needs, site constraints, budget, and deadlines.
Careful planning helps avoid unpleasant surprises. For example, a shed that's too small for the intended use will require a review of the project during construction, generating additional costs and wasted time. Similarly, ignoring the necessary access points for tools or equipment to be stored can make the shed impractical.
At Plan Maison Québec, we always recommend establishing precise specifications. They must include:
the primary use (storage, workshop, office, etc.)
the exact dimensions
whether insulation is required
the type of electricity or plumbing, if necessary
the specific constraints of the site.
Additionally, this step allows for better communication with contractors and suppliers, accurate quotes, and control over the overall project budget. Without solid planning, the risk of financial overruns is high.
Ignoring local permits and regulations: a trap to avoid
In Quebec, each municipality has its own urban planning by-laws governing the construction of outbuildings such as sheds. These regulations aim to ensure safety, preserve the harmony of the landscape, and protect neighbors. For example, regulations may limit the maximum surface area of a shed, impose a minimum setback from property lines, or require specific materials.
Failure to comply with these standards can result not only in administrative penalties but also in the need to demolish or modify the shed. This type of situation is unfortunately common among those who overlook this step.
Plan Maison Québec reminds us that submitting a building permit application is often mandatory as soon as the surface area exceeds a certain threshold, generally around 10 square meters, but this can vary. Even for smaller projects, it is prudent to check.
Consulting experts or consulting municipal services can help avoid these pitfalls. Plan Maison Québec supports its clients in this process, ensuring that the project meets all legal requirements, which guarantees a smooth construction without unpleasant surprises.
Underestimating the importance of foundations
The role of the foundation is crucial, as it supports the entire structure of the shed. A poorly designed or insufficient foundation can quickly cause visible problems such as subsidence, cracks, and even warping of the walls.
In Quebec, where the ground is subject to frost, it is essential that the foundations be deep and strong to avoid heaving caused by frost (a phenomenon called "differential heave"). The recommended depth generally varies between 36 and 48 inches, depending on local standards.
Furthermore, the type of foundation also depends on the soil type and the size of the shed. For a small, lightweight shed, concrete block or piling foundations may be sufficient. For a heavier or insulated structure, a concrete slab is preferable, providing stability and a clean base for installing siding.
Plan Maison Québec also recommends providing good drainage around the foundation to prevent waterlogging, which accelerates the deterioration of materials and can cause water infiltration.
Choosing materials unsuitable for the Quebec climate
The longevity and performance of a shed depend largely on the choice of materials. In a climate like Quebec's, materials must withstand humidity, cold, UV rays, and temperature variations.
Wood remains the most commonly used material for its ease of installation and aesthetic appeal. However, it must be treated to resist rot, insects, and fungi. Untreated wood quickly loses its qualities and becomes brittle.
Insulation panels also play an essential role in maintaining a stable indoor temperature. Using suitable insulation, such as rigid foam or mineral wool, helps protect against cold and humidity.
Similarly, exterior cladding must be durable. Vinyl, steel, or composite cladding offers good strength, but their quality varies depending on the supplier. Durability and maintenance should be considered when choosing a shed.
At Plan Maison Québec, we systematically recommend proven materials that are adapted to the climate, to ensure a durable construction that requires little maintenance in the medium and long term.
Poor insulation and insufficient ventilation
A shed that isn't properly insulated not only provides poor protection against the cold, it also risks moisture accumulation, which can lead to mold and rapid structural deterioration.
Thermal insulation isn't always a priority for a shed, especially when it's used solely for storage. However, in regions of Quebec, even a small, unheated space can suffer frost damage if the interior temperature isn't regulated.
Insulation must therefore be designed based on the shed's intended use. If you plan to spend time in it, insulating the walls, ceiling, and floor is essential. It also helps reduce heating costs if you install an electric system.
At the same time, well-designed ventilation is essential to evacuate interior moisture. A lack of ventilation creates a humid environment, promoting the growth of mold and wood deterioration.
Plan Maison Québec recommends incorporating ventilation grilles and, if possible, a lightweight mechanical system to ensure regular air exchange. This preserves air quality and the longevity of your shed.
Mistakes in interior space design
The design of a shed's interior space is often underestimated, even though it plays a key role in the functionality and longevity of your installation. A poorly designed space can quickly become cluttered, impractical, and frustrating to use, transforming what should have been a place for organization and storage into a source of stress.
At Plan Maison Québec, we emphasize the importance of anticipating specific needs before even drawing up the plans. This starts by clearly defining the shed's primary use: is it a simple storage space for gardening tools and equipment, a DIY workshop, or a small office or relaxation area?
This definition directly influences the size, wall layout, and the integration of storage solutions.
Optimizing vertical space is often overlooked. Installing sturdy shelves, pegboards for hanging tools, or even hanging cabinets can free up floor space and better organize items. For example, a lawnmower can be parked under a work surface, while wall hooks can hold garden hoses or ladders.
Natural lighting also deserves special attention. Placing well-oriented windows or skylights not only saves electricity but also creates a more pleasant environment. A bright shed makes people want to spend time there and facilitates manual activities. If the shed is intended to be used in the evening or in winter, it's also important to provide efficient, well-distributed electric lighting adapted to the different areas.
Finally, don't forget access points. A door that's too narrow or poorly positioned can make it difficult to get large items, such as a barbecue, trailer, or bicycle, in and out. Considering double doors, a sliding door, or a secondary entrance can greatly facilitate daily use.
Forgetting about aesthetic integration into the property
A shed shouldn't just be a functional addition: it must blend harmoniously into the overall architectural and landscape design of your property. Ignoring this aesthetic dimension is a mistake that can harm the value of your land and the pleasure you'll have in admiring it.
Plan Maison Québec recommends considering the shed as a natural extension of your house or cottage. The choice of materials, colors, and shapes should harmonize with the overall style. For example, for a traditional wooden house with a tiled roof, choosing a shed with natural wood finishes or painted in similar tones will reinforce the visual unity.
Architectural details also count. Elements like ornate gables, decorative shutters, or windows that match those of the house add charm and aesthetic coherence. These small touches make all the difference between a shed that seems "stuck" to the property and a tastefully integrated building.
Beyond the structure, it's important to consider the shed's immediate surroundings. Incorporating landscaping, such as a plant border, a small path, or even an adjoining deck, can soften the transition between the building and the garden. This type of design helps create a pleasant space and enhances the overall property.
Finally, the location of the shed must also be carefully considered to preserve the view and the brightness of the house. A careless shed placement can obscure a beautiful view or create an annoying shadow.
Neglecting future maintenance
Careful maintenance of a shed is often the key to its longevity and beauty. Yet, many owners underestimate this aspect, mistakenly believing that the construction alone is enough to guarantee the durability of their property.
Regular maintenance should be planned for from the design stage, by choosing materials that are easy to clean and resistant to weather and insects. For example, pressure-treated wood or composite siding will require much less maintenance than unfinished wood.
A thorough annual cleaning of the shed, including the roof, gutters, windows, and doors, helps prevent debris accumulation and the growth of mold or mildew. Regularly inspecting joints and fasteners helps quickly detect areas of wear or weakness.
Wood treatment, whether varnished, painted, or stained, should be renewed approximately every 2 to 3 years. This simple step significantly extends the lifespan of wooden surfaces by protecting them from moisture and UV rays.
Monitoring the condition of the roof is also essential. A leak or poorly secured tiling can quickly cause significant damage to the interior of the shed, as well as accelerated deterioration of the wooden structures.
Finally, don't forget ventilation. Insufficient ventilation can lead to moisture buildup, which can lead to mold growth and deterioration of materials. Regular inspection and cleaning of ventilation grilles can prevent these problems.
At Plan Maison Québec, we strongly recommend incorporating a simple and appropriate maintenance plan from the design phase onwards, so that your shed retains its new appearance and functionality for many years.
