Do business with Construction Précellence for the construction of your outdoor terrace on your duplex/triplex!

When you own a duplex or triplex, building an outdoor terrace is not only interesting for your tenants, but also adds considerable value to your building. However, it is better to entrust the construction of your outdoor terraces (especially if they are on two or three different floors) to professionals. At Construction Précellence, we offer you a turnkey service for the construction of outdoor terraces for duplexes and triplexes, adapted to your needs and budget. Composed of architects, designers, engineers and renovation consultants, our team will assist you at each step to help you structure a complete plan: first home consultation, choice of terrace type, work schedule and schedule, demolition, supervision of workers, repair, cleaning, disposal of materials, post-contract monitoring, etc.

What are the important elements to consider when building your terrace?

Before starting your project, it is important to define a few elements so that your terrace is as you imagined it. Our design and construction team will be pleased to guide you!

  • Deck size: With your construction consultant, you can calculate the approximate size of your deck, so that there is enough space for the activities you plan to do (outdoor kitchen, outdoor fireplace, dining area, pool deck, terrace with screen) and the number of people who will use this space.
  • Multi-level terrace: If your property is sloping or your terrace has areas that delineate different activities, a multi-level terrace is an ideal solution. The construction of a multi-level or multi-section terrace may require a permit (which we will take care of)
  • Terrace Anchorage: In the vast majority of cases, terraces are attached to the house, the latter serving as an essential component of the structural system. In the case of a terrace anchored to the house, it is necessary to create concrete pillar foundations without a footing.
  • Access: The different accesses to the terrace are an important component of its creation. Stairs can be designed in many ways, for example, in a corner of the terrace, or wide enough to serve as benches and not require a handrail.
  • Roof structure : By covering your terrace with a roof, you will have more shade and can benefit from outdoor lighting. Also, if you add mosquito nets, you will enjoy optimal peace of mind.

There are a wide range of materials on the market that can be used to build your terrace. Here is an overview of the most commonly used materials for outdoor terrace construction:

  • Pressure-treated wood
  • Cedar tree
  • Sequoia
  • Ipe (Green ebony)
  • Vinyl
  • Euro pressure treated wood tiles
