Pergola Design
Our pergolas combine aesthetic appeal with functional shade solutions. Using weather-resistant materials and patented joinery techniques, we create structures that endure Canadian climates. Clients receive photorealistic 3D models to visualize designs before construction begins.
Deck Construction
We build low-maintenance decks using premium lumber and hidden fastening systems. Our designs prioritize safety with non-slip surfaces and code-compliant railings. Each project includes permit documentation and lifetime durability guarantees.
Cabana Building
Custom cabanas feature full kitchens, washrooms, and climate control systems. We incorporate energy-efficient insulation and waterproofing membranes to ensure year-round usability and structural integrity in all weather conditions.
Fence Installation
Our fences use pressure-treated posts and cedar rails with lifetime guarantees. Installation includes soil stabilization techniques to prevent shifting, ensuring structures remain straight and secure for decades.
DIY Plans
Downloadable 3D plans include scalable templates and step-by-step instructions. Each package provides material lists, cutting diagrams, and assembly sequences to simplify complex builds for experienced DIYers.

It was an absolute pleasure working with Lawrence Winterburn to create our dream outdoor living space. Lawrence is the ultimate professional. From beginning to end, he presented us with several different options and listened intently to all of our needs for the space, creating the ultimate living and dining spaces. His passion for design is exemplary. We are so appreciative of the effort and creativity in transforming our backyard and in creating a beautiful deck for our family and friends to enjoy for many years to come. The deck is truly a magnificent extension of our indoor space. Lawrence,

This young man went out of his way to share his knowledge and experience with garden arches & gates with me over the phone - without the least notion that I would actually be able to hire him. I am not at all sure that I can win my husband over to the idea, but if I ever do, I would hire this man in a minute for obvious love of creating beautiful garden structures. That kind of passion and generosity of spirit is hard to find.

Lawrence from Gardenstructure is an expert craftsman. He is able to come up with beautiful computer rendered designs and then build his design to almost perfectly match. As with all construction, issues can arise, but rest assured Lawrence will sort them out. Reliable and a pleasure to work with, and that's hard to find in construction.
