Permit-Approved Two-Level Composite Deck with Waterproof System

Mississauga
Completed November 2025

This project involved the design and construction of a fully custom two-level composite deck completed through a formal permit process, including detailed drawings, submission, and municipal approval. All structural plans were prepared in accordance with local building code requirements. Permit applications were submitted, reviewed, and approved prior to construction, ensuring full compliance with safety and engineering standards. The finished structure features upper and lower composite deck levels, built using high-performance decking boards engineered for long-term durability. The perimeter is completed with aluminum glass railing, delivering modern aesthetics and unobstructed views. A fully integrated waterproof drainage system was installed beneath both deck levels to protect structural components and maintain dry, usable space below. The underside of the upper deck was enclosed with a finished soffit ceiling system, incorporating hardwired recessed spotlights for ambient illumination. The lower level, with approximately four feet of clearance, was enclosed using smart panel cladding to create secure and functional storage space. All structural framing was carefully concealed, and support posts were wrapped in composite material to eliminate exposed wood surfaces. The result is a permit-approved, engineered outdoor structure built to the highest standards of durability, safety, and craftsmanship.

Scope

Preparation of structural drawings, permit submission and approval process, and construction of a two-level composite deck featuring aluminum glass railing, full waterproof drainage systems, enclosed under-deck storage, finished soffit ceiling with integrated lighting, and composite-wrapped structural posts.

Challenge

The project required full permit approval, including structural drawings and compliance with building code regulations. Integrating waterproof systems across two deck levels while enclosing the underside with soffit and lighting demanded precise engineering coordination to maintain drainage performance, ventilation, and long-term structural stability.

Result

A fully permit-approved two-level composite deck featuring waterproof protection, enclosed storage, finished soffit ceiling, and modern glass railing — delivering structural integrity, compliance, and refined outdoor living.

Composite Deck with Privacy Screens & Aluminum Railing

This project involved the construction of a premium elevated composite deck designed to extend the home's second-floor living space while maximizing privacy, functionality, and modern curb appeal. Built using high-performance composite decking, the deck features a professionally crafted picture frame border, creating a clean architectural finish that highlights the deck's shape and craftsmanship. For enhanced privacy, custom composite privacy screens were installed on both sides of the deck, creating a more comfortable outdoor environment without compromising the open feel of the space. The remaining perimeter was completed with durable black aluminum picket railing, providing safety while maintaining unobstructed views of the backyard. The deck includes a spacious landing that transitions into a custom staircase equipped with a matching aluminum gate, offering secure and convenient access to the yard below. Every detail from the precision picture frame installation to the seamless integration of the privacy screens, railing system, landing, and staircase was carefully executed to create a refined, low-maintenance outdoor living space built for years of enjoyment.

Downtown Backyard Wood Deck with Privacy Screens & Fence Upgrade

This project involved the construction of a custom wooden deck for a downtown Toronto home situated on a narrow urban lot with a compact backyard. Designed to maximize functionality within limited space, the deck provides structured outdoor living while maintaining privacy and accessibility. A side-entry staircase allows access from the front passageway, while a rear staircase with integrated gate provides direct backyard exit. To enhance privacy between closely spaced neighboring properties, privacy screens were installed along both sides of the deck. The rear boundary was enclosed with new fencing, creating a defined and secure outdoor area. Additionally, the left-side property line fence was replaced and upgraded to improve visual consistency and structural integrity alongside the new deck build. The result is a refined urban backyard solution that balances space efficiency, privacy, and durable wood craftsmanship within a tight downtown setting.
