Multi-Use Waterproof Deck with Elevated Aesthetic and Functionality

- High Clearance & Cedar CladdingThe entire lower level was cladded in cedar tongue & groove and raised to the maximum height to provide comfortable headroom.
- Porcelain Tile DeckingThe floating deck features custom 2’x4’ porcelain tiles set on a pedestal system, allowing full water flow across the membrane.
- Composite Fascia & Custom RailingsPerimeter and stair fascia finished in Fiberon Earl Grey, paired with Century Scenic glass railings in front and Century pickets on the sides and stairs.
