L-shaped and U-shaped stairs work well when deck height or lot space limits a straight stair run. Adding landings makes your stairs safer and keeps traffic moving smoothly.
These shapes also cut down on bulky looks and spread weight evenly, helping your deck stay stable over time.
Best suited for:
Taller decks
Side-yard or corner access
Layouts requiring directional changes
Floating and Open-Riser Stairs
Floating and open-riser stairs are perfect for modern decks that need a light and airy feel. Removing closed risers lets sunlight and air pass through, so your deck doesn’t feel boxed in.
Open-riser stairs need careful spacing and tread depth to stay safe, but they keep your deck looking sleek and modern.
Best suited for:
Contemporary deck designs
Homes with strong sightline priorities
Projects emphasizing architectural detail
Spiral and Curved Stairs
Spiral and curved wooden stairs shine when you want both style and space-saving. These stairs give access to elevated decks without eating up too much yard space.
