Why Floating Stairs Are Gaining Popularity in Seattle Homes

In recent years, floating staircases have become a hallmark of modern Seattle architecture — gracing everything from Lake Washington waterfront homes to industrial lofts in Ballard and Queen Anne. Homeowners love their open, airy look and the way they make even compact spaces feel larger and brighter.

Unlike traditional framed stairs, metal floating stairs use hidden supports and a minimal structure to create a clean, sculptural effect.

If you’re planning a remodel or building a custom home, this guide will walk you through everything you need to know to choose the right metal floating staircase, from structure types to materials and budget expectations.

Plan for Your Space and Layout

Before selecting a stair design, consider how it fits your home’s layout and ceiling height. Floating stairs are typically best for open floor plans, entryways with natural light, or multi-level lofts where you want to maintain visual flow between levels.

• Small spaces – A mono-stringer staircase (single center beam) saves space while maintaining strength.
• Large open areas – A double-stringer or side-mounted stair provides symmetry and balance for wide staircases.
• Tight turns or corners – A curved or L-shaped floating stair works best to add movement while fitting within confined footprints.

Open Risers vs. Closed Risers

A major design choice for floating stairs is whether to go with open risers or closed risers.

• Open risers create a sense of lightness and transparency — perfect for modern or minimalist interiors. They allow natural light to pass through and highlight the craftsmanship of the metalwork.
• Closed risers offer a more traditional and solid look, sometimes preferred for safety or if you want to minimize visibility between floors.

In Seattle, open-riser designs are especially popular in homes that feature glass railings, high ceilings, and large windows — as they visually connect spaces while preserving a modern aesthetic.

Choosing the Right Metal Structure: Single Stringer or Dual Stringer

The stringer is the structural backbone of any floating staircase. For metal stairs, we offer two main configurations, each offering a distinct aesthetic and engineering advantage.

Single (Mono) Stringer

A single beam runs under the treads, usually centered. This design delivers a clean, sculptural appearance and maximizes open space. It’s one of the most popular options in contemporary Seattle homes.

Two parallel beams provide extra support and rigidity — a great choice for wider stairs or commercial settings. This style also works well with heavier tread materials like thick wood or stone.

Tread & Handrail Materials: Mixing Metal, Wood, and Glass

Your tread and railing selections define the overall look and feel of your floating stairs. The most stunning designs often combine materials — metal for structure, and natural or transparent materials for warmth and light.

Handrail & Infill Options:

• Glass Railings – Offer seamless visibility, ideal for view homes or daylight-filled interiors.
• Cable Railings – Add a sleek, horizontal element and maintain openness.
• Metal Pickets or Flat Bars – Provide strong geometric rhythm for modern design styles.
• Wood-Capped Rails – Combine natural texture with the strength of metal.

When choosing finishes, consider matte black powder coat for a timeless architectural look, or brushed stainless steel for a brighter, refined aesthetic.

Match Your Home’s Style: Modern, Industrial, or Scandinavian

Seattle’s residential architecture is diverse — from mid-century modern homes in Shoreline to new Scandinavian-style builds in Ballard. Your stair design should align with your home’s architecture.

• Modern Homes: Choose slim, linear stringers with glass or cable infill for a minimalistic look.
• Industrial Lofts: Exposed metal beams, welded joints, and darker finishes fit the urban vibe.
• Scandinavian Style: Pair powder-coated white or light gray steel with light oak treads for a bright, airy aesthetic.

Working with a custom fabricator ensures every detail — proportions, finishes, and connections — harmonizes with your space.
