Stair Treads & Fireplace Mantles
Architectural Timber. Built Beyond Furniture.
Architectural Timber. Built Beyond Furniture.
Floating stair treads, fireplace mantles, and structural timber features require more than beautiful wood — they demand stability, precision craftsmanship, and carefully selected slabs built to perform in architectural environments.
JJN Timbers specialises in handcrafted solid timber stair treads and live-edge mantles designed for modern homes, luxury lodges, hospitality spaces, and architectural interiors.
From refined minimalist builds to rugged natural live-edge installations, every piece is individually selected and handcrafted in our Johannesburg workshop.

Crafted for Architects, Designers & Feature Spaces.
Our floating stair treads are produced from carefully selected hardwood slabs chosen for structural integrity, grain consistency, and long-term durability.
Available in a range of African hardwoods including Blackwood, Beefwood, Brown Poplar, Sand Kiaat, Leadwood, Gum, and Wild Olive.
We offer both refined modern profiles and natural live-edge finishes depending on the desired architectural style.
Mantles are available in minimalist contemporary finishes or more rugged feature-grade slabs with dramatic grain movement, natural cracking, and organic edge detail.

Rare Capability. Genuine Craftsmanship.
Very few workshops in South Africa work comfortably at this scale with solid hardwood slabs.
From oversized milling and slab preparation to sanding, stabilising, sealing, and finishing, JJN combines sawmill capability with furniture-grade craftsmanship to create architectural timber pieces built to last for generations.
From Raw Slabs to Architectural Features.
