Project Portfolio: Semi-Circular Glass Floor Hatch [SW18 Wandsworth]

Project Overview

• System: Bespoke Semi-Circular Hinged Glass Door

• Location: Wandsworth, London (SW18)

• Application: Spiral Wine Cellar Access

• Service: Full Design, Manufacture, and Installation by Dio-Met

The Challenge: Seamless Integration in South West London

For this residential project in the SW18 district of London, the client faced a common architectural dilemma: a traditional spiral cellar with a concrete semi-circular opening that felt out of place in a modern kitchen. Dio-Met was commissioned not only to manufacture but also to professionally install a sleek, structural glass floor hatch that reveals the cellar as a high-end feature.

• Precision Frame Engineering: We fabricated a rectangular steel frame designed to fit exactly into the Wandsworth property’s existing floor recess, providing a robust structural base.

• The "Invisible" Arc: Using our proprietary glass painting technique, we followed the exact semi-circular arc of the spiral stairs. This conceals the concrete sub-structure, offering a clean, sophisticated look synonymous with London’s luxury interior design standards.

• Effortless South London Luxury: Despite the heavy 25.5mm laminated glass, the system operates with "floating" ease thanks to our factory-calibrated gas struts. 

• Professional Dio-Met Installation: By choosing our in-house installation team, the client ensured that the structural glass was perfectly leveled and the gas-strut tension was fine-tuned on-site for optimal performance.

Technical Expert Insight: Structural Solutions for Wandsworth Basements

In high-value London postcodes like SW18, floor space is at a premium. Engineering a semi-circular hatch requires a deep understanding of load distribution; unlike a standard square door, the glass weight is offset across the hinge axis. Our solution utilizes a structural ring-beam frame that prevents any "twisting" or frame deflection, ensuring the unit remains perfectly flush with the kitchen floor. By providing a full supply and installation service, we take total responsibility for the structural integrity and the UKCA-certified safety of the unit, ensuring it meets all residential load-bearing standards while showcasing the collection below.
