Design & Engineering Process
From Concept to Completion: Our Floating Staircase Process
Structural Assessment & Design Consultation
Our structural engineers visit your site to assess the existing building structure and discuss your floating staircase vision. We evaluate load-bearing capacity, identify optimal anchor points, and develop preliminary designs that integrate with your architecture whilst achieving the dramatic floating effect.
Engineering & Building Approval
We prepare comprehensive structural calculations and detailed engineering drawings for building approval. Our designs include concealed support framework specifications, load transfer details, and compliance documentation. We coordinate with local authorities and building inspectors throughout the approval process.
Precision Fabrication & Framework Installation
The concealed steel support framework is fabricated and installed during your building’s construction phase. This critical stage requires precise coordination with other trades to ensure the framework is perfectly positioned and concealed within walls or structural elements before finishing work begins.
Custom Tread Manufacturing
Once the framework is in place, we fabricate your custom treads to exact specifications. Whether timber, steel, or glass, each tread is precision-manufactured to ensure perfect fit and alignment with the concealed support system.
Professional Installation & Commissioning
Our installation team fits the treads to the concealed framework, creating the dramatic floating effect. Final adjustments ensure perfect alignment, and comprehensive testing verifies structural integrity. We complete the project with detailed handover and maintenance guidance.
