Willen House

Location:
London.

Date:
July 2025.

Client:
Red Construction

Overview

Willen House has being transformed through major structural alterations, including portal frame floor additions, rear tower extensions, and additional levels. The scheme comprises self-contained bedrooms, alongside communal amenities such as sunken gardens, a lounge, a cinema room, a gym, and a yoga studio.

Working alongside the architect, RED Construction and Geostaff France, Fire and Smoke Solutions was brought in to deliver a compliant, low-impact solution within a tight programme for the mechanical smoke extract shafts.

Objectives

  • Replace several non compliant Shaft Wall Smoke Shafts with a Certified Solution.
  • Minimise disruption to surrounding works and live site operations.
  • Complete works on site within 8 weeks.

Challenges:

  • Limited riser space with competing services (electrical and mechanical).
  • Requirement for full compliance with EN 1366-8 and EN 13501-4.
  • Tight construction programme with limited access around shafts.
  • Sustainability targets set by the client requiring recyclable materials.

Our Solution

The FASS GEOTEC® smoke shaft system was specified and installed. GEOTEC® S45 boards were delivered flat-pack, pre-cut to size, and installed using the glue + screw GEOCOL® system. The self-supporting duct allowed installation from inside-out without the need for access all round, saving time and avoiding coordination clashes with other trades.

Our scope covered

  • Design and specification: Ensuring the system met project needs.
  • Procurement: Securing the required materials ahead of schedule to accelerate delivery.
  • Installation: Delivering the works safely and with minimal disruption to the existing site.

Key Outcomes

  • Design and Procurement ahead of schedule: Product secured and installed quicker than planned.
  • Fast installation: On-site works completed in just three weeks.
  • Fully compliant: System met all fire performance and regulatory requirements.

Result

  • Reduced installation time compared with builders work or plasterboard alternatives.
  • No additional site insulation required, saving labour and avoiding error risk.
  • Compact system allowed efficient use of risers, leaving space for other services.

Standards & Compliance Achieved:

  • Tested to EN 1366-8
  • Classified to EN 13501-4 (up to 1500Pa service pressure)
  • IFC Certified (SDI 19 & 20) for smoke shafts and ductwork
  • A1 non-combustible classification (EN 13501-1)
  • ETA 18/0343 – European Technical Assessment

Reviewing of Smoke Shaft Construction

Managing Director Ian Doncaster recently presented a Smoke Control Association document, reviewing smoke shaft construction and highlighting why only tested and certified systems should be installed.

It’s vital the industry moves away from untested methods and towards proven, standards-based solutions.

At FASS, we see the benefits every day with our GEOTEC® smoke shaft systems — tested to EN 1366-8 / EN 13501-4, IFC certified, and fully compliant from design through to commissioning.

Uno Golden Lane

Location:
London

Date:
March 2025

Client:
Migard

Overview

As part of a wider upgrade at a central London site, Migard needed to improve fire protection for a primary power supply route. The project required the over cladding of the existing cable trenches with an EI120 construction, with minimal disruption to ongoing site activity.

Working alongside the architect and Geostaff France, Fire and Smoke Solutions was brought in to deliver a compliant, low-impact solution within a tight programme.

Objectives

  • Increase the fire protection
  • Minimise disruption to surrounding works and live site operations
  • Complete works on site within 3 weeks

Our Solution

To meet the brief, we installed a Geotec Service Duct using Geostaff’s S45 board system – a proven solution for high-performance fire protection in service installation to BS EN 1366-8 and classified to BS EN 13501-5.

Our scope covered:

  • Design and specification: Ensuring the system met project needs
  • Procurement: Securing the required materials ahead of schedule to accelerate delivery
  • Installation: Delivering the works safely and with minimal disruption to the existing site

Key Outcomes

  • Design and Procurement ahead of schedule: Product secured and installed quicker than planned
  • Fast installation: On-site works completed in just two weeks
  • Fully compliant: System met all fire performance and regulatory requirements

Result

Project Uno was completed ahead of time and with no disruption to other site operations. The installed system delivered the required fire protection performance, and our team managed the process from start to finish – efficiently, safely, and in full compliance with standards.
