Luxury Contemporary Home in Guernsey: A Complete Architectural Glazing Package
Azure Outdoor Living designed, supplied and installed the complete aluminium glazing package for an architect-designed luxury residence in Guernsey, working alongside principal contractor MLL Construction and Channel Islands delivery partner Bonsai Group. The package combined Origin windows and doors, Cortizo Cor Vision minimal sliding doors and four bespoke bonded aluminium rooflights, finished throughout in Jet Black (RAL 9005 matt) with a marine grade powder coating suited to the coastal environment.
Project at a Glance
- Location: Guernsey, Channel Islands
- Principal contractor: MLL Construction
- Channel Islands delivery partner: Bonsai Group
- Glazing package: 9 Origin OW-80 aluminium windows, 2 Origin residential entrance doors, 5 Cortizo Cor Vision minimal sliding doors with 20mm interlocks, 4 bespoke bonded aluminium rooflights
- Finish: Jet Black (RAL 9005 matt), marine grade powder coating
- Azure’s role: technical specification, precision laser surveying, CAD manufacturing drawings, structural opening coordination, logistics to Guernsey, specialist installation, commissioning and aftercare
The brief
The ambition was to redefine how the building related to light, space and its landscaped gardens: expansive openings in every main living space, flush thresholds flowing from internal floors to external terraces, minimal aluminium sightlines and rooflights bringing daylight into the centre of the plan.
Achieving that meant treating glazing as part of the structure rather than a finishing trade. Structural steelwork, opening sizes, finished floor levels, drainage and threshold details were all engineered around the glazing, so Azure was involved from the construction phase onwards rather than at fit-out.
The Four Challenges That Defined the Project
- Millimetre tolerances. The Cortizo Cor Vision system achieves its minimal appearance with 20mm vertical interlocks, which leaves almost no margin for error. An opening only a few millimetres outside tolerance affects frame alignment, sliding operation, drainage and visual symmetry.
- Panel weight. The largest Cortizo panels weighed in the region of 300kg. Glass at that scale cannot be manhandled, so lifting positions, access routes and the installation sequence were engineered before manufacture, with a HIAB crane, vacuum lifting attachment and a specialist glazing robot doing the work on site.
- Island logistics. Every unit crossed to Guernsey by ferry in purpose-built transport stillages, with freight, crossings and site deliveries timed against the construction programme. There is no popping back to the depot for a forgotten fixing; every tool, seal and spare travelled with the team.
- A coastal environment. Salt air is unforgiving to standard finishes. The entire package was specified in marine grade powder coating so the Jet Black finish holds its depth against exposure, without compromising the slim profiles the architecture depends on.
Precision Before Manufacture
For minimal-frame systems, accuracy is decided long before installation. Azure surveyed every opening using Leica DISTO laser measurement and Hilti rotary laser levels, cross-checking each dimension before CAD manufacturing drawings were released. Structural openings, steel positions, finished floor levels, drainage and thresholds were coordinated with MLL Construction so the glazing arrived to fit the building, and the building was ready to receive the glazing.
The Channel Islands Dimension
Working in Guernsey brings its own rules, and on this project they worked in the client’s favour. The glazing package was invoiced without VAT as a zero-rated UK export, and Guernsey currently applies no VAT or GST of its own, a substantial saving against the same package supplied to a mainland address. Tax treatment always depends on the specifics of a project, so confirm your own position with your adviser.
The export and customs paperwork was handled by Azure with the assistance of island partner Bonsai Group, whose local knowledge takes the friction out of Channel Islands delivery. Freight sailed from Portsmouth, roughly a day’s crossing, timed against the build programme. Guernsey’s own Building Regulations and Guernsey Technical Standards applied rather than UK Approved Documents, with MLL Construction as principal contractor liaising directly with the States of Guernsey Building Control service while Azure supplied the specifications, U-values and glazing evidence their submissions required.
Frequently Asked Questions
Why involve a glazing specialist during the construction phase?
Because structural openings, steel positions, finished floor levels, drainage and thresholds all have to be engineered around the glazing. Early involvement means those details are resolved before concrete is poured, which avoids costly remedial work and protects the architect’s sightlines.
How is oversized architectural glazing installed?
Panels in the 300kg range are offloaded by crane with vacuum lifting attachments and positioned using a glazing robot. Manual handling is not an option at this scale, so lifting positions, access routes and installation sequence are all planned before the glass arrives.
Can bespoke architectural glazing be delivered to the Channel Islands?
Yes. On this project every unit travelled from mainland Britain in purpose-built transport stillages, with freight, ferry crossings and site deliveries timed against the construction programme. Azure manages Channel Islands logistics as part of the glazing package.
Do UK building regulations apply in Guernsey?
No. Guernsey has its own Building Regulations and Guernsey Technical Standards, administered by the States of Guernsey Building Control service. UK Approved Documents and self-certification schemes such as FENSA do not apply, although the standards are broadly aligned with modern UK practice.
Is VAT charged on glazing supplied to Guernsey?
Goods exported from the UK to the Channel Islands can be zero-rated for UK VAT where evidence of export is held, and Guernsey currently has no VAT or GST of its own. On this project the client was invoiced VAT-free on exactly that basis. Tax treatment depends on the specifics of each project, so always confirm your position with your own adviser.
How accurate does a glazing survey need to be?
For minimal-frame systems such as Cortizo Cor Vision, tolerances are measured in millimetres. Azure uses Leica DISTO laser measurement and Hilti rotary laser levels, and cross-checks every dimension before manufacturing drawings are released.
What glazing suits coastal properties?
Marine grade powder-coated aluminium. It resists salt-air corrosion and weathering while holding the slim contemporary profiles that minimal-frame architecture depends on.
Planning an Architectural Glazing Project?
Whether you are building a contemporary new home, extending an existing property or delivering a high-end residential development, on the mainland or in the Channel Islands, involving your glazing specialist early makes a measurable difference to the finished result and the efficiency of the build. Azure Outdoor Living works with homeowners, architects, developers and principal contractors to deliver complete aluminium glazing packages, from first design discussions and precision surveying through to CAD drawings, specialist logistics, installation and aftercare.
