The Connoisseur’s Collection — By Appointment Only
An atelier service for landmark residences
Every opening. One atelier.
One standard — uncompromising.
From the Iconic Slim F80 bifold doors that dissolve the rear elevation into the gardens, to the bespoke aluminium entrance door at the front, the heritage sashes commanding the principal façade, the orangery roof above the morning room, the lantern rooflights pouring daylight onto the kitchen island, the switchable smart glass that veils the master ensuite at a touch, the integral blinds in the library, and the biometric lock that recognises the master of the house at the threshold — we specify, fabricate and install the entire glazing programme, as a single, choreographed commission.

Heritage windows in real period and conservation homes
Real UK installations of our astragal-bar heritage windows - Victorian terraces, Georgian town houses, Cotswold cottages and character new-builds. Shot on bright summer days so you can see the shadow the bars cast on the glass.
A single atelier, every opening
A residence of this calibre deserves a single specifier.
A distinguished renovation falters when six trades quote six disparate pieces of glass. Mismatched greys, mismatched guarantees, and nobody quite accountable when the rain finds its way in around the rooflight. The Connoisseur’s Collection resolves that by placing every opening in the residence within a single commission.

Aluminium bifold doors at the rear. Lift-and-slide sliding doors to the terrace. Bespoke aluminium or heritage sashes on the principal elevation. uPVC flush-sash on the coach house, garden room or ancillary annex. An aluminium front door with flush-mounted eKey dLine biometrics. Crittall-style glass doors between drawing room and snug. An orangery roof over the morning room. Slimline lantern rooflights above the kitchen island. A glass-box rear extension that draws the gardens inside. IoT switchable smart glass in the master ensuite. Integral blinds across the south-facing aspect. And the entire ensemble conversing with your Lutron, Crestron, Control4 or KNX system from the outset.

A more economical bifold option remains on offer for those who prefer it — the comparison further down articulates exactly what one gains, and foregoes, should thrift take precedence.
Why choose us

Biometric entrance — the residence that recognises you
Your fingerprint is the key — and the orchestra conductor.
A flush-mounted biometric reader is no longer simply a quieter way to unlock the front door. In a thoughtfully integrated residence, the touch of a finger at the threshold is also the cue for an entire choreography of lights, climate, blinds, intelligent glazing and even discreet voice announcement — tailored, individually, to the person who has just arrived home.
IoT switchable smart glass
Liquid-crystal (LC) and PDLC smart glass turns from crystal clear to opaque white in milliseconds. Specified as a sealed insulated glass unit (IGU) inside our aluminium frames — no retrofit film, no peeling, no compromise

Ensuite glass walls that frost at a tap Home-cinema partition glass clear by day, opaque for movies Office pods  private during calls, transparent otherwise Integrated with Lutron, Crestron, Control4, KNX and Apple Home Low-voltage 24 V AC, tiny < 5 W/m² power draw when on

Click the demo — that’s what it does in real time.
Integral blinds
Venetian or pleated blinds sealed between the two glass panes of the IGU. They never collect dust, never tangle, and survive the life of the glazing. Manual slider, electric or smart-home control Ideal for bifolds, rooflights and south-facing windows Aluminium slats in white, silver or bronze
eKey dLine biometric entry
Flush-mounted fingerprint reader recessed into the aluminium frame. Stores up to 99 unique prints, with remote locking and temporary-code access from your phone. Touch your finger  the house knows you’re home Integrates with Lutron, Crestron, Control4, KNX No more keys under the flowerpot
Acoustic glass
Asymmetric laminated glass dampens traffic, aircraft and conversation noise — essential for prestige homes near main roads, flight paths or town-centre locations. Up to 42 dB reduction Combines with solar-control and low-E coatings Same frame, same sightlines  just quieter
Solar-control glass
South-facing bifolds and orangery roofs overheat in summer. Solar-control coatings cut up to 65% of heat gain while keeping the view crystal clear. Specifiable on any of our IGUs Reduces air-con load significantly Pairs beautifully with integral blinds
Self-cleaning glass
Hydrophilic coating breaks down organic dirt in UV and washes it off in the rain. Specified on high, awkward-to-reach panels rooflights, gables and stair atria. Essential on 6 m lantern rooflights Reduces cleaning cycles dramatically Combines with solar-control for south aspects
Warm-edge triple glazing
Our triple-glazed IGU with warm-edge spacer bars delivers 0.8 W/m²K — Passivhaus territory — without sacrificing the slim sightlines. Argon or krypton cavity fill Low-E coatings on face 2 and 5 A+ rated WER
Biometric entrance — the residence that recognises you
The details that distinguish a prestige residence from a merely pleasant one.
A flush-mounted biometric reader is no longer simply a quieter way to unlock the front door. In a thoughtfully integrated residence, the touch of a finger at the threshold is also the cue for an entire choreography of lights, climate, blinds, intelligent glazing and even discreet voice announcement — tailored, individually, to the person who has just arrived home.
A small story, taken from life
“I’m popping outside for two minutes — I haven’t got my keys.”
Most readers will know the small irritation: stepping out to the bins, the post, the garden centre delivery, the dog — with no key in pocket and the front door determined to slam shut behind you. The household stratagem of wedging a stone, a shoe, a folded newspaper into the threshold is, of course, charming. It is also a freely advertised invitation to anyone passing on the pavement.

With biometric entry the story ends differently. One steps outside, allows the door to close fully and to lock as designed, and returns when ready. A touch of the finger at the reader, and one is home. No key. No stone. No nervous glance towards the gate. The residence is more secure, not less, precisely because one no longer has to leave it standing open.

A small change of habit — a measurable improvement in security, daily.
What the door does, instead:
Closes fully on its own door-closer. Engages all multi-point hooks & deadbolts. Reports the closure to one’s phone (silent, no notification storm). Logs the event in the audit trail. Awaits one’s return — and recognises one in under a second.
Biometric entrance — the residence that recognises you
Your fingerprint is the key — and the orchestra conductor.
A flush-mounted biometric reader is no longer simply a quieter way to unlock the front door. In a thoughtfully integrated residence, the touch of a finger at the threshold is also the cue for an entire choreography of lights, climate, blinds, intelligent glazing and even discreet voice announcement — tailored, individually, to the person who has just arrived home.
Personal scenes
Each finger, a different residence.
The master’s arrival raises the kitchen lighting to forty percent, sets climate to twenty-one degrees, opens the integral blinds in the principal rooms and queues a discreet jazz programme in the family room. The lady of the house has her own scene — classical playlist, scented candle scene on the smart switches, a low-warmth wash in the snug. The children unlock with their own prints to their own scenes — the parents’ private rooms remain locked. Each finger is, in effect, a different residence.
Discreet announcement
“Welcome home, James.”
A spoken welcome through one’s Sonos, Crestron or Control4 audio — addressed by name, in the room one is in. Useful in larger residences — the rest of the household knows who has come in without anyone having to call up the stair. The voice, the room, the volume and the wording are all configurable; mute the announcement entirely if one prefers silence.
Time-bound access
The cleaner. The dog walker. The gardener.
A staff print works only between, say, nine and one on Tuesday. A relative’s print is permitted weekends only. A holiday house-sitter receives access for a fortnight, after which their print is automatically retired. Every entry is recorded with name, time and (if specified) routed to one’s phone as an inconspicuous notification. The end of the keyhole-under-the-flowerpot era, decisively.
Climate & comfort
Each finger, a different residence.
Each profile carries its own climate set-point — nineteen for the master, twenty-two for the lady of the house, eighteen in the gym. Underfloor zones lift to the right temperature only in rooms that person is likely to occupy. Pair with the residence’s presence-detection logic and the heating bill is no larger for it.
Light, blinds, intelligent glass
The mood, prepared in advance.
Lights to one’s favoured scene; integral blinds to the angle one prefers; switchable smart glass set crystalline or opaque to taste. After dark, “arrive” raises the entrance lighting on the path and the porch, sets the stair-light low, and never floods the bedroom landing — a gentle homecoming, never a stadium.
Remote command
Open the door from anywhere.
A single tap on the mobile app unlocks the residence from anywhere with a data signal  the airport, the office, abroad on holiday. Useful for letting a courier into the porch, a contractor into the workshop, a relative into the kitchen door whilst one is travelling. Connection encrypted end-to-end via the Microsoft Azure cloud; one’s biometric data never leaves the device.
Audit reports
A full ledger of comings and goings.
A tidy log of every entry — who, when, by which entrance, whether by finger, app or override. Export weekly or monthly to PDF for one’s records, the household manager, or in the unhappy event of an incident, for the police or the insurer.
Sovereign cloud, no subscription
Microsoft Azure. No monthly fee. Ever.
The mobile application is provided without subscription — one’s commission includes lifetime access for as many users as one wishes. Cloud infrastructure runs upon Microsoft Azure UK and EU regions. Encrypted at rest, encrypted in transit, GDPR-aligned, and engineered against the casual ransomware now plaguing certain consumer smart-lock platforms.
Integration platforms
Lutron, Crestron, Control4, KNX, Apple Home.
Every modern home-automation platform is supported via API, contact closure, KNX bus or HomeKit accessory. One’s integrator receives the technical pack alongside the elevation drawings, so commissioning is a matter of an afternoon, not a week.
Real photography
Recessed in the frame, set into the brick, or built into the handle.
Slim 80 mm frames, triple interlock gaskets, huge glass panels - engineered for UK builds, tested for UK weather. Photography from recent installs.
Option 1 · In the frame
Recessed flush in the aluminium
The most-specified mount — invisible until lit, set into the door stile beside the handle. Reads in well under a second, even in driving rain.
Option 2 · In the wall
Set into the brick or stone
For listed properties, heritage front doors and where the architect prefers the reader entirely separate from the joinery. Recessed within a single course of brick or set into the stone reveal.
Option 3 · In the handle
Within the door pull-handle
A single sculptural element — the hand falls naturally upon it, the print is read as one grasps the door. Particularly considered for very tall single-leaf entrance doors with a full-height pull.
In summary — what is, candidly, included.
Up to ninety-nine prints per residence; per-person scene, climate, lighting, blinds and smart-glass macros; voice announcement on entry (configurable, optional); time-bound and day-of-week access for staff and visitors; full audit log with PDF export; remote unlock from anywhere via the mobile app; UK / EU Microsoft Azure cloud; no subscription, ever; lifetime updates; and integration with Lutron, Crestron, Control4, KNX, Apple Home and the major audio platforms.

The process, attended to
From first conversation to final polish — discreetly.

Private consultation
A senior specifier shall be in touch within one working day. We listen attentively, and counsel only thereafter.
2
Site visit & survey
A complimentary visit anywhere within the United Kingdom. Every opening measured, integrations discussed, the physical sample case presented in person.
3
Elevation drawings
Scaled drawings with sightlines, mullions, threshold details and an NBS-format specification for one’s architect of record.
4
Fixed-price proposal
Line-by-line across the entire commission. Both bifold options priced in parallel, that the decision may be made without ambiguity.
5
Fabrication
Manufactured in the United Kingdom to one’s precise colour, glass and ironmongery specification — four to fourteen weeks, in keeping with the scope.
6
Installation & sign-off
Our senior installation team attend every opening and depart leaving no trace. The ten-year guarantee is issued upon completion.
Remarked upon
Specified by architects, chosen by the discerning.
“One supplier for every opening in the house — bifolds, heritage sashes, rooflights, the biometric front door. No trade coordination drama and one guarantee to keep filed. It’s the way prestige residential should be done.”
James R.
Main contractor, Oxfordshire
“We chose GWS because they understood "close enough" wasn’t going to cut it. The fingerprint entrance, Crestron integration and the switchable glass in our ensuite are now my favourite details in the whole build.”
Priya & Tom D.
Homeowners, Cotswolds
“Drawings in 24 hours, fixed-price quote at the end of week one, on site week six — for every opening on a £2.4m restoration. That is not how our trade normally runs. It is how this one should.”
Alex H.
Homeowner, Harborne
Frequently asked
Prestige whole-home glazing — FAQs
Do you furnish the entire residence as a single commission?
Indeed — that is precisely how the Connoisseur’s Collection is intended to be specified. Aluminium and uPVC windows, bifolds, sliding doors, entrance and internal doors, conservatory roofs, rooflights and rear extensions are all provided under one proposal, one programme of works and one ten-year guarantee.
What, in essence, is switchable smart glass?
A liquid-crystal (LC / PDLC) glazing that resolves from crystalline to opaque at the touch of a finger. We specify it as a sealed insulated unit within our aluminium frames — no retrofit film, no peeling, no compromise. It speaks fluently to Lutron, Crestron, Control4, KNX and Apple Home.
What is the eKey dLine?
A flush-mounted fingerprint reader recessed into the aluminium frame. Ninety-nine prints stored, silent recognition, remote management, and gracefully integrated with one’s home-automation platform of choice.
Are integral blinds a worthwhile refinement?
Decidedly so. Sealed between the two panes of the insulated unit, they collect neither dust nor stray hairs, never tangle, and accept manual, motorised or smart-home control. Particularly considered on south-facing bifolds and lantern rooflights.
Do you work alongside architects and principal contractors?
Regularly. We furnish NBS-format specifications, elevation drawings, U-value calculations and Part L compliance documentation. Supply-only terms are available to the trade upon application.
What lead times might one expect?
Bifolds and windows: four to six weeks. Conservatory roofs: six to eight weeks. Glass-box rear extensions: ten to fourteen weeks. A priority service is available to compress the glazing element to two or three weeks where the schedule demands it.
