Every installation meets the Part K guarding rules at 1100mm, with a free survey and quote and a 24/7 line on 07399 253464.
A Juliet balcony is a guarding barrier fixed across a full-height opening, so a bedroom or first-floor living room can have French doors that open fully to fresh air with no projecting platform outside. In a London terrace it is often the single biggest improvement you can make to a first-floor room: floor-to-ceiling light, cross-ventilation in summer, and a view down the street instead of a windowsill. Because nothing projects beyond the face of the building, most houses can add one without planning permission, and there is no structural balcony to design, waterproof or maintain.
A single panel of toughened laminated glass held by discreet stainless steel fixings into the reveals either side of the opening. From inside the room there is almost nothing to see, which is the point.
13.5mm to 17.5mm toughened laminated · openings up to about 3m · the cleanest look
The glass sits in a slim aluminium channel fixed across the face of the building below the door threshold. No side fixings needed, so it suits wider openings and walls with shallow reveals.
17.5mm toughened laminated · wider spans · channel colour-matched to the doors
A powder-coated aluminium top rail with glass or vertical bar infill. More traditional in feel, the most economical option, and easy to match to anthracite or heritage-coloured doors.
10mm toughened or laminated infill · any RAL colour · fastest to install
Because the doors open above ground level, Building Regulations Part K treats a Juliet balcony as guarding, exactly like a balustrade on a terrace. That means real numbers, not taste:
Most Juliet balcony projects start as a window: a first-floor opening that deserves to become full-height glass. We handle the whole job, enlarging the opening where needed, fitting uPVC French doors or slimmer aluminium French doors made by our sister factory, then installing the guarding, so the doors and balcony arrive engineered as one assembly rather than bolted together by two trades. Door installations are FENSA certified, and the balcony fixings are set out around the new frame from day one. Already have sound French doors? We fit to existing openings just as happily, and if you are weighing up a walk-out platform instead, our glass balustrades page covers terraces and full balconies.
