What is a Juliet Balcony?
A Juliet balcony is a safety railing installed at upper-floor doors or full-height windows. It protects the opening without projecting from the building—the key difference from a traditional balcony, which extends outward and provides a floor to stand on.
Building Regulations Compliance
A Juliet balcony allows you to install full-height French doors on upper floors whilst meeting Building Regulations. You can open the doors to enjoy natural light, ventilation, and views, but you cannot step out onto a platform.
Perfect for Loft Conversions
Increasingly popular across Swansea for loft conversions and bedroom extensions, they transform attic spaces by creating openness whilst adding architectural appeal.
No Planning Permission Required
Because they don’t project beyond your building’s facade, Juliet balconies typically require no planning permission. These systems are also called French balconies or balconettes in the UK.

Juliet Balconies We Install in Swansea
Swansea Glass Balustrades installs three main types of Juliet balcony systems across Swansea and Gower.
Frameless Glass Juliet Balconies
Our most popular system. Frameless glass Juliet balconies use 21.5mm laminated toughened safety glass with minimal aluminium side fixings—no handrail, just pure architectural glass.
This creates completely unobstructed views, perfect for coastal properties overlooking Rhossili Bay—voted one of the top 50 beaches worldwide—and Three Cliffs Bay, named best UK beach by the BBC. The frameless design preserves these panoramic coastal outlooks whilst providing full fall protection.
Ideal for contemporary homes, modern loft conversions, and the 2,000+ apartments across SA1’s Marina development where floor-to-ceiling glass and open-plan living define the architectural aesthetic.
Glass Juliet Balconies with Aluminium Handrails
Glass panels (10mm toughened) combined with an elegant aluminium top rail. This system balances transparency with a traditional handrail for added reassurance.
The handrail provides a tactile grip point preferred by many homeowners, particularly for bedrooms where family members of all ages will use the doors. Available finishes: brushed silver, anthracite grey RAL 7016, or black RAL 9005. Popular throughout Sketty, Uplands, and West Cross for period property extensions.
Traditional Metal Juliet Balconies
Stainless steel or powder-coated aluminium construction. Metal Juliet balconies suit period properties across Swansea and Gower.
Particularly appropriate for Victorian terraces dating from the 1890s in Uplands with their characteristic Italianate architectural details, the mix of Victorian and Edwardian two and three-storey terraces throughout Mumbles and Newton Road, and traditional Welsh stone cottages across the Gower Peninsula.
We offer various designs from simple vertical bars to decorative patterns that complement your property’s architectural character. Powder-coated finishes available in any RAL colour. Black remains the most popular choice for period properties.

Juliet Balconies For Swansea Loft Conversions & Extensions
Juliet balconies are the ideal solution for loft conversions across Swansea—particularly popular in Sketty, Uplands, and West Cross.
Transform Your Loft Space
Adding full-height French doors with a Juliet balcony transforms a cramped attic into a light-filled bedroom or home office. This is especially valuable where ceiling height is limited.
Building Control Requirement
When you install doors at height, Building Regulations require fall protection. A Juliet balcony provides compliant safety whilst maximizing light.
Coordination with Your Builder
Swansea Glass Balustrades works alongside your loft conversion specialist or builder. We ensure the structural opening is correctly sized, provide load-bearing calculations, and coordinate installation timing with your project schedule.
Frameless Glass Systems Work Best
For loft spaces, frameless glass Juliet balconies maximize the perceived ceiling height without visually obstructing the room. The transparency makes small converted spaces feel larger.
Also ideal for bedroom extensions, kitchen extensions with mezzanines, and any upper-floor addition requiring French doors.

Coastal-Specification Balconies for Mumbles & Gower
Properties in Mumbles, Langland Bay, Caswell Bay, and across the Gower Peninsula face unique challenges from Swansea Bay’s coastal environment. Salt air, driving rain, and strong winds require specific material specifications.
Marine-Grade Stainless Steel Fixings
Standard stainless steel fixings corrode rapidly in coastal locations. Within months, rust staining appears. Swansea Glass Balustrades specifies 316 marine-grade stainless steel as standard for all Mumbles and Gower installations. This grade resists corrosion from salt air exposure—essential for properties from Mumbles Head through to Port Eynon and Rhossili.
Wind Load Calculations
Exposed coastal locations require proper structural assessment. We conduct wind load calculations for properties facing Swansea Bay or situated on elevated Gower positions.
Glass Performs Better Than Metal
Frameless glass Juliet balconies are particularly popular on coastal properties. Glass doesn’t corrode, requires no painting, and preserves the sweeping views across Blue Flag beaches like Langland and Caswell that make these locations so desirable. We use the same coastal-grade glass for our deck balustrade installations across Swansea.
Call 01792940898 for coastal-specification balconies.
Building Regulations & Planning Permission in Swansea
All Juliet balcony installations must comply with BS 6180:2011—the British Standard for protective barriers in buildings.
Building Regulations Compliance
Key requirements:
- Minimum height: 1100mm from floor level
- Load capacity: 0.74 kN/m horizontal load for domestic properties
- Glass specification: Toughened and laminated safety glass to BS 6206

Exceptions: listed buildings (Swansea has over 500), properties in conservation areas (Swansea has 31 designated conservation areas including Mumbles Conservation Area), and flats requiring freeholder permission.
Working within Gower—the UK’s first Area of Outstanding Natural Beauty, designated in 1956—we understand the heightened sensitivity around architectural alterations and design appropriateness.
