FREQUENTLY ASKED QUESTIONS
What is a Juliet Balcony?
A Juliet balcony is a guarding or barrier fitted across a full-height window or set of doors, allowing you to open them safely without the need for a projecting platform.
How do Juliet Balconies differ from full balconies?
Unlike a full balcony, a Juliet balcony does not project outward. It provides the appearance and benefits of a balcony – light, air, and safety, without needing extra floor space or planning for a structure
Do you need planning permission for a Juliet Balcony in the UK?
In most cases, planning permission is not required for a Juliet balcony. However, rules may apply if your home is in a listed building or conservation area. Always check with your local authority
Are Juliet Balconies compliant with UK Building Regulations?
Yes. Juliet balconies must comply with BS 6180 and other building regulations to ensure safety, including minimum guard heights and load resistance.
What height must the guard rail be on a Juliet Balcony?
In the UK, a Juliet balcony barrier must be at least 1,100mm (1.1m) high from the floor level, in line with building regulations.
What glass type is required in a glass Juliet Balcony?
Juliet balconies use toughened and laminated safety glass, designed to resist impact and provide long-term durability.
How thick should the glass be for safety in a Juliet Balcony?
The glass is typically 10mm–21.5mm thick, depending on design and span. Structural engineers determine the exact specification
What fixings are used to mount a Juliet Balcony to a wall?
Most Juliet balconies are fixed using engineered bolts or base-mounted brackets, which secure the structure safely to the wall or window frame. However, for extra-wide Juliet balconies exceeding standard spans, a bespoke structural steel frame may be required. These frames are channelled into the wall itself, ensuring the balcony is fully supported and compliant with structural safety standards.
Do Juliet Balconies increase the value of my home?
Yes. Juliet balconies improve natural light, enhance kerb appeal, and can increase the desirability and value of a property by up to 12%
How much do Juliet Balconies cost in the UK?
Costs vary depending on the size, design, and materials. A bespoke glass Juliet balcony designed, supplied, and installed can start from a couple of thousand pounds and increase substantially depending on span and bespoke structural requirements.
How long does installation take for a Juliet Balcony?
Juliet balconies can be installed within one to two days in most cases, with longer timeframes for larger projects involving structural steelwork or subframes.
What maintenance is required for Juliet Balconies?
Juliet balconies are low maintenance. Glass can be cleaned with non-abrasive solutions, and metal frames may require occasional cleaning to prevent dirt buildup.
Are Juliet Balconies safe in high wind or bad weather?
Yes. When installed with structural supports and tested glass and fixings, Juliet balconies are designed to resist wind loads and adverse weather conditions.
What is the difference between a Juliet Balcony and a Juliet Balcony with a small platform?
A standard Juliet balcony has no standing platform, while a Juliet balcony with a small projection extends out slightly to allow standing space. Platform designs may need additional permissions and engineering.
Can I retrofit a Juliet Balcony to my existing window or French doors?
Yes. Juliet balconies can often be retrofitted to existing openings, provided the wall structure is suitable for fixings.
Do Juliet Balconies require structural engineering reports?
Every Juliet balcony must be proven safe, not only in terms of glass performance but also wall composition and fixing strength. 360 GSS provides a structural engineer’s report covering both the glass and anchoring system to verify compliance and ensure safety.
