Two balconies wear the same name — and need very different specifications.

The word "balcony" gets used for two completely different builds. A Juliet balcony is a decorative balustrade fixed in front of a French door or a full-height window — it provides fall protection, it lets light and air through the opening, and it carries nothing more than its own weight. A structural balcony is a real platform you can stand on, typically cantilevered out from the building's floor plate or supported on brackets and posts, and it is a serious structural element of the building. Same word, two very different conversations with two very different drawings.

Confuse the two at quote stage and the project goes sideways fast. Spec a structural balcony from a balustrade fabricator's price list and you'll be left short of brackets, fixings, deflection limits, and Building Control sign-off. Spec a Juliet balcony to structural drawings and you'll spend money you didn't need to spend. The pricing, the planning route, the engineering input and the install sequence are all different — they only converge at the welding.

Our job is to be honest about the two early. If your project is a Juliet balcony for a period property's first-floor sash window, we'll quote the balustrade, the fixings into the masonry, and the heritage-sympathetic finish — and your conservation officer will sign it off. If your project is a fourth-floor structural balcony off a new-build apartment, we'll work to your structural engineer's drawings, fabricate the steelwork, and install to the spec they've signed.

What We Fabricate

Bespoke balcony fabrication across the full residential and commercial spectrum — from a single decorative Juliet for a Yorkshire townhouse to a run of structural balconies for a new-build apartment scheme. Every piece is made to measure in our Leeds workshop, finished to the agreed specification, and installed by the same team that fabricated it.

Traditional ornamental Juliet balconies

Hand-fabricated wrought-iron-style Juliet balconies for period properties, conservation areas and listed buildings. Scrollwork, fleur-de-lis detail, twisted bar work and ring-and-collar joints in the heritage tradition — sympathetic to the building's age, properly proportioned to the opening, and finished in matt black or hand-painted to match existing ironwork. We're happy to copy detail from a surviving original elsewhere on the building. See our traditional wrought iron fabrication page for the full ornamental range.

Modern glass-and-steel Juliet balconies

Contemporary Juliet balconies pairing a minimal steel frame with frameless toughened glass infill. Side-fix to masonry returns or top-and-bottom fix into the reveal — the fixing strategy depends on the wall build-up and what's behind the render. The glass specification (toughened, laminated, heat-soaked) follows BS 6180 and the relevant glazing standards; we'll work to the specification your architect or glazing consultant has confirmed.

Structural cantilever balconies

Steel cantilever balconies where the structural balcony plate is anchored back into the building's floor structure and projects clear of the facade with no external posts or columns. The cantilever moment, fixings into the slab or steel frame, thermal break detail and deflection limit are all designed by your structural engineer — we fabricate to the drawings, drill and weld to tolerance, and install to the sequence the engineer has signed. Decking, soffit detail and balustrade are coordinated as part of the package.

Structural supported balconies

Balconies that are carried on external posts, perimeter columns or hangers from above — typically more economical than a true cantilever and often the right answer for retrofit work or larger projecting platforms. Post-supported balconies require careful coordination with the structural engineer over base-plate fixings, post-to-balcony connections and lateral bracing. We fabricate the steel frame, weld and bolt to spec, and install the balustrade and decking as the package requires.

Glass balustrade integration

Frameless or post-and-rail glass balustrades fitted to existing balconies, terraces and roof gardens — see our balustrade fabrication page for the full range. For balcony work specifically, we typically combine a steel top rail or steel posts with toughened glass infill panels. Top-fixed or side-fixed depending on the substrate. Designed and fabricated in accordance with BS 6180.

Finishes

Hot-dip galvanising and powder coating in any RAL colour for modern installations; wet-painted finishes (typically matt black) for heritage and conservation work; stainless steel for coastal or pollution-heavy sites where rust protection matters more than visual warmth. Decking options include open-grid steel, hardwood, composite, or porcelain tile on pedestal — coordinated with the structural engineer's loading allowance.

Standards: Designed and fabricated in accordance with BS 6180. Welded by coded operatives certified to BS EN ISO 9606. Fabrication tested to BS 4872.

Structural disclaimer. All metalwork is fabricated to the specifications provided by the client's structural engineer or architect. Final compliance with Building Regulations is subject to the overall building design and is confirmed through Building Control approval. Structural balconies are designed by your structural engineer. We fabricate the steel to their drawings and install to spec — final compliance with Building Regulations is subject to Building Control approval.

How We Work

Frequently Asked Questions

What's the difference between a Juliet balcony and a structural balcony?

A Juliet balcony is a decorative balustrade fixed across a French door or full-height window opening — there's no platform to stand on. It provides fall protection, and it carries its own weight only. A structural balcony is a real projecting platform with a steel frame, decking and balustrade — typically cantilevered from the building structure or supported on posts. Structural balconies require structural engineer sign-off and Building Control approval. Juliet balconies usually don't.

Do I need planning permission for a balcony?

It depends on the type. A Juliet balcony that doesn't project from the facade — purely a balustrade in front of an existing opening — is often treated as permitted development on a typical dwelling. A structural balcony that projects from the building, alters the external appearance, or overlooks neighbouring property usually does require planning permission. Listed buildings, conservation areas and flats almost always require approval. We'll flag the likely planning route at site survey, but the final decision sits with your local planning authority.

Do you need Building Control sign-off?

For a Juliet balcony — usually just the balustrade itself needs to meet BS 6180 (1100mm minimum height above the finished floor level for residential above ground level, infill spacing limits, horizontal line load resistance). For a structural balcony, yes — the structural design, fixings, deflection limits and connections all sit under Building Regulations Part A and require Building Control approval. The structural engineer's calculations are signed off as part of the build. We fabricate to those drawings; Building Control sign off the overall installation.

What is BS 6180 and how does it apply?

BS 6180 is the British Standard for "Barriers in and about buildings" — it sets the minimum heights, the maximum gaps in infill (typically 100mm so a 100mm sphere cannot pass), and the horizontal line and uniformly-distributed loads that a balcony balustrade must resist. For residential balconies above ground level the minimum height is 1100mm. For non-residential the requirements vary. Every balcony balustrade we fabricate is designed and fabricated in accordance with BS 6180.

Glass infill or metal infill — which is right?

Glass gives an unobstructed view and a clean contemporary look — good for new-builds, balcony platforms with a view worth seeing, and modern townhouse Juliets. Metal infill (vertical bars, decorative scrollwork, perforated panels) suits heritage and conservation work, traditional terraces, and any installation where privacy matters more than the view. Glass is more expensive upfront and requires periodic cleaning to look right. Metal is more forgiving over time and easier to repair if damaged. Both are designed to BS 6180.

Can you match a Juliet balcony to an existing one on a period property?

Yes. Listed buildings and conservation areas typically require new ironwork to be sympathetic — sometimes copy-detail — to surviving originals on the same building or in the same terrace. We're happy to take dimensions and detail photos from an existing Juliet, replicate the scrollwork or bar profile, and fabricate a matching unit. Conservation officers often want to see a fabrication sample or a CAD drawing before approval. We'll provide both as part of the quote.

Can you fabricate balconies for a listed building?

Yes, regularly. Listed Building Consent is a separate process from standard planning permission and is handled through your local authority's conservation officer. We can fabricate to the detail and finish the conservation officer signs off — typically matt black wet paint over an oxide primer, hand-forged scrollwork where the original has it, and resin-anchor fixings that avoid damaging original masonry. We'll attend a site meeting with your architect or conservation officer if it helps the application along.

How does a balcony integrate with the existing facade?

For Juliet balconies the fixings are typically resin-anchored into the masonry reveal each side of the door opening, or top-and-bottom into the lintel and the floor structure. We agree the fixing strategy after a site survey — what's behind the render or brickwork dictates the answer. For structural balconies the integration sits at design stage with your structural engineer — typically a thermal break detail (Schöck, Halfen or similar) between the external steel and the internal floor structure, or back-fixings into a steel-framed wall. Either way, we coordinate with the engineer's drawings.

What's the typical lead time?

From signed quote to delivered balcony is typically four to six weeks for a single Juliet, and six to ten weeks for a structural balcony where engineer drawings are needed. Site survey takes a few days to schedule, CAD drawings and a written quote follow in around three working days. For new-build schemes with multiple units we agree a delivery and install schedule with the main contractor at the start, and phase the work to suit the build programme. All quotes are subject to site survey, and typical lead times are subject to project complexity.
