Every figure below comes from a completed project on this page. They are the numbers a main contractor or developer actually needs when deciding whether a steel frame specialist can handle their scheme.
We work across SFS infill, stick-build full builds and panellised full builds, for main contractors, developers, local authorities and universities — in London, the South East and across the UK.

Infill is the largest part of our portfolio. These are non-load-bearing walls of cold-formed steel fixed between the floors of a concrete or hot rolled steel frame — carrying cladding, sheathing and wind load, but not the building’s weight.
The projects below run from a 120-minute fire-rated façade at the former Fulham Gas Depot for Erith, to a 14-storey mixed-use tower in west London built with no site storage at all, to an acoustic wall of 18-metre studs separating offices from military weapons storage in Bolton.

BAS Frames designed, supplied and installed the SFS infill package for a six-storey development at 159 High Street, Harrow, for an overseas developer running their first UK project — delivered ahead of the agreed programme, and followed by an invitation to take on further packages on the same scheme. The client was Greenvista Developments. The […]
BAS Frames installed over 2,000m2 of SFS and external boarding at The Lea, Denham near Uxbridge, inside a 6-week programme — with a team of just 4 operatives, working entirely from scissor lifts at first-floor level. This is one of the few commercial schemes where the client appointed BAS Frames to deliver the full SFS […]
BAS Frames built 8 new flats on the roof of an occupied 6-storey block at Cross Keys, Edmonton N9, using a stick-build steel frame with joists lifted into place by hand — completed in 12 weeks.

BAS Frames designed, supplied and installed SFS infill achieving a 120-minute fire rating at the former Fulham Gas Depot on Imperial Road SW6 — double the industry standard, delivered for Erith in 6 weeks. A demolition contractor moving into building works St William acquired and managed the Imperial Road site. The gas depot building itself […]
BAS Frames added 4 storeys to an existing residential building at 56 Chatfield Road, Wandsworth SW11, on the bank of the River Thames — working from incomplete architect’s drawings and spotting a scaffold tie clash that would have cost the client significantly if it had been found later. Delivered in 10 weeks. The client was […]

BAS Frames delivered the SFS infill package to a 14-storey mixed-use tower and a 4-storey office building on Elmfield Way in west London, working with zero on-site storage and a just-in-time delivery regime, for HG Construction in 2018 over 12 weeks. The scheme combined residential and commercial space in a 14-storey tower alongside a separate […]
BAS Frames formed all external walls and window openings in SFS around a hot rolled steel frame at Morasha Jewish Primary School in Finchley N3, clad externally in CP board — the complete external envelope delivered in under 3 weeks in 2018. The main structure was built in hot rolled steel (HRS). Our scope was […]
Panellised construction delivers wall and floor panels built in a factory as flat, complete units, then assembled on site. It is not modular: modular means finished three-dimensional room units craned into place, which is a different product with different site requirements.
Perrymount Road in Haywards Heath is an 8-storey standalone building constructed entirely in light gauge steel, with no primary concrete or hot rolled frame — among the tallest of its kind in the UK. The design was signed off over 3 months before a single fabrication drawing was issued, because a panel made to a superseded drawing cannot be trimmed to fit.

BAS Frames installed a two-storey rooftop box in High Wycombe using a pre-panelised light gauge steel framing system, on a site directly alongside live railway infrastructure where crane restrictions meant the panels had to be delivered unboarded and manoeuvred into position by the installation team. The building is Castle House. The client was Crossville Developments […]
Perrymount Road in Haywards Heath is an 8-storey standalone building constructed entirely in light gauge steel — one of the tallest buildings in the UK delivered as a panellised SFS full build with no primary concrete or hot rolled steel frame. Most steel framing systems on a building this height sit as infill inside a […]
Stick-build means assembling the frame on site, component by component, rather than lifting in prefabricated panels. It is the method for sites panels cannot reach: occupied buildings, restricted craneage, complex geometry, or an existing structure where the as-built never quite matches the drawing.
That is why it dominates rooftop and airspace work. Below: 54 flats over 7 storeys for Croydon Council at Purley; 25 student blocks extended at 2 weeks each, using a single forklift with students in residence; and a 5-storey building in Slough topped with a stick-built steel pitched roof and individually formed dormer windows.
