Cladding & Façade Design — London & the South East
The full façade design package — RIBA Stages 4–6, from approval drawings to production and as-builts. 100+ façades designed since 2015.
Design is the discipline Roytec was built on. Since 2015 we've delivered the full cladding design package on 100+ façades — taking the architect's intent to a fully coordinated, buildable, installation-ready set. We work across RIBA Stages 4–6: approval drawings, then production drawings, schedules, installation drawings and as-builts — every job overseen by a dedicated design coordinator. BIM-native and ISO 9001: visually true to the architecture, and resolved so it actually builds.
How we work
Approval design
We develop the architect's intent into elevations, sections and detail drawings for approval — defining the aesthetic and technical design of the cladding system (Stage 4 technical design).
Coordinate to Construction Issue
We revise against architect and consultant comments to 'Construction Issue', incorporating setting-out and structural calculations along the way. On fire and cavity barriers we go deep — every bespoke detail is worked through with the system manufacturer and the fire engineer, so the cavity-barrier strategy is manufacturer-verified and fire-engineer-approved, not assumed.
Production & schedules
Production drawings for manufacturing, plus full schedules — cladding panels, support structure (sub-grid) and ancillaries (insulation, top-hats, C-channels, fixings, membranes) — so procurement and fabrication run off one coordinated set.
Install & as-built
Clear installation and location drawings for the site team, on-site monitoring on request, and as-built drawings on completion (Stage 6).
What you receive
Frequently asked questions
What does a cladding design package include?
Everything your site team and the client's design team need to approve, build and sign off the façade: elevations, sections and detail drawings from approval through Construction Issue; setting-out, production and installation drawings; panel, support-structure and ancillary schedules; and U-value, wind-load, fixing and framing calculations, through to as-built drawings at handover. Fire-barrier, fire-stop, cavity-closer and cavity-compartmentation plans are part of the package — each bespoke detail worked through with the system manufacturer and approved by the project's fire engineer. Everything is issued through your CDE — Asite, Aconex or 4Projects — under our document control.
Which RIBA stages do you cover?
RIBA Stages 4 to 6. We take the architect's information through technical design and approval, into production drawings and schedules for manufacture and site, and out to as-builts at handover. If you want us in earlier, we work under a PCSA at Stages 3–4, ahead of Building Control and BSR Gateway approval.
Can you design to a system we've already chosen (Ash & Lacy, Sotech, Nvelope, Schüco…)?
Yes. We design within the manufacturer's system details for whichever rainscreen, curtain wall, render, metal or composite system has been specified — Ash & Lacy, Sotech, Nvelope, Schüco and the like. If the specified system won't resolve a particular detail, we tell you early and bring an alternative, rather than let it surface on site.

What it means for you
A dedicated design coordinator and a fully coordinated, buildable set — backed by £5M professional indemnity and £10M public liability cover — so panels are fabricated and installed from a resolved design, not a hopeful one.
