FEATURED PROJECT · BATTERSEA, LONDON · 2017
TRJ developed an annexe for the Royal College of Art in Battersea in 2017. The project was built with Dr William Hogan-O’Neill. Supersips UK supplied the SIP panels.
The photos show steelwork, the floor frame, panel fitting and work inside the building. They also show the finished exterior.
This project remains part of TRJ’s commercial construction portfolio. The gallery retains every photograph from the original page.

STRUCTURAL INSULATED PANELS
SIP construction needs coordinated detailing.
SIPs have structural faces bonded to an insulated core. Their role in the building is set by the overall design.
Panels can help organise the build. The base, joints, supports, windows and services still need careful design. Each part affects how the finished building performs.
Start with how the building will be used. Offices, shops, healthcare spaces and warehouses need different layouts and services. The design must suit the proposed use.
COMMERCIAL BUILDING DESIGN & CONSTRUCTION
The original page highlights insulation, structural support and practical installation. Those aims need a project-specific specification rather than assumptions about cost or performance.
Coordinate the panels with the structural design, foundations, openings and any supporting frame. The gallery illustrates steelwork and panel construction within one commercial project.
Design the walls, roof, floor, windows and joints together. Heating, ventilation and how the building is used also affect comfort and energy use.
Plan site access, lifting, structural work and services before fitting the panels. The build sequence needs to suit the site.
Develop the room arrangement around the business or institution. Establish occupancy, equipment, circulation, power, lighting, ventilation and any specialist facilities before the specification is agreed.
Choose cladding, glazing and finishes in relation to the design and setting. Weather protection, moisture management and maintenance requirements depend on appropriate materials and detailing.
Compare quotes against the agreed structure, finishes and services. Costs vary with the design, access, ground and fit-out. Panel choice alone does not guarantee savings.

FROM THE SITE TO THE FINISHED BUILDING
The gallery shows more than the finished exterior. You can see the frame, floor, stairs, panel fitting and work inside the annexe.
The photos show how the building came together. For your project, share the drawings, site limits and intended use. TRJ can then discuss the build with you.

YOUR QUESTIONS ANSWERED
Answers based on the original commercial-building description and the information needed for a new brief.
The portfolio records a 2017 annexe for the Royal College of Art in Battersea, London. Its 15 photos show the build and the finished space.
TRJ developed the annexe together with Dr William Hogan-O’Neill. The original project credit identifies his architectural qualifications and professional credentials, including RIBA and ARB.
The SIP panels for the Royal College of Art annexe were supplied by Supersips UK, as recorded in the original TRJ project description.
SIPs have strong outer faces and an insulated core. They can form part of the structure and insulated shell. Joints, openings, extra supports and service routes must suit the design.
SIPs can be considered for offices, shops, healthcare spaces and other commercial uses. The design must suit the layout, people, equipment and services. A classroom and a specialist workspace may need different solutions.
