We Understand Buildings, Not Just Software
CasStudio is an architectural modelling and visualisation studio founded in 2008, with a growing specialist focus on shadow diagrams, shadow analysis and planning-focused visual documentation for international project teams. We specialise in shadow diagrams, BRE 209 daylight/sunlight assessments, 3D visualisation and point cloud to BIM for architects and developers across Australia, the United Kingdom and Europe.
Architectural Foundation
CasStudio was founded in 2008 by Gligor Nedelkoski, who brings a strong architectural background and a deep understanding of how buildings work — from planning regulations and building codes to construction detailing and material specification. This architectural foundation is what separates our work from software operators who produce technically correct but contextually naive deliverables.
When we prepare a shadow diagram, we understand why the council or planning authority is asking for it. When we run a BRE 209 daylight assessment, we understand what a planning officer needs to see to approve it. When we produce a 3D visualisation or draw as-built plans from point cloud data, we understand the logic of the building's construction. This understanding is reflected in every deliverable we produce.
From Europe to Australia & the UK
We started with 3D visualisation and point cloud to BIM documentation for European clients — residential and commercial projects across Switzerland, Germany and Austria. From 2013, we began working with UK architects and project teams, and from 2018, expanded into shadow diagrams and solar access work for Australian architects.
Today, our two largest markets are Australia — where we prepare shadow diagrams and solar access assessments for Sydney, Melbourne, Brisbane and Perth — and the United Kingdom, where we serve architects and planning consultants across London, Manchester, Birmingham, Leeds and beyond with shadow diagrams and daylight/sunlight assessments. In Switzerland and Central Europe, we remain a trusted white-label partner for scan-to-BIM documentation.
One Studio. One Point of Contact.
CasStudio is a small specialist practice, led by its founder since 2008. When you work with us, you deal directly with the person who models your scheme and writes the report — no account managers, no handoffs between departments. Your brief goes straight to the person doing the work.
This means faster communication, fewer misunderstandings, and consistent quality across every project. It also means we are selective about the work we take on — we focus on what we do best and deliver it on time, every time.
