Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

About
Calum Duncan Architects was established in 2015 and has since grown with the completion of a number of imaginative and sensitive projects. We are based in Edinburgh and are working on projects throughout Scotland. We enjoy working collaboratively with our clients, consultants and contractors. As a practice we look to understand the most practical issues of a project while creating a unique and distinctive architectural character and atmosphere for each design proposal. We believe that good buildings are made by listening and understanding the users in an honest manner and leading the responses to these requirements practically, but with joy and imagination. We are interested in working across Scotland and comfortable with working for both private or public clients as well as cooperatives or community organisations. Our experience and expertise includes varied and often complex client organisations, but our ambition is to focus on any client’s ultimate aims and values. We value a close working relationship with the client and users. We especially enjoy working with clients who wish to live or work sociably with a proximity to nature and greenspace. This includes spaces and places for living, learning, working and relaxing, where our creativity and sensitive approach can improve enjoyment and wellbeing of our everyday lives in new or existing spaces.

"Architect" is a title protected by law - only people on the official Architects Register (held by ARB) may use it. Confirm they're on it before you commission a design.
Check the Architects RegisterOnly someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK. Ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts (a percentage of the build cost, a fixed fee, or an hourly rate) and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded (the planning application, the building-control drawings, and whether they will administer the builder's contract on site), and get it, and a portfolio of similar projects, in writing.
