Belfast architect for one-off homes, extensions and remodelling
I’m Marcin Piotrowicz — a Belfast-based RIBA Chartered and ARB registered architect. I work with homeowners on one-off houses, extensions, remodelling and careful upgrades to existing homes.
My full name is Marcin Witold Piotrowicz. You’re welcome to call me Vito — a shorter name taken from my middle name, Witold.
Over more than 20 years in architecture, I’ve worked across design, planning, technical detailing, approvals and construction-stage problem solving. My work combines spatial design with practical building knowledge, so projects are not just visually strong, but buildable, comfortable and well thought through.
Recent work includes Long House / The Gallery, winner of BBC Northern Ireland’s House of the Year.
