Margin is a Belfast-based architecture and planning consultancy helping you understand what your space could become.

Clear thinking comes first.

Before a line is drawn or an application submitted, the right questions come first. What will genuinely improve your home? What will stand the test of time? What will add real value, not just now, but when it matters most?

From planning feasibility and permitted development advice, through to detailed design and interiors consultancy, every stage is guided carefully. Considered. Explained in plain language. Designed around the way you actually live.

Listen

Begin with clarity.

Before drawings, applications, or decisions, the focus is on understanding the space and the people who use it. Whether it's a home that needs to adapt, a site with untapped potential, or a space that no longer works the way it should, clarity comes first. What's possible, what makes sense, and what feels right for the future of the space.

Plan

Plan with confidence.

Policies, constraints, local guidance, and neighbour considerations all shape what's achievable. The process is managed from early feasibility through to submission, carefully considered, clearly presented, and aligned with planning policy. Strategic thinking at this stage can make a real difference. Each step is explained along the way, so you stay informed and confident as the application progresses.

Shape

Design with purpose.

Space is refined by considering how light moves through it, how rooms connect, and how everyday life flows. Residential or commercial, large or small, the aim is the same: calm, functional spaces that feel effortless to use and support how you live, work, and grow.
