About
Hi, I’m Jason Mirfin, an Architectural Designer who works closely with homeowners to turn their ideas into real, buildable plans. Whether you’re thinking about a home extension, loft conversion or something more unique, I’m here to make the planning process simple and stress-free.
I take the time to understand what you’re after, offer honest advice, and produce clear, detailed drawings that meet both your needs and local planning rules.
Feel free to get in touch - I’d love to hear what you’re planning.
