A Full-Service Architecture Firm — Jersey Only
Planning Permission Jersey is a full-service architecture and planning firm operating exclusively in Jersey, Channel Islands. We handle every stage of the planning and building process in-house — architectural design, planning applications, structural engineering, energy assessments, flood risk reports, heritage statements, and builder-ready bye-law drawings.
Most planning agents stop at planning drawings. We don't. Our Bylaw Plus service produces drawings detailed enough for your builder to price and build from on the day approval lands — no second round of drawings, no delays, no interpretation required.
What We Do
Our bread and butter is house extensions and replacement windows — the planning applications that most Jersey homeowners need. But our in-house capabilities extend to new builds, loft conversions, garage conversions, listed building consent, change of use, planning appeals, fire safety surveys, structural engineering, and energy assessments.
Why Jersey Only?
Jersey has its own planning legislation, its own building bye-laws, and its own Island Plan. Understanding the Jersey-specific rules — the heritage designations, the flood risk zones, the permitted development thresholds, the bye-law requirements — takes years of working exclusively on the island. That is all we do.

A small, specialist team with deep knowledge of Jersey planning and building bye-laws.

Director & Associate Member RICS
Mike is the owner of J.Design and an Associate Member of the RICS. He first came to Jersey in 1984, working for the Planning Department as a Development Control Officer — processing Building Bye-Law applications, inspecting works on site, and helping write the Jersey Building Bye-Laws themselves. After a period with Allan Miller Architects he joined J.Design in 1993 and purchased the firm in 2004. Today J.Design submits around 100 planning and building bye-law applications a year, with an 85% planning success rate and a 100% bye-law success rate.
