Welcome

At PlanB, we bring buildings to life—from concept to completion. Based in Guernsey, we offer expert architectural and structural engineering services that combine creativity, precision, and practicality.
Whether you’re planning a new build, renovation, or extension, we design spaces that are not only beautiful but buildable, safe, and sustainable.
We go beyond design. Our upcoming Contract Administration and Project Management services ensure your project runs smoothly, stays on budget, and meets every expectation. From managing contractors to overseeing construction quality and timelines, we act as your trusted partner throughout the journey.
With PlanB, you get more than drawings—you get a team that understands the full lifecycle of a building and delivers solutions tailored to your needs.
