Internal alterations bye-law approval in Jersey.

Frequently Asked Questions

Alterations & Windows we have taken through planning

Listed Window Replacement

“Replacing the old windows on our cottage in St Ouen felt like a legal minefield. The team sorted out the historic environment details and drawings without any fuss, and the planning department approved the slimline double glazing on our first attempt.”
Jean Le Brun, St Ouen

Solar Panel Array

“We wanted in-roof solar panels on a roof facing the street in St Helier. Planning initially pushed back, but the team handled the submission brilliant and won the approval for us.”
Sophie Marett, St Helier

First Floor Glass Balcony

“We were worried a glass balcony on our first floor would trigger privacy complaints from next door. The architectural team designed frosted side panels into the drawings, which satisfied the planning officer straight away.”
Emma Le Quesne
