Alterations & Windows we have taken through planning
Jersey projects we have prepared, submitted and seen through to decision, in our clients' own words.
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.”
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.”
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.”
Internal Structural Wall Opening
“Even though internal changes do not always need full planning, being in a protected building meant we needed formal consent for opening up the back wall for bifolds. They managed the paperwork efficiently.”
External Wall Insulation
“Adding external wall insulation to a 1970s house changed the outer appearance drastically. The team helped us pick an approved finish and submitted the planning notice without fuss.”
Roof Terrace with Glass Balustrade
“Turned our flat roof into a sun terrace. The site plans clearly proved we would not overlook the neighbouring gardens, so the planning officer gave it the thumbs up.”
Timber Sash Replacements
“Upgraded single glazed sash windows in a protected area to double glazed timber replicas. The drawings and wood profile specs satisfied the planning department completely.”
Slate Roof Replacement
“Changing the roofing material on an older traditional home needed explicit permission. The team provided material samples and drawings that made approval straightforward.”
