120 kWp Heritage-Sensitive Carport at 4-Star Bath Hotel

A 4-star boutique hotel group operating 8 sites across the South Coast and Cotswolds delivered a 120 kWp solar carport over the 95-bay guest car park at their Grade II-listed Bath property. The heritage-sensitive design uses Corten steel column finishes and slate-pattern PV glass to integrate with the surrounding Georgian conservation area.

Challenge

The hotel sits in a Bath Conservation Area, adjacent to Grade II-listed Georgian terraces. Conservation Officer consent was required in addition to standard planning. The car park is small (95 bays) and the structural envelope was further constrained by a 5m setback from the listed wall. Guest experience was critical — the carport had to be a feature, not an industrial intrusion.

Our Approach

  • Pre-application consultation with Conservation Officer — secured in-principle support before submitting full planning
  • Corten steel weathering finish (mellows to Bath-stone-toned patina over 18 months)
  • Slate-pattern bifacial glass-glass panels (rare specialist finish — sourced from Heckert Solar)
  • EV chargers in dedicated guest-priority zone, integrated with hotel PMS for room billing
  • Sponsorship plaque on carport detailing local heritage and project carbon savings
  • 12 × 7 kW chargers for overnight guests (full charge by morning) + 4 × 22 kW for short-dwell visitors

"The Conservation Officer was the deciding voice. Working with the design team early — before we'd even submitted planning — meant we got consent the first time. Guests genuinely love the carport. It's become part of the hotel."
