Introduction
Thank you for taking the time to talk with me about your project. Based on our conversation, I’ve put together this report to reflect what matters most to you. Inside, you’ll find examples of the systems we discussed, how they would work in your space, and what you can realistically expect in terms of performance and cost.
When you’re ready, you can book a TEAMS call with me and I’ll walk you through everything step by step.
Your Key Area
- Roof Lantern 2420mm x 5270mm (12.75m²) in open plan living space rear of home extension.
Your Priorities
- Priority 1: Reduce heat gain via the roof lantern to help support the air-conditioning loads.
- Priority 2: Manage excessive brightness to maintain a usable living space on sunny days
- Priority 3: Keep the flies out of the roof lantern. This will support your summer indoor outdoor living.
- Priority 4: Improve heat loss to maximise the benefit of underfloor heating.
