Sustainable Building Questions Answered

Common questions about eco-friendly construction.

What is sustainable building?
Sustainable building uses eco-friendly materials, energy-efficient designs and construction methods that minimise environmental impact. This includes better insulation, renewable energy systems, natural materials and designs that reduce energy consumption and carbon footprint.
How much does sustainable building cost?
Sustainable construction typically costs 5-15% more upfront than conventional building, but delivers significant long-term savings through reduced energy bills. Many eco features pay for themselves within 5-10 years. We provide detailed cost-benefit analyses with every quote.
What sustainable materials do you use?
We use FSC-certified timber, recycled materials, natural insulation like sheep's wool and wood fibre, lime-based renders, low-VOC paints and finishes, and locally sourced materials where possible to reduce transport emissions.
Can you retrofit existing homes?
Absolutely. We specialise in eco-retrofitting existing properties with improved insulation, triple glazing, heat pumps, solar panels and airtightness improvements. This can dramatically improve energy efficiency and comfort.
Do you install renewable energy systems?
Yes, we install solar PV panels, air source heat pumps, ground source heat pumps, battery storage systems and mechanical ventilation with heat recovery (MVHR). We handle all design, installation and certification.
What certifications do you work to?
We work to Passivhaus principles, EnerPHit for retrofits, BREEAM standards and Building Regulations Part L. Our team includes certified assessors who can guide you through achieving formal certification if required.
