5 Steps to a greener house extension or renovation

Build a sustainable, energy-efficient home extension with expert architectural guidance from Acre Design, trusted by homeowners across North Tyneside, Newcastle, and Northumberland
If you’re planning to extend or renovate your home in Newcastle, Northumberland or North Tyneside, this is the perfect time to embed sustainability at the heart of your design. A well-planned, eco-friendly extension not only lowers running costs but also future-proofs your property and enhances long-term value.
Here are five practical ways to make your home extension greener, healthier and more efficient.
1. Upgrade insulation and glazing
Up to 40% of a home’s heat can be lost through walls, roofs, and poorly insulated windows. Investing in high-performance insulation and energy-efficient glazing will make an immediate difference. Consider triple glazing, airtight detailing, and natural insulation materials such as recycled denim, wood fibre or sheep’s wool. The result: lower bills, improved comfort, and a home that performs beautifully all year round.
2. Reuse and reduce water
A rainwater harvesting system can collect thousands of litres annually, perfect for flushing toilets, watering gardens or even running washing machines. Combine this with low-flow fittings, dual-flush toilets and aerated taps to make water efficiency part of everyday living — simple upgrades with lasting impact.
3. Smarter heating and control systems
Smart thermostats and zoning controls help you heat only where and when needed. Even reducing temperatures by one degree can make a noticeable difference to your energy use. Integrating smart controls into your renovation gives you greater comfort, insight, and savings — all while reducing waste.
4. Choose eco-friendly finishes
Sustainable design extends to the finishes you choose. Opt for VOC-free paints, lime or clay plasters, and FSC-certified timber flooring. Natural materials support healthy indoor air quality and create spaces that feel calm, tactile, and timeless — an aesthetic that complements Acre Design’s architectural approach.
5. Explore renewable energy options
If your project involves substantial upgrades, it’s an excellent opportunity to introduce renewable systems. Air-source and ground-source heat pumps, solar panels, or efficient biomass stoves can all reduce reliance on fossil fuels and lower emissions. Our team can help you assess what’s feasible for your site, budget and long-term sustainability goals.
