This mid-terrace period home in London was full of old-school charm but felt small and outdated. The owners wanted a bigger, modern space that kept its historic feel while being easier on the planet and their wallet. Our team at ERG, a group of technical pros who focus on smart design, cost balance, and top-notch quality, took on the project. We delivered a full renovation that transformed the property into a spacious, eco-friendly home without breaking the bank.

The Problem
Built in the early 1900s, this house was short on space and tough on energy bills. Leaky windows and an old heating system were costing the owners too much. They wanted more room, a comfier home, and a jump in property value—all while keeping the original character. This was a tricky balance, but ERG’s technical expertise and focus on value made it possible.

What We Did
At ERG, we’re all about efficient design and cost balance, so we planned every step to maximize impact while keeping costs in check. Using our high-quality delivery and strict quality management, we rethought the house from the ground up, adding space and eco-friendly features.

Side and Rear Extension: We added a rear extension and filled in the side, boosting living space by 50%. The open-plan kitchen and living area now gets plenty of light, making it perfect for family hangouts or hosting.
Loft Conversion: We turned the roof into two big bedrooms and a home office, adding 80 square meters of practical space. Skylights and custom storage make the loft both useful and comfortable.
Smarter Layout: We redesigned the interior to use every inch wisely. The new layout feels open and flows well, with better insulation to keep heat where it belongs, cutting energy waste.
Eco-Friendly Upgrades: We installed high-performance insulation, triple-glazed windows, and a smart heating system, slashing energy use by 40%. Using wood from responsible sources, recycled materials, and low-chemical paints, we made the home healthier and greener.

The Results
The house is now a completely different place, and the owners couldn’t be happier:
Higher Property Value: Our smart renovations bumped the home’s market value by 25%, making it a standout in London’s tough market.

Better Living Space: The bigger, brighter interior feels high-end yet practical. From the open living area to the cozy loft bedrooms, the home is perfect for everyday life.

Great Return on Investment: By balancing cost and quality, we delivered a strong payoff, proving that sustainable design can be a win for both the planet and the pocketbook.

Lower Bills: The owners now save 40% on energy bills, and the eco-friendly materials make the home a healthier place to live.

Why This Matters
This project shows what ERG’s technical and value-focused approach can do. We took an old home and made it modern, green, and valuable while keeping its heart intact. Our efficient design and cost-conscious mindset, paired with high-quality delivery, created a space that’s great to live in and smart for the long haul.
