The extension market just got disrupted. Forget the hassle, the months of traditional bricklaying, and the mountains of site waste. Warmer Room is the leading UK manufacturer of modular home extension kits, and we’ve packaged an entire extension into a simple, high-performance system designed for you.
We’ve taken our successful, innovative pod system and applied it to full extensions and conservatory replacements. This means you can offer your client a stunning, permanent extension faster and cheaper than traditional methods, guaranteeing you a competitive edge.
The Installer’s Dream: Modular Simplicity
We know complexity eats into your margin. Our system is engineered for rapid, stress-free installation:
- Pre-Assembled Modular Kit: The entire structure arrives in kit form, prefabricated in our facility. This unique pod system ensures installation is speedy, with an average build time of just 5 days for the core structure.
- No On-Site Disruption: Since the parts are pre-cut and pre-assembled, there’s drastically less cutting, less mess, and far less waste material to dispose of compared to conventional construction. This streamlines site management and saves you disposal costs.
- Suitable for Retro Fit: Our wall system is versatile enough to be retrofitted onto new or existing base foundations, expanding your pool of potential projects.
Built-in Performance You Can Guarantee
Every Warmer Room extension is engineered for maximum thermal efficiency, giving your clients a premium, year-round space while assuring you of quality materials.
Confidence and Compliance Wrapped Up
You can lead your sales pitch with absolute confidence:
- Pre-Approved System: Your Warmer Room Extension has been thoroughly tested and certified by an accredited national building control approvals agency. Use this certification to simplify your Building Regulations process and boost customer trust.
- 25-Year Guarantee: The entire system comes with a 25-year manufacturer’s guarantee, backing up your installation and providing long-term peace of mind for both you and your customer.
- One Supplier Solution: From the structural frame and premium insulation to the roofing (synthetic slate, shingle tiles, or EPDM for flat roofs) and rainwater goods, everything is supplied from one source, simplifying ordering and logistics.
