About Apex Lofts

Over 30 Years of Transforming Lofts Across Hertfordshire & North London

Since completing our first loft conversion in 1992, Apex Loft Conversions has successfully converted hundreds of underused attic spaces into fully functional bathrooms, bedrooms, and multi-functional rooms.

We are a proud member of The Guild of Master Craftsmen and carry full public and employer's liability insurance for complete peace of mind. We use only the highest quality materials, including premium Velux roof windows and German-engineered window systems.

Three generations of family experience go into every project we complete. We focus on craftsmanship of the highest standard, realistic pricing, and fixed-price quotations so you're never hit with surprises.
