The result? A significant increase in headroom, floor space, and overall functionality. At Top Mark Conversions, we ensure your loft extension is completed with precision and care. From architectural plans and structural calculations to building control and final finishes, we manage the entire process for a seamless experience.

By altering the roof structure in this way, a Hip to Gable conversion unlocks the full potential of your loft, making it suitable for a spacious bedroom, office, or even an en-suite master suite. It also blends seamlessly with the existing architecture when done by professionals, maintaining your home’s overall look while increasing its functionality and value.

What is a Hip to Gable Conversions?

A Hip to Gable conversion is a type of loft extension designed to maximise space in homes with a sloped or "hipped" roof. These roofs typically have three or four sloping sides, which can restrict the amount of usable loft space. A Hip to Gable conversion addresses this by extending the sloping side of the roof (the hip) vertically, creating a straight gable end. This modification significantly increases the internal headroom and floor space of the loft, making it far more practical for everyday use.

At Top Mark Conversions, we handle every aspect of a Hip to Gable conversion—from structural design and planning through to construction and final inspection. It’s a smart way to unlock your home's potential without the cost and hassle of moving.
