Loft Conversions Islington

Velux Loft Conversions (Rooflight Loft Conversions) – require minimal structural changes to the roof. Only roof windows, often Velux, get installed to harness natural light and ventilation. Additionally, flooring, plumbing, heating, insulation, and stairs make the room habitable. It is a cost-effective method when your loft already has adequate head height. 

Dormer Loft Conversions – built vertically from the existing roof plane to increase functionality, dormers afford more usable floor space. Usually added to the rear or side of the property, they feature dormer windows and skylights. They commonly have flat roofs and take a box shape, but pitched roofs also get incorporated.

L-shaped Loft Conversions – also known as dog leg dormers, Victorian terraced or semi-detached homes benefit from this design. They join two dormers right-angled, one on the main roof and the other on the rear outrigger. The shape creates two rooms, ideal for a master bedroom with an en suite. 

Mansard Loft Conversions – borrowing from the French Baroque style, they carry substantial alterations. An entire roof plane gets modified with a 72° wall and a steeper, flattish roof. The roof design maximises headroom, and dormer windows provide optimum functionality.

Hip-to-Gable Loft Conversions – the sloping side of a hipped roof gets replaced with a gable wall to give more head height and floor space. Semi-detached and end-of-terrace homes, built in the 1930s, commonly have hipped roofs that inhibit usable floor space. These properties can benefit from this loft conversion type. Some detached properties also have hipped roofs, suitable for a double hip to gable loft conversion.
