Use these shortcuts to explore your dream loft conversion:
Velux conversions are the simplest and most cost-effective type of loft conversion. They add Velux windows without changing the roof structure, making them perfect for bringing natural light into your loft.
Type: N/A – This conversion focuses on integrating roof light windows into the existing structure.
Best for: Properties with ample headroom where only minimal alterations are needed. Perfect for homeowners who want to enhance their space without extensive construction.
Dormer loft conversions extend the existing roof structure to protrude from the roof's slope, typically at the rear. This conversion type effectively adds both headroom and usable floor space.
Type:
Best for: Adding significant space; suitable for almost any house with a sloping roof. It's particularly effective in bungalows or houses where maximising vertical space is essential.

Mansard loft conversions involve altering one or both roof slopes to create an almost vertical 72-degree angle, significantly increasing the loft space.
Hip to gable loft conversions extend a roof's sloping ‘hip’ side into a gable end, increasing the usable loft space. Often, this is complemented by adding a rear dormer for even more space.
Modular loft conversions use prefabricated modules constructed off-site and installed into a prepared roof space, reducing on-site construction time and disruption.

In addition to the popular types of loft conversions like Velux, Dormer, Hip-to-Gable, Mansard, and Modular/Pre-Fab, there are other less common yet equally viable options to consider:
This variation of the dormer conversion is typically used on Victorian and Edwardian properties. It involves constructing two dormers – one on the main roof and another on the rear roof – which meet to form an 'L' shape. This type maximises available space and is particularly suited for terraced houses.
Similar to Velux conversions, skylight conversions involve adding skylight windows to the roof without altering its pitch or structure. This option is ideal for homeowners who want to add natural light without extensive structural changes. The main difference from a Velux conversion lies in the brand and style of windows used.
This type combines the mansard style with a rear dormer to maximise space. The steep sloping sides of a mansard roof are paired with a flat rear dormer, providing substantial headroom and usable space across the loft.
Side dormer conversions are useful for houses with hipped roofs where space on the sides can be utilised by adding a dormer.
This type is less common but ideal for creating additional space in more complex roof structures.
This conversion involves remodelling the roof to create a gambrel style, similar to a Mansard but with two different slopes on each side. This design allows for more space on the upper floor and is often found in rural or older homes.
A shell loft conversion completes the structural work necessary to make the loft a livable space, but leaves the finishing touches to the homeowner. This budget-friendly option allows for custom interior design.
A Piggyback conversion extends an existing loft conversion to maximise space or add features, like dormers or raised rooflines.
Ideal for homeowners needing more headroom or functional space, this type often requires planning permission and professional consultation to ensure feasibility and compliance with local building regulations.
