Bright ideas in your roof space.
We are passionate about bringing light into your life and your home. A loft conversion is the obvious way to experience the changing light of each season and to bring natural colour into your home.
Is your dream room waiting under your roof?
A master suite, a guest bedroom, a home cinema, or a play space for the children? A loft conversion is one of the easiest ways to extend and add value to your home.
Frame a view
One of the best things about being up in the rafters is the panoramic views you will have from your new vantage point. Make the most of them with strategically positioned windows.
Make the most of original features
If you live in a character property, take advantage of bare brickwork and timber beams to offset modern interiors.
Use every inch of space
Make slanting ceilings work for you by positioning baths in areas with low head heights or using tight spaces for storage.
Think outside of the box
Loft conversions are most commonly used as extra bedrooms, but they don't have to be - attic spaces can be transformed into stunning offices, dining areas or family rooms.
Design available for all properties
Common Types of Loft Conversion
There are 4 common types of loft conversion popularly constructed in the UK. A simple flat roof Dormer conversion is the most popular. A Mansard loft conversion is constructed by raising the party wall. A Hip to Gable conversion straightens an inwardly slanted end roof to create a vertical wall. A Roof Light conversion is where you do not alter or expand the existing space at all, but simply add in windows and reinforce the floor to transform an attic into a comfortable living space.
// Roof Lights
Roof light conversions are by far the cheapest and least disruptive option, as you won't have to make any changes to the shape or pitch of the roof. Instead, it is simply a case of adding in skylight windows, laying down a proper floor, and adding a staircase to make the room habitable. However, you will need to have enough roof space already without having an extension for this type of conversion.
A dormer loft conversion is an extension that protrudes from the slope of the roof. Dormers, in particular flat-roof dormers, are the most popular type of conversion. They are suitable for pretty much any house with a sloping roof. Dormer conversions are less expensive than mansard or hip-to-gable conversions, but will still add a good deal of extra headroom and floor space.
Hip-to-gable conversions work by extending the sloping 'hip' roof at the side of your property outwards to create a vertical 'gable' wall, creating more internal loft space. This type of conversion will only work on detached or semi-detached houses, as it requires a free sloping side roof.
If you have a detached house with sloping roofs on either side, you can build on both of these to create an even more spacious double hip-to-gable extension.
Mansard extensions run along the whole length of your house's roof and will alter the angle of the roof slope, making it almost vertical. These tend to be the most expensive type of conversion, but will result in a significant amount of extra space. Mansard conversions are suitable for most property types, including terraced, semi-detached and detached houses.
Maximise space and value
Loft conversions are one of the most cost effective methods of gaining extra space in your home, they are typically cheaper than other home extensions in relation to the additional floorspace. They can also quickly add space to your property without being too disruptive – you should not need to move out while the work is going on.
A cost effective method of rejuvenating your living environment
The beauty of a loft conversion is that they can even be self-contained with their own front door, meaning families can live together, but maintain their independence.
Create a cozy new hangout, or an inspiring kitchen dinner to entertain guests
Lofts are not just handy for storing Christmas lights and dusty heirlooms – a well-designed conversion is one of the most cost-effective ways to gain more living space and can add value to your home.
