You may have seen numerous loft conversions in London and wondered whether your new build, or period, property could accommodate a loft conversion. When you bought your home, it might have seemed like the perfect size, but life can quickly change with the addition of children, and you may find yourself wondering if adding a room at the top of the house could prevent you from outgrowing your home.

New Build Loft Conversion

Due to the construction methods used for new build homes compared to older properties, adding a loft conversion can be more challenging. This is why you will want to work with an architectural designer, such as GBS Architectural, to guide you through the process. It is likely that steels will be required to convert your loft to ensure the roof remains adequately supported.

Once you have decided to convert your loft, you want to make the most of the room you create. At GBS Architectural, we ensure that every design avenue is pursued in our role as loft conversion specialist. When you work with us, you can be assured that your design will be anything but dull. We take into consideration your space requirements, taste and the functionality you have been dreaming of.

Functional Design

Whilst many people think a loft conversion simply adds a bedroom, the space that you create can be used for whatever you desire. Living rooms, games rooms, libraries and galleries can all be created in your unused loft, adding another dimension to your home.

We work carefully on every design to ensure that a loft extension is both visually appealing and functional. Built in storage, space for an en suite, and the addition of dormers all ensure you can use the space within your loft to its full potential.


Although you may not be trying to add value to your home, adding an additional room is likely to have an effect on what your house is worth. Our architectural designers can offer advice on how your plans might be viewed by estate agents or prospective buyers.

Outgrowing your home and needing more space is incredibly easy, whether this is because your young family is growing (or growing up), elderly family members have moved in or because you will be spending more time working from home. The factors all point to one thing – more space.

Extending out may not be possible for you or it may not offer the solutions you need in terms of the space it will provide and this is where a loft conversion can come into its element. The are extremely flexible in what they can offer you now and into the future, the nature of a modern loft conversion means that the internal partitions are unlikely to be load-bearing and as such the space can be changed later if needed.

The best feature of a loft conversion is that it will usually take up dead space within your home, unlike an extension that will east into your garden space a loft conversion will take up the attic space above you which will maximise the potential of your home.
