Loft Conversions for New Build Homes

A loft conversion in a new build can be more complex than in older houses this is because many homes built after the 1960s were constructed using a W-shaped ‘fink’ trusses. W trusses tend to take up most of the room in the loft and without them, the roof would collapse. The way to remedy this is by installing steel beams and the good news is that most W shaped trusses will be of the required ceiling height for a loft conversion.

As a general rule, loft conversions tend to fall under permitted development. However, you may need to get planning permission or face restrictions from the developer of your new build. Some new builds can come with restrictive covenants and of course, leasehold new build homes are a separate issues, where you are likely to need the permission of the freeholder before any development can take place. If there are restrictive covenants surrounding your new build, you may need to seek the developer’s permission or try to have the restrictive covenant removed. Any restrictive covenants should have been made clear by your conveyancer, however, it is always worth checking your paperwork fully too.

New build loft conversion case study

Located in Thame, Oxfordshire this loft conversion took eight weeks to complete, including all electrics and plumbing. The project consisted of a large rear dormer which comprised of a master bedroom, dressing area and en-suite bathroom. To ensure that plenty of natural light came into the room, large double doors and windows were installed, along with a Juliet balcony.

The bathroom featured a large walk-in shower and freestanding bath under a large skylight. The owners of this home have used a natural palette of clean whites and muted brown mosaic tiles. In the eaves, a bespoke storage and shelving unit was built.

To ensure ease of access, a new stairwell was built, and the existing staircase was refurbished. The décor was designed to ensure the space looked as large as possible with the use of fresh and muted colours. A large window was also installed into the dormer to allow as much natural light in as possible.
