The Brief

Our clients approached us with the dream to transform their existing loft extension, and create a complementary addition of a mansard dormer extension above the existing outrigger. The existing space facilitated a small bedroom and en-suite, but the desire to create a fully functioning master suite and additional bedroom with a large shared bathroom and plenty of storage space, was a key element of the initial brief.

Whilst working with us, our client also looked to renovate other areas of the family home, including the ground floor open-plan living area, providing a new, bespoke kitchen and new flooring. We recommended this be done at the same time to save both time and money, and so we set to work designing their dream space.

Our Solution

As the property had already been extended and exceeded their permitted development rights, we had to go through a householder application to obtain that much needed extra space. This led to us having to make a slight compromise, as the council would only accept the extension if a mansard style roof was incorporated to reduce the impact on the adjoining neighbours. This gave all the more reasons to be especially innovative, such as creating concealed storage pockets in the eaves, to make the most out of the available space. By using similar roof tiles to clad the proposed extension, the council were happy that we remained subordinate to the original dwelling.

After moving swiftly throughout the planning stage, our interior designers began preparing the necessary documents and designs for tender, not missing any tiny detail, from door handles to paint colours. Two large roof lights were proposed on the front roof slope which was South facing and would flood the master bedroom with natural light. The newly extended loft space was to become the additional bedroom, with the new bathroom sandwiched in-between.

Summary of Works

The final outcome was a subordinate addition on the outside, with bright, well-considered interior spaces – perfect for our client’s growing family’s needs. A miniature dormer window to the rear c0ompletes the elevation, creating a subtle but sweet form of direct outlook to the rear garden.
