The brief: a South West London loft conversion

This South West London project combined a loft conversion with refurbishment of the kitchen on the floor below. The main brief was to create a new bedroom and en-suite bathroom within the existing roofline. The available space was limited, so the new rooms and their connection to the rest of the house needed careful planning.

Space and planning constraints

The loft design had to work within height limitations set by an approved planning application. The challenge was to fit the bedroom and bathroom into the small available space while connecting the new accommodation to the existing house by stairs. The roofline and approved height limits shaped the design response.

Technical drawings and construction support

Horizon Architecture produced detailed construction drawings and considered the plumbing and electrical requirements of the new accommodation. We worked closely with builders during construction and coordinated with building control authorities. Our scope extended from design through to implementation, with support for the builders as the loft took shape. The drawings and coordination were particularly important where the new bathroom, stairs and existing structure came together.

Solution and completed scope

The completed conversion provided a bedroom and en-suite bathroom connected to the existing house. The client also used the project to update the kitchen on the floor below. That work included removing a wall to create an open-plan living area, bringing a second part of the home into the refurbishment scope.
