We recently obtained planning consent for an exciting scheme to extend this family home in North Oxford and we’re hoping to commence the build soon. We’ve been able to create a second floor to this dwelling by extending the existing loft in two directions – a hip-to-gable and a rear dormer roof extension. Then, over the ground floor, we’ve extended to the side, wrapping round to the rear with a single storey extension, which dramatically increases the ground floor footprint and offers a fantastic kitchen/dining/living space connected to a south-facing garden offering plenty of natural light and a vast sense of space.

Proposed plans and elevations for a house extension and transformation to a 1930s semi-detached house in Oxford.


Our in-house team of architects and designers have been busy working on this exciting new house extension and transformation in central Oxford. The existing site is a classic 1930s semi-detached house located in a well-known residential area east of the centre. Our client, in this case, is in the building trade so knows exactly what he wants from the project and the type of house extension he wants us to design and build.

His brief is to maintain the period appearance of the original front elevation of the house but add a contemporary double storey side extension and a rear kitchen extension.  We are proposing clean timber cladding and a smooth render to the external walls with grey slimline windows and doors along with matching grey aluminium capping around the parapet roofs. This should provide the sleek-looking house extension he is after.

Overall, the house extension will significantly increase the internal floor area of the dwelling. A sense of light and space is required for the large, open-plan kitchen, dining, living space and so we have included large, flat roof lights and bifolding doors to connect with the garden with a glazed return detail.

As well as some extensive internal remodelling and the external transformation, we have also designed a garden studio, which will be situated at the bottom of the garden. This, along with the house extension will result in a fully-featured family home, designed for modern living and that will become a vastly improved building in terms of thermal efficiency with the loft having already been converted.

Once planning approval has been obtained for this house extension project, Cherwell Design & Build will look forward to starting the build phase in order to complete the entire design and build process.


In progress…this is set to be a stunning kitchen extension and renovation to a Victorian town house in South Oxon. On track for completion later this year.
