To add a rear extension to improve living space and gain a modern kitchen-diner

The semi detached house before extending

Simon Smith explains how the brief was achieved:

‘The house had full PD rights, so the extension could be built right up to the neighbouring boundaries. The side walls are three metres in height at the boundaries to conform with PD rights, but the feature rooflight rises to a height of four metres to maximise on natural daylight and create a sense of space at night when the glazing is uplit from inside.

‘Remodelling the entire downstairs floorplan has optimised space and flow, and allows for a good-sized utility area that was built close to the stairwell to free up the best views of the garden.

‘The homeowner wanted a modern kitchen but didn’t have a big budget, so we combined low-cost but good-quality kitchen units from Ikea with a high-end, bespoke concrete worktop, from Darksoi, to create a stunning kitchen-diner space that wouldn’t break the bank. The kitchen area cost £12,000, but looks as though it cost £25,000.

‘Overall, the design is smart, modern and, importantly, delivers on the owner’s design brief to create a unique home without spending a huge amount of money.’
