# Elongated London Courtyard Houses Whittaker Parsons Adds a New Extension to the Blythe Hill House By Amy Duong | Published 2025-06-16 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/blythe-hill-house References: [whittakerparsons](http://whittakerparsons.com/)  Architecture firm Whittaker Parsons has just added a long extension to a [terrace home](https://www.trendhunter.com/trends/abbie-abbotsford-terrace) first built in the 70s dubbed the Blythe Hill House in Southeast London. The goal was to create a courtyard home filled with natural lighting. The existing home has undergone renovations, and the extension adds a 14-meter-long structure using [hempcrete blockwork](https://www.trendhunter.com/trends/hemp-house) and stretches through the garden's length. Camille Parsons explained more about the design concept, noting "Breaking from the usual infill or extruded approach, this extension to a 1970s terrace utilises the plot's extra width to form an [elongated extension](https://www.trendhunter.com/trends/reciprocal-house), running perpendicular to the rear elevation. This created a private shaded courtyard garden and provided unexpected spatial variety and flexibility within the home."
