# Lightweight Timber Extensions Easi House by Nimtim Architects Reworked Using Exposed Easi-Joists By Amy Duong | Published 2026-02-10 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/easi-house References: [dezeen](https://www.dezeen.com/2026/02/09/easi-house-nimtim-architects/) & [nimtim](https://www.nimtim.co.uk/)  The Easi House by [Nimtim Architects](https://www.trendhunter.com/trends/hemp-house) is a residential extension project in London that uses exposed engineered timber to shape light-filled domestic spaces. The project extends a [Victorian terrace](https://www.trendhunter.com/trends/meadow-road) with a rear and side addition designed around easi-joists, which are typically concealed in construction but are left visible here as both structure and finish. The intervention reorganises the ground floor to create an open-plan living, dining, and kitchen area connected to the garden. Easi-joists are used across the ceiling and walls, casting shadows as daylight enters the space and giving the extension a distinctive visual rhythm. Bricks reclaimed from the original building are reused as flooring, reducing material waste while maintaining continuity with the existing structure. The extension relies primarily on [timber construction](https://www.trendhunter.com/trends/common-woods), limiting steel use to a single column.
