Business Description

We are a friendly, contemporary architecture practice where sustainability is central to our design process. We love helping clients on the way to having a beautiful, practical, sustainable home, or fruitful development, which brings joy to everyday life.

Our approach reflects director George Morgan’s 15 years experience at leading design-led architectural practices, and our central ethos of sustainability. George is a Certified Passivhaus Designer, and our work also considers the embodied impacts of construction, transport and the social impact of design.

Suburban Infill Passivhauses

One Point Five Architecture has submitted a planning application to build a terrace of three new houses in a suburban infill site in Dartford, Kent. An easy walk to the town centre and train station, densifying suburban areas like these can help reduce car use and emissions associated with transport.

The houses are staggered to accommodate site geometry and create a threshold space at the front. This planted threshold space balances views out over the communal entrance area with privacy to the dining space and kitchen inside. Solar shading to this south elevation mediates preventing summer overheating with letting in the low winter sun deep into the plan.

The houses are to be built to the ultra-low energy Passivhaus methodology, using mostly bio-based materials in the construction.

Suffolk Passivhauses

One Point Five Architecture is proposing a development of three new homes in the back garden of a house on the edge of a village in Suffolk.

The proposals reinterpret the traditional local vernacular as a way to achieve high-quality, low-impact new homes in an area of relatively low land values.

The steeply pitched gables of the half timbered houses in the area are expressed as a triangular form with a timber A-frame structure. The simplicity and economy of this system more than offsets the cost of achieving the Passivhaus standard. The A-frame structure facilitates screw pile cantilever foundations, removing the need for concrete, which reduces construction impacts.

The houses are arranged in a friendly layout, with the homes fanning out to optimise sunlight and privacy to the large living room windows and raised deck patios.

Wild City

Our competition entry for an urban extension of Letchworth Garden City seeks to address climate and biodiversity breakdown, the housing crisis, social atomisation around two themes: Wild and City.

Half the site area is rewilded to reconnect residents to ecological processes and give children have exciting places to play.

The developed site area is densely built, like a mediaeval town. Cosy, neighbourly streets, and more open, civic squares are linked by a lively main street. This approach achieves three times more homes than the competition brief suggests.

Wild City prioritises walking, cycling and a new free bus route, with car use limited. This creates a safe, bustling, sociable urban environment, prioritising walking and socialising, with places to stop and chat.

Rather than the car-based suburbanism of so many contemporary new places, Wild City combines genuine nature with a real sense of urbanity, showing that more sustainable settlements can enrich our lives.
