Koru Architects is an award-winning design-led practice specialising in eco-design. Our mission is to create spaces that are delightful, comfortable and sustainable. We work throughout Sussex and the South-East on residential and commercial projects, both new-build and extensions/alterations. We now aspire to diversify into the education, leisure and healthcare sectors.With our passion and 30 years of professional experience, we put your needs and dreams at the centre of our design process. Our designs are characterised by creative use of light and space, lateral thinking, attention to detail and the careful selection of natural materials. One of our key specialities is using sensitive design to win planning approval in restricted places such as conservation areas and the South Downs national park.As a small and growing business, our staff enjoy an informal working environment where self-motivation, autonomy and responsible self-allocation of tasks are valued. Working within a contemporary zero-carbon office provides a constant inspirational reminder of our ethos. Our director Mark Pellant loves architecture, design and creating a better built environment. He set up Koru Architects in 2000 to put his environmental principles into action.Beyond our primary goal of designing beautiful, high-performance, low-energy spaces for our clients, our work also feeds into our broader vision of a more sustainable society. With every design, we aim to enhance the built environment and the experience of its users, advance the green building movement and promote harmony with nature.
scope: Koru Architects undertook the whole project from design to completion. Koru were also the clients. The house won the RIBA Downland Prize for sustainability 2011.
aims: The brief was to create a sustainable, light-filled home and studio for Mark and Abi, the directors of Koru Architects.
measures: Roof integrated 4kwp solar PV panels provide the electricity demand and solar thermal panels supplement a wood pellet biomass boiler to provide energy for space heating and domestic hot water. Rainwater is harvested for WC flushing and garden use.
monitoring: Air tightness test result on completion was 1.5m3/hr/m2 @ 50Pa. For electricity production/consumption, after the 1st year in use the building consumed 3900kwh and produced 3832kwh.
scope: Koru Architects undertook the whole project from design to completion.
aims: A large extension to a period cottage within the conservation area of Clayton at the foot of the South Downs. This two-storey rear extension almost doubles the floor area of the existing cottage, and has created a new south facing facade to both enjoy the views of the South Downs and to maximise passive solar gain.
measures: The new wing of the house has made extensive use of locally-sourced sweet chestnut for cladding and high-performance doors and windows. The existing oil heating system was replaced by an efficient wood-pellet boiler and solar thermal panels.
monitoring: The thermal performance of the existing cottage was upgraded, but since the cottage was doubled in size, it is difficult to give any meaningful performance data.
scope: Koru Architects undertook the design, planning, building control and onsite queries.
aims: New contemporary 4/5 bedroom house within the conservation area of Lewes. This sensitive addition to the street scene respects the scale, rhythm and materials of its neighbours, making references to surrounding architectural features in modern way.
measures: The rear south-facing elevation has been more highly glazed to exploit winter solar gain and sun louvres help to exclude unwanted sun in the summer. The majority of the materials used in construction are natural materials, low in embodied energy, non-toxic and recyclable or biodegradable.
