Cannock Mill Cohousing nears completion

Nearly a decade since its first conception, a cohousing project of 23 homes at Cannock Mill in Colchester is nearing completion. Members of the group are now planning planting for their gardens, and looking forward to moving in to their new homes.

Designed by PHT member Anne Thorne Architects, the scheme sits naturally within its wooded valley setting. The three contemporary terraces of new houses make a visually comfortable and interesting transition, via two progressively lower timber-clad, metal-roofed blocks of flats, to the original mill building.

The Grade II listed Cannock Mill is the heart of the scheme. A mill has stood on the site since 1611, and the current building dates from 1845. Appropriately, this will be the ‘common house’ for the group – a core concept in cohousing, such spaces allow for the community to come together and truly share facilities. The ground floor will contain two guest rooms to allow members who live in one of the smaller units the ability to host visitors, as well as a much-in-demand workshop type space in the old lean-to. The middle floor houses the common dining area and semi-commercial kitchen. The top floor, open to the rafters, is a gathering space in the best sense.

It’s visually separated from the new flats next door by a fully glazed connection to a lift shaft – the whole development is designed to Lifetime Homes standard, anticipating any current or future access requirements.

Close collaboration between architect and client led to the decision to build to Passivhaus standard, and Anne Thorne will be talking about the project as an exemplary community scheme that approaches zero carbon at this year's UK Passivhaus Conference, Passivhaus and the road to zero carbon. Join us on 13 November in Leeds to learn more.

We adopted the Passivhaus standard to meet CMCC's core aim to keep our carbon footprint as light as possible. There are two fundamental reasons for this: firstly, we care about the environment and wish to leave planet Earth intact for our children and grandchildren; secondly, we don’t want to be paying high energy bills.

What is cohousing?

  • Cohousing is co-designed with intentional communities

  • Cohousing includes the provision of both private and common facilities, providing a balance between privacy and community

  • Cohousing is of a size and scale to support community dynamics for easy informal communal contact
  • Cohousing embeds collective resident control and stewardship into its legal form and decision making
  • Cohousing communities are inclusive and part of the wider community

- UK Cohousing network

Landscaping includes restoration of the Mill Pond to serve the dual purpose of water management, on a site with difficult ground water conditions - the north facing slope,composed of clay and water-bearing gravel strata, drops 11 metres across the site - as well as providing an attractive central feature.  There may well be wild swimming.

PHT member White Haus have supplied the timber cassette structure, filled with cellulose insulation, and PHT member Alan Clarke is in charge of the MVHR and other services.

One home is still available – a three-bedroom terraced house with integral garage. The open plan kitchen / dining / living room is on the top floor, offering egress on to a balcony with views to the south over the communal garden and kitchen garden plots.

And the group has just received planning permission to convert Cannock Mill House, a large Victorian house that sits in a corner of the Cannock Mill plot, into flats, creating three more homes, to be as close as physically possible to EnerPHit standard. So if you are interested in joining the community, contact the group to find out more.
