Plans for the UK's first tiny house regenerative settlement in Sea Mills, Bristol.

Tiny House Community Bristol wants to develop the former ‘Matrix’ site in Sea Mills to help people access high quality, affordable, deeply sustainable new small homes that meet their needs within an intentional community.

Public Consultation

We want to consult with neighbours and local residents, the wider community and other stakeholders to help influence our emerging designs at this early stage. Your comments and views are important to us and will be carefully considered as we draw up more detailed proposals.

The first round of public consultation will run from 24 September – 8 October 2022. Further consultation will follow in November and December before we submit a planning application to Bristol City Council at the end of the year.

The Site


The proposed site at Sea Mills is made up of two areas of land on the former training centre known as ‘Matrix’. It was in the past used for construction skills training and is now looked after by residential guardians. Some of the open space has been looked after by neighbours under garden licenses with the Council. This area will continue to be a shared garden and food growing area in keeping with it's heritage. 

In 2020, Bristol City Council invited THCB to bid for the land, and have made us ‘preferred bidder’. Due to our values, ideas, approach and vision, we have been given the opportunity to develop these Matrix sites.

Existing site plan with the proposed area for potential development outlined in red.

The proposal is for:

  • Approximately 14 new homes

  • Accompanying communal facilities and

  • A shared garden.

We hope to include a small zero-waste / refill shop, co-
working space, a community kitchen, and a small event

The intention is to build around 10 homes on the north
site and 4 self-build tiny homes on the south site. It will predominantly be a mix of 1 and 2 bedrooms to help with the housing diversity of Sea Mills.
Both sites have very narrow roads leading to them, and due to access challenges, we are proposing a car-free development (with one parking space onsite for a fully accessible home). Alternative transport
proposals are being explored, including a car club scheme and secure manual and electric bicycle storage and charging.

Initial Site Layouts

North Site
The approach on the North site is to take down the existing buildings, retaining as much of the materials for reuse as we can, and re-build on the same footprints, with the same courtyard arrangement. Some of he new buildings will likely be a maximum of 1.5 storeys high.

South Site
The South site is currently a disused area of tarmac, which was formerly used as parking for the Matrix. It is surrounded by houses on all sides, has a narrow access.  Our plan is for it to be used for Self-Build or ‘Self-Finish’ homes which are smaller in scale. A communal building and food growing spaces are to be incorporated as part of this site.

Design Ideas

We have explored a design approach that responds to the local character, site constraints, sustainability and affordability ambitions, but we would like to hear your ideas.
Ideas so far:

  • The proposed 1.5 storey asymmetric roof shape comes from the surrounding houses.

  • The homes will have low eaves (gutter level) to all boundaries, with no windows facing outwards, so there will be no more overlooking to existing surrounding homes and gardens than at present.

  • The homes are being designed to reuse materials from the existing buildings.

  • Roofs face south to capture solar energy.

  • Rainwater will be collected and stored for use on site.

  • Plants will grow on structures connected to the homes.

  • Rooflights will provide light to the rear rooms (bathrooms and stairs).

  • Gardens and open spaces will be shared for growing food.

Have Your Say

We are keen to consult with and fully involve the community at each stage of the design process before finalising a proposal and submitting a planning application at the end of the year.
At this interactive exhibition you can drop-in to view and talk through the proposals with representatives of Tiny House Bristol Community and their design team and join in informal small group design discussions. Your feedback and comments will be welcomed and will help inform the ongoing design process.
Information about the scheme is also available:

  • To view at Sea Mills library

  • To download or print a copy at home

  • Or if you would like to request a printed copy of the consultation materials, please contact Avril Baker Consultancy at or on 0117 977 2002.


Feedback survey

We would like to hear what you think of the proposals so far. Please fill in a feedback form at one of our events or complete it online – link to survey


Further consultation

There will be plenty of opportunities to get involved over the coming months as the designs are developed and prepared for a planning submission.

Planned events include:

  • Saturday 15 October, from 2-4pm at the Methodist Church - follow up "You said, We did" event - showing how your feedback and ideas have informed the design

  • Saturday 12 November and Saturday 10 December 2022 from 2-4pm - Further consultation events, leading up to the planning application being submitted


THCB will also continue to attend various meetings and events in the community. We hope to attend
the Stoke Bishop and Sea Mills Ward Forum Meeting on Friday 7 October and the monthly Repair
Café sessions at the Methodist Church. We welcome any other suggestions and invitations. 

We are also hoping to have information up in Sea Mills Library throughout. 

We look forward to getting your feedback.
