The greenest and most elegant new place in England
Little Haldens can become the greenest and most elegant new place in England. Crafted rigorously and with outstanding designers, engineers, landscape and ecology specialists to respect and honour its setting in the Gomm Valley, it will set a new benchmark for high-quality design, place-making, community participation and, in future, sustainable lifestyles and well-being.
Little Haldens will provide up to 1,000 new homes in a mixed-use community with a village square, family park and a beautifully regenerated valley.

The proposed development takes up less than 24% of the valley area and is concentrated in the southern and western parts; the building footprint is only 8% of the land area

‍We propose to create large new areas of species-rich chalk grassland, enlarge the local wildlife site, safeguard and better manage the ancient woodland and SSSI, plant nearly 5,000 new trees, extend the hedgerows, manage water run-off in a necklace of ponds, establish community gardens and local food-growing areas and reinforce green connections

There will be very significant net environmental gain from this scheme: using the government Defra matrix, the total biodiversity value for the valley will increase from 92.77 units pre-development (now), to 337.45 units post-development, a gain of 244.68 units.

There will be impacts on the local highways network but they are reasonable and manageable; we will invest in junction and highways improvements as well as in a local bus service, in electric vehicles, a car club and cycling. Little Haldens will be a pioneer of new, cleaner, safer, more environmentally-friendly movement and we will work closely with the county and district on network changes to enhance the experience of sustainable movement for all. Many millions of pounds will be provided under the Community Infrastructure Levy (CIL) to support improvements in infrastructure across the district.

The main street – a beautiful sinuous lane that will be the spine of the new place – has been designed at a gradient that allows for walking and cycling despite the steepness of the valley slopes. It helps make for a spectacular place to live, play and work.

The centre of Little Haldens will be a village square complete with primary school, nursery, fantastic local independent café and restaurant, shops, co-working spaces, a housing co-op , family park, community centre and, hopefully, health care provision.

We will offer a rich mix of homes for households of all kinds and circumstances. It will be an inclusive and accessible place. There will be flats and duplexes, small terraced rows, semis and detached homes all held to a code of elegant design and a site-wide material palette. 2o% of the homes will be on-off specials, 20% of them will have green roofs, and all will have fantastic access to open and green space.

A suite of proposals have been made for the long-term stewardship of the valley, the community and the estate. There will also be a Design Excellence Group with local stakeholders to work with the architects through the life of the scheme to help ensure that the design and quality of construction achieved hits or exceeds the ambition defined in the Development Brief and planning application. The construction of Little Haldens will see opportunities for local building firms and specialist contractors of all kinds.
Design and Access Statement
Human + Nature & Aviva Investors are delighted to announce that our outline planning application for Little Haldens in the Gomm Valley has been completed and submitted.

We understand and wholeheartedly welcome the responsibility that comes with making an elegant and sustainable new place that respects and indeed honours the valley setting. We greatly look forward to the continuing conversations with local people and organisations across Wycombe to help ensure the vision for the valley is fulfilled and indeed improved upon wherever possible.

You can download the full application here, including the Planning and Environmental Statements and the Design & Access Statement.  

You will be consulted on this application by Wycombe District Council and if you have any questions or comments for the promoters please write to

For those of you wishing to comment formally on the planning application you can do so via Wycombe District Council’s website. We will publish a link to the site as soon as we have one.



Thanks to all who gave up part of their Sunday (November 18) to visit the public exhibition on Little Haldens, Gomm Valley.

The exhibition showed the illustrative masterplan with the three principal character areas or ‘villages’ - Orchard, Hillside and Urban- the landscape plan, key features and ecology strategy, principal connections and streets, an overview of energy, water and waste proposals and some studies on possible design treatments and materials for the homes.

The plans will now be finalised and drawn together in an outline planning application for submission to Wycombe District Council in December.

We look forward to further constructive engagement and conversations to ensure this place honours the beautiful valley, meets housing demand effectively and creates an elegant and super-sustainable new settlement that will stand the test of time.

Previous Exhibition

The Gomm Valley Community Engagement & Design Event took place over the June 29 - 1 July weekend. It was held at the bottom of the Gomm Valley in the glorious sunshine.

There was excellent representation from the communities adjacent to the site (Pimms Grove, Cock Lane, Tylers Green, Hammersley Lane, Gomm Road and Micklefield) as well as people and organizations from across High Wycombe.

Human + Nature and Aviva were particularly pleased to welcome so many young people; they told us they were interested in the emphasis on design and innovation and the authentic commitment to sustainability, but also in the possibility of perhaps living in the Valley in the future given the likely choice in housing, the appeal of the village square and access to beautiful, open, green space.

People living close by were keen to understand how to connect the existing community to the new community to best effect and were understandably concerned to hear how we can act to minimise impact on the highways network. There was also a strong interest in the landscape and ecology of the valley and both the challenges and the opportunities that the development presents.

We were very pleased with the courtesy extended to our team by local people and organisations. We are in no doubt about the responsibility we have to study deeply, plan carefully, design imaginatively and consult widely to bring forward proposals that can rise to the challenge set by the Development Brief and indeed by our own values and vision. Please do not hesitate to get in touch with your further thoughts and questions.
