William's Den - Inspired by kids loved by grown-ups

William's Den - Inspired by kids loved by grown-ups

A place where play is the most important part of every day.


Our Concept

William's Den is a new and exciting adventure attraction, giving children the chance to connect with nature and get active as they explore a custom designed complex that brings the great outdoors inside.

We are creating a unique environment, inside and out, where children can play, explore, run, climb, build dens and learn, all in an open, rural and natural setting with a range of facilities tailored to families.

William's Den will be a place where children can run wild and explore to their hearts content - and we've even thought of the grown ups too, with plenty of space for everyone to relax and enjoy the day together.

Our Proposal

To develop a unique visitor attraction for fun family adventures in a beautiful countryside location.

We will create a bespoke indoor play area for children of all ages complete with sensory play zone, bridges, tunnels and climbing nets. This will be linked to an expansive outdoor play zone including trees, water play, discovery zones, unique play structures, den making materials and space to just run free.

William's Den offers something unique for visitors of all ages, with areas to relax and enjoy a coffee, try our delicious homemade food or have a rummage through the many treats and surprises in our onsite shop.

William’s Den names Hull Children’s University as official charity

William’s Den, the children’s play adventure near North Cave which is opening soon, has chosen The Children’s University as its official charity partner for 2017.

Hull Children’s University is working closely with Hull City of Culture 2017 on its legacy, encourages 5-14 year olds to try new experiences, develop new interests and acquire new skills.

Believed to be the UK’s largest-ever indoor timber play experience, William’s Den is described by owners Christian and Tor Carver as a ‘nostalgic nod to a bygone era of child’s play’.

Rosanna James from Hull Children’s University comments: “Children can only aspire to what they know exists and celebrating learning is at the heart of everything we do. We’re delighted to be working with William’s Den to offer some really exciting days out for local children in 2017.”

Tor Carver, co-founder at William’s Den, says: “Each year we will be selecting an appropriate charity partner at William’s Den and the work of Hull Children’s University is just amazing. With 2017 being the year of our launch, we wanted to work with a charity to help those in need locally. We’re looking forward to helping with the fundraising efforts this year.”

William’s Den includes a 475sqm play barn and outdoor play spanning over 10,000 m2 - including a 50metre zip wire, den making area and ‘mountains and molehills’ space for kids to run, jump and roll around freely.

William’s Den will also have an indoor play adventure including a stream, rainmaker water cascade, unique climbing structures, nets, treehouse and bridges.

Families will also enjoy a stunning restaurant serving wood fired pizzas in a lovingly restored brick barn, with an ice cream parlour and barista served coffees. A free play area for toddlers will be accessible from the coffee zone.

  • About our plans

  • What will William's Den look like? How will it fit in with its rural setting?

    Castle Farm, the location for William's Den, is a steading which included a range of traditional and modern farm buildings, as well as a Grade II farm house. This listed building will not be materially altered by the development.

    The work is taking place to the rear (east) of the project site and has involved the removal of three portal-framed agricultural stores which are being replaced by a new purpose built building which will house an indoor children's play barn.

    In accordance with the values of William's Den, we are using natural, sustainable materials wherever possible.

  • Will William's Den be good for the local area?

    In opening William's Den we will be giving work to local suppliers and creating up to 15 new jobs which we believe will have a very positive impact on the local economy. We are working hard to create a high quality new space, sympathetic to its surroundings, where families can enjoy quality time together and children can connect with nature.

  • How much impact will the development have on traffic levels in the area?

    There will be some additional road usage as a result of William's Den and cars will be able to use a number of approach routes, avoiding any significant impact on one particular road.

    We are also applying for a new and well signposted entrance to the attraction, with a long access road running adjacent to the existing road. This will minimize the possibility of hold-ups near the site itself, therefore we do not expect to create any inconvenience for local residents.

    A thorough report on all traffic-related matters has been included within our planning application and can be viewed on the East Riding of Yorkshire planning portal.

    As an overview, we anticipate approximately 200 vehicles visiting the site on a busy day, spread throughout opening hours, and these movements will be spread in four directions ie east / west on the B1230 and north / south on the A1034.

  • Why have you chosen to use agricultural land?

    While William's Den will occupy some land that has previously been used for arable production, the development of this type of family orientated tourist attraction will help to bring people closer to the countryside and encourage greater appreciation of our rural environment. The loss of a very small amount of farmland will however help to foster a wider understanding of the environment and the role the countryside plays in people's day-to-day lives. It is also known that many people connected to Britain's farming industry have chosen to seek worthwhile diversification projects, often introducing new retail and tourism outlets that have become a welcome addition to their geographical area.

    We see William's Den as an exciting, engaging diversification project which will enable a lot of children with limited access of the countryside to experience it at firsthand.

  • Will agricultural activity still take place in the fields around the site?

    There will be no intensive agricultural activity taking place around William's Den and no use of agrichemicals. The site will be surrounded by managed grassland. There will be no agricultural machinery stored at William's Den and when working in adjacent fields, tractor drivers will use entrances and exits well away from where children are playing.

    All fields surrounding William's Den are under the same ownership as the development site so there will be no conflict of interest.

  • Why did you decide to build William's Den here?

    We believe East Yorkshire is crying out for a new family visitor destination. Yes, there is the seaside and fun-fairs, but there is precious little in the way of traditional, wholesome family fun, especially for the very young.

    This will be a great opportunity for people living in the centre of Hull, Grimsby, York, Leeds and elsewhere to leave their towns and cities and enjoy a trip into the picturesque English countryside, and hopefully visit other nearby attractions and businesses during their trip, bringing more money into the local economy.
