Onnen
“Onnen” (Welsh) - Ash
The ash tree was thought to have medicinal and mystical properties and the wood was burned to ward off evil spirits. In Britain we regarded ash as a healing tree.
Our standard Onnen design comprises of a highly insulated core clad in local Welsh larch. It’s designed to be versatile, economical and contemporary and provide space ancillary to the main living quarters.
It is also ideal as a camping pod for paying guests on glamping and camping sites or holiday parks.
As part of our standard service, our architects will take care of any planning applications if required, so you do not have to worry when purchasing an Onnen. If you require changes to the standard internal configuration we will work with you in finding a bespoke solution that meets your needs.

DESIGN INSPIRATION - HIDDEN
“Helygen” (Welsh) - Willow
Nature is the leading inspiration for the Helygen®.
Natural materials, such as larch cladding, are utilised alongside modern materials to produce a design that balances concerns for the immediate and wider environment with the need for functional usage and aesthetic elegance.
The willow tree was the inspiration for the external cladding. As the tree ages the bark of the willow splits, producing an abstract lattice. The way in which light from the sun interacts with the swaying branches of the tree has also influenced the design. The sun casts beautiful shadows and alternative perspectives are created through which the beauty of nature can be appreciated.
The Helygen® is a responsive and intelligent structure, designed with functionality and versatility in mind so it blends easily within the environment. It sits comfortably in different settings, such as green pastures and woodlands and more built-up environments such as private gardens, towns and villages. It offers individuals, couples and groups privacy and comfort from where to contemplate and experience nature.
The tiny house movement, an architectural and social movement started in the USA, which advocates living simply in small spaces and promotes eco-friendly choices has also been a strong influence in the design of the Helygen®. Furthermore, Japanese architecture, traditionally typified by wooden structures raised off the ground and in particular Japanese micro-architecture, have heavily been a source of inspiration.

Kitchen
Natural light floods the kitchen thanks to floor to ceiling windows and a translucent ceiling.
Unlike many other pods on the market, our kitchen is not housed within the living space. Our hand crafted kitchen has the added benefit of being equipped with a double hob, ample storage and space for a fridge-freezer and oven. Radiant heating can be installed to effectively heat the space whilst in use.

SPACES - HIDDEN
Shower room
Perform your ablutions in style. A luxurious shower experience awaits.
The shower room also benefits from floor to ceiling windows and a translucent ceiling. The space can be effectively heated by the addition of a radiant heat source.
A wet room shower drains through a deck that seamlessly blends with the rest of the room.
The pedestal basin is located to allow optimum use of natural light.

Living/Bedroom
The central insulated core of the Helygen, which provides the main living and sleeping space, is constructed with structural insulated panels (SIPs). Structures built utilising SIPs typically have excellent insulation standards and lower running costs, compared to structures utilising alternative materials.
Depending on the size and configuration of the model chosen, the core is able to comfortably accommodate between two and four people. Thermostatic underfloor heating is standard but its use is minimal due to the air tightness and insulative properties of the SIPs.

The shower room and living/bedroom are accessed via the boot room. Dirty boots, muddy clothing and wet activity wear can be removed without having to soil the living space. Ample storage exists for spare bedding, suitcases and visiting pets.

Boot room
Veranda
On a wet day, views can be enjoyed from the veranda. To increase comfort and versatility of the Helygen, glazed sliding doors can be commissioned to enclose the veranda from the elements. The veranda can provide access to an open decked area that can be designed to suit the nature of the site. The decking can be used for barbecues and stargazing, with easy access via the veranda to the kitchen. The open-air decking area is for the whole family, with sufficient space to house an array of patio furniture and flora.
Trust, reputation and reliability are the hallmarks of our chosen local craftspeople. We made the decision to manufacture our pods in a dedicated facility in the heart of Wales, a stone’s throw away from our design studio. We are able to undertake regular site visits to ensure our delivery team on the ground have the support they need to exceed expectations.
Our use of quality components including birch plywood for the internal fittings, VELFAC windows and doors, Welsh larch cladding and the highly insulated core work together to deliver a durable, high-performance, and economical space.
The Onnen has been ergonomically designed with the process of delivery and assembly in mind. Our team will work with you to help ensure that site specific obstacles that could impact construction, delivery and assembly are carefully logged and assessed. Our processes have been streamlined to deliver ease, peace of mind and long-lasting value.
We have developed robust quality monitoring systems to ensure that the construction of our pods meets the high standards we have imposed on ourselves. These standards have been influenced by our professional training and experience, together with feedback from end users. We monitor our processes at regular intervals to ensure we learn from each stage of each and every build. Upon delivery, our team will undertake final checks to ensure the Onnen is assembled to agreed parameters.
Structurally Insulated Panels (SIPS):
The SIPS panels are used to create a core which is highly insulated, providing a comfortable thermal environment in all weather. Manufactured locally to our studio, we ensure minimal transport emissions and work closely with the manufacturer to provide quality assurance.
Welsh Larch:
All of our larch cladding boards are from the local area and cut to size at a local saw mill.
Steel:
The steel is sourced locally, and the manufacture of the base takes places close to our manufacturing site. This allows us to minimise emissions due to transport whilst working closely with the steel fabricator to provide quality assurance.
Birch ply:
We source all of our plywood from FSC certified manufacturers from Europe. Birch is native to Europe and is a renewable source of timber.
Birch ply offers excellent strength and durability with minimal defects.
Marmoleum:
Marmoleum has a very low carbon footprint. It is composed of 97% natural materials and uses 43% recycled materials.
Its natural bactericidal properties prevent micro-organisms such as Salmonella, MRSA and C Difficle from multiplying.
EPDM:
We source our EPDM for our roof coverings from the UK. EPDM has a low GWP (global warming potential) and can be reused and recycled into many different products. It has a life span of between 25-50 years and doesn't pollute rainwater so is an ideal material for rainwater harvesting.
Windows & doors:
All the windows and doors are supplied by Velfac, a Danish company. They are made up of mainly glass, wood and aluminium. The wood is FSC certified.
The windows and doors have a lifespan of at least 40 years, with Velfac providing a 12-year product warranty.
Heating:
The Onnen requires minimal heating due to its highly insulated core. Electric underfloor heating is included as standard in the core of all models but will only require minimal use.
No connections for drainage or water will be required.
Grid connection for electricity is possible, or alternatively a battery bank can be integrated into the pod with PV panels sited externally.
Foundations to be composed of a grid of four pads - loadings can be supplied on request.
Access board-walks and deck can be supplied to suit specifics of site.
