“Gwernen” (Welsh) - Alder

Alder trees indicate wet ground conditions and they do best in cool damp soil. Alder wood is resistant to rotting in water.Gwernen is a unique wet room/WC and is perfect for private gardens, allotments and camping sites. It complements many of our designs for glamping pods and cabins. It is inexpensive and easy to erect and the perfect solution for an individual toilet/shower block in camping and glamping sites. It can be both off grid or connected to main services. 

Product Details

Inspired by the flames of a fire, a lattice of Welsh larch leaps into the sky and wraps around the Tŷ Tân. The individual cladding boards are fastened together by hand-forged metal brackets created by a local artist, who also forged the entrance steps and door ironmongery.


The door frame incorporates a convex glass panel following the organic shape of the structure.


The low headroom door forces the visitor to crouch slightly when entering the inner chamber, creating therefore a sense of accessing a private sphere.


Once inside the ovoid capsule is lined in birch ply and natural materials and the floor is covered with linoleum, which is a natural flooring made of linseed oil, pine resin and wood flour.


A skylight floods the space with natural light and allows for gazing at the night sky.


Like a tabernacle Tŷ Tân offers sanctuary from the outside world, creating an intimate space from where to reflect, contemplate and worship nature.

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.

Glamping retreat with kitchen

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.

Insulated space for year-round stays


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. Radiant heating panels are standard but their use is minimal due to the air tightness and insulative properties of the SIPs.

Cozy and insulated glamping

Boot room

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 for outdoor enthusiasts


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. 

Home grown timber:

All of our cladding boards are home grown and cut to size at a local saw mill.


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.


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.

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. 


The large window is made up of polycarbonate, which is a material with high impact, weather and UV resistance.

Connection will be required to sewer or septic tank, cold water supply and single phase electricity supply. Alternatively for off-grid version with compost toilet, photovoltaic panels will need to be located remotely to the pod. A battery bank can be accommodated in the design. 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.
