DIOGEN PROJECT

This semi-suspended cabin mimics the structure of a bridge, however also facilitating a feasible structure by having concrete footing as the foundation for the timber glulam structure, as well as the timber structure sitting on two concrete beams which are anchored to the surrounding brick walls. To ensure the structure is stable in extreme weather conditions, it was decided that the structure would be placed under one of the brick arches whilst also having steel tension cables anchored to the brick walls; and thus ensuring the structure of the cabin remains intact.

CABIN/LIVING SPACE

As this is an off grid cabin, water and ventilation systems were an important factor in the design of the cabin. Both the fresh water tank and septic tanks are on top of the brick archway in the same latitude as the cabin. The pipes descend to the cabin carrying the water to and from the cabin, with the grey water being recycled and filtered via the septic tank.

This semi-suspended off grid cabin is designed with the idea of being elevated and creating the feeling off living on a bridge. This design idea was chosen as this is an off grid cabin, the suspended structure would mean it is unteathered from the earth (in this case, the structure does contain concrete footings, however the cabin is still elevated), and therefore would imply that it is off-grid in both a physical and hyperthetical sense.

The overall structure of the building is designed so that it can be assembled with ease, with the timber posts containing slots for the timber beams. The beams need to be slotted into the posts and then screwed to the concrete beams lying beneath the structure as well as the concrete footing.

The timber being used for the structure is glulam as it is can be easily procured, sustainable for the environment and structure and is a strong building material.

Project Key: 1. Solar Panels - On top of the brick archway and connected to the cabin via wires are 10 ‘250 Watt’ panels. The solar panels are placed at the top of the brick archway in order to maximise the cabins exposure to sunlight from the North, whilst allowing the cabin to remain under the archway and still recieve power from a renewable source. The solar panels contain a wire which descends to the solar battery on the south side of the cabin.

2. Fresh Water Tank - 8,000 litre fresh water tank which will store fresh water including harvesting rainwater. 2 pipes run from the water tank and descend down and fed into the cabin which will transport the water to the bathroom and kitchen sink.

3. Grey Water Tank - The water used in the bathroom and kitchen of the cabin will be sent down a pipe and pumped up to the grey water tank and recycled back into the fresh water tank.

4. Pipes - The pipes are 40mm in thickness and includes 40mm of insulation. The pipes run from the fresh water tank to the cabin.

5. Grey Water Pipes - The grey water pipes are for the water used in the cabin. The grey water will be pumped up through the pipes and into the tank above where it will be treated and recycled.

6. Tension Cables - Made out of Galvanised Steel Cables at 30mm thickness, the steel cables help the structure stay stable and spread out the load of the structure to the surrounding archway.

7. Boiler Tank - This allows for warm water to be available when inhabitants of the cabin need it.

8. Glulam Timber Beams (250mm by 80mm). Glulam Timber Beams were chosen as the beams are not only from a renewable source but are structurally reliable and relatively simple to construct.

9. Glazing - To allow natural lighting into the cabin.

10. Inverter - The inverter is placed next to the battery to convert into electricity for the cabin. Cables connect the inverter to the solar panels above which connect to the battery inside the cabin.

11. Composting Toilet - The composting toilet is often neccessary for off grid living although septic tanks can be used if using a flush toilet. However compost toilets are much easier to use as they dont require water and can be easily removed from the flap on the exterior walls.

12. Concrete Support Beams - To enhance the support of the structure, it was decided that the concrete beams attached to the conrete footings would be added to support the overall structure of the cabin, whilst also mimicing the structure of a suspended structure such as a bridge.

13. Concrete Footings - To support timber frame and structure.

14. Thermafleece Insulation - 150mm thick. This type of insulation does not require an additional vapour membrane or rigid insulation.

15. Breathable Membrane.

16. Sheathing Board - 10mm thickness. This was added to allow extra protection from damp and to attach timber cladding.

17. Timber Cladding (Internal and External) - 12mm thickness. Straight/deck cladding.

18. Battens (25mm by 50mm) - To bridge the outer outer plywood layer and inner layers.

19. Plywood Flooring (30mm thickness).
