Check Google images for tiny house, small house, eco-house, pod, green living module or just a modern house. See anything you could imagine building very cheaply then living in?
Here’s the Original Twist idea of a simple modern looking house which, by using blocks or ICFs for the first floor and SIPs (structural insulated panels) on top, is quick and correspondingly cheap to make. It is also quite small which leaves something in the budget for all the latest mod cons like the home cinema, a nice car in the integrated garage and of course the eco kit – 24 solar panels and the heat pump pod in the garden.
The actual building is conventionally cubic, clad in vertical wood, with all the metallic looking curvy edges added on later. The edges conceal wires and pipes and are made of polystyrene or zinc covered forms. The upper south side is nearly all glass which adds to the feeling of space and allows for enough solar gain to take us into passivehause territory.
Small it may be but it is huge inside with the main living area 6m x 10m and a similarly massive room downstairs, both with cavernous ceilings. The raised bed platform gives a visual separation from the seating area and allows the big room to be a sitting room, bedroom and dining room all in one go. It will feel like a large expensive modern house but without the heavy price tag.
The main seating backs onto the big step and faces the partition wall which neatly houses a huge 4K TV, and all the usual kit, beneath a roller tapestry. This prefabricated wall incorporates storage on the reverse side and integrates all the gear for home automation, security and communications.

To convert the living space into a dining room the table comes up from the floor – (see magic table on http://www.originaltwist.com)…… the TV disappears, the bed tips up and away and the sofa glides back into the recess behind it; fanciful maybe but it makes excellent use of the space and easily accommodates large dinner parties. The sofa mechanism is quite simple with the sofa parking on top of the cover door when it is deployed.
With all the clutter cleared away there is plenty of room for partying with the ‘bar height’ raised platform making a safe place to put food and drinks. This house really is an entertaining machine.
There is a doorway either side of the big screen; one for the upstairs loo and the other to the kitchen. The generally high ceilings allow for an optional extra bedroom over the upstairs kitchen, accessed by a stairway along the back wall. It has to be very light and airy looking to preserve the cube like look of the main structure.
The house is suited to be built on a sloping site so access to the first floor would come from that level and ideally via a glass entry vestibule to the front door on the wall opposite the big glass south wall.

Conservatory, kitchen, bedroom, car - what else do you need?

Conservatory, kitchen, bedroom, car – what else do you need?

Downstairs the large breakfast room enjoys a wrap around conservatory and incorporates a second small integrated kitchen. Doors to the rear lead to an en-suite bedroom, a loo and the garage.
The daily grind won’t seem so bad when you start with a cuppa in bed watching the morning news then a shower (in the small shower-room on the bed level) before going downstairs to a sunny breakfast before nipping through to take your Porsche off to work.

Of course the eco-technomologicalness will be state of the art. The 24 Sunerg hybrid solar panels actually dictate the size and shape of the roof and the red trim panels are fixed directly to the panels (PV and wet solar are all 2m x 1m).  4 of the panels on the steep roof will be wet to give a massive 8sqm to feed my own twin tank heat bank design – my speciality. The other 20 panels use micro-inverters to give a nominal 6kWp and a real 2-3kW in the winter to run the little air source heat pump which also does some neat heat recovery from the house and uses some ground heated air too.  Batteries make a huge UPS which, combined with the batteries in the electric car, largely makes the mains supply more like a backup.

At the moment this is just an exploratory sketch but with serious intent. Local councils are being encouraged to make space available for self build houses and after a bit of polishing this design might gain some followers. Value for money would be very good if the drawings were all available and various trades all lined up and ready to make the next one. Practice makes perfect.
What next? Comments and criticisms would be good and then a list of the interested suppliers to put underneath here. If you are interested in owning one of these just let me know on the form and I’ll let you know how it develops.

Suppliers please step up:
Architects to draw it all up and polish the detail
Builders who like ICFs and SIPs
SIPs supplier (note the curvy roof)
Curved trim supplier – polystyrene.
Engineer for raising table and gliding sofa
TV partition wall
ASHP supplier
Solar pod for ASHP
Panels and micro-inverters
Power router
Panels – I’m set to import these.
Heat banks and energy design – that’s me.
