I’m old enough to be reminded about the TV show Mork and Mindy, where Mork(Robin Williams) arrived on Earth in an Egg shaped spaceship.
Mork would feel quite comfortable in this home.
As for me I’m not to sure about sleeping on that bed ‘shelf’.
This transportable unit called “BLOB VB3″, was designed by Belgian architectural firm dmvA.
I found these and additional photos at the Home-Reviews.com website.

Did you know there are two safety devices in your electricity cabinet to keep you safe?
Safety Switches
Safety switches were originally known as Earth Leakage Circuit Breakers (ELCB) but are now more commonly Residual Current Devices (RCD)
These super fast switches (less than 1/20th of a second) cuts the power off the instant a fault has been detected to protect you from serious electrocution.
RCDs generally control several individual circuits.
The RCD checks the incoming and outgoing current at your switch board. If the current isn’t balanced a person may be getting an electrical shock. The RCD’s are designed to disconnect quickly enough to minimise the risk of death’ or serious injury .
A RCD will always have test button’ like the units below, which should be regularly (monthly) pressed to check that it is working.
In a previous post on Lighting Levels I talked about using lumens to plan lighting. . . . . but which type of bulb should you use?
There are now 3 types of bulbs in common use
Halogen (A more efficient version of the old incandescent light bulbs)
Compact Fluorescent Lamp (CFL)
Light Emitting Diode (LED)
Light Output
Typical values of light output are:
Halogen – 15 Lumens/watt of power
CFL – 54 Lumens/watt of power
LED – 90 lumens/watt of power
Actual values will vary from manufacturer and also depending on the colour temperature of the light.
From the above figure it can be seen that a LED provides a significant power saving, even compared with a CFL.
Initial Cost
For an output of around 450 lumens enough for something like a desk lamp you can expect to pay:
Halogen – $3
CFL – $6
LED – $20
Bulb Life
Halogen – 2,500 hours
CFL – 10,000 hours
LED – 50,000 hours
The long life of LEDs meant that though the initial cost of $20 seems expensive over the life of the bulb you would have needed 5 CFL bulbs ($30) or 20 Halogen bulbs ($60)
Other Issues
CFL lamps do contain a small amount of the toxic element mercury, and do take several seconds to Warm up to full brightness.
Both halogen and CFL lamps tend to have limited durability if subject to vibration or rough handling.
A dimmable LED is around 40% more expensive than a basic LED.
If you are Building On Clay that is dry there is a risk of Soil Heave.
This is due to expansion of the clay if the moisture level increases with particular risk factors being:
Building after a long period of very dry weather when large cracks in the surface are visible.
Knock down and rebuild projects where there is a risk that part of the new foundations are on drier land than other parts.
Where there are trees, or trees have recently been removed.
To minimise the risk there is often an Engineers requirement to pre-wet the site to stabilise the moisture content.
Pre-Wetting Requirement
A typical requirement is to run sprinklers for 2 hours a day for 8-10 days which should increase the soil moisture to a depth of approx 1m.
Then the fill/construction pad below the slab should be laid within 2-3 days,
You are aiming for the equivalent of 20-25 mm of rainfall a day (20-25L/m2) The intention is on each day to thoroughly wet the top layer of soil and fill all the cracks with water without actually waterlogging the site.
For maximum effect the best time to do the pre-wetting is the late evening to minimise evaporation.
I have hear of builders saying the pre-wetting isn’t needed. Don’t accept this without soil moisture tests that have been accepted by the engineer who made the original requirement.
Effectiveness of Pre-Wetting
Although pre-wetting will minimise the risk of Soil Heave
It doesn’t mean that good foundation design can be neglected.
Letting the site moisture content stabilise through a winter, after removal of buildings/trees, is likely to be more effective.
