Don't forget to consider diversity if you're adding an extra bathroom. No need to spec the system to supply all appliances at once, as chances are they won't all be used at the same time.

am i too old for this but i thought head was from water level not bottom of tank preausre is basically the weight of water above a point (if you realy want to be technical its the gravity thats acting on it) therefore its taken from the higher point

The tap would be subject to 1.5bar when the cistern is full, as it empties half way, it would still have 1 bar of pressure being exerted on it.You need to measure the head from the lowest point of the cistern. Suppose you had the 10m deep cistern as above and had a tap that required 1 bar 5m below it. If there was a large draw off the tap would stop working when the cistern was half empty.

Actually, just re-read what you've said and I see the point you're trying to make! D'oh! For the case of designing a system, assume pressure from the bottom of the cistern as you can't guarantee the cistern will always be full! Not that your likely to find a cistern deep enough in a domestic property for it to make a noticeable difference!
If you're designing systems to that close a tolerance you're asking for trouble anyway.
