Countertop Basin Drainage and Lack of Space

[oAJAXo]

I'm planning a small bathroom and have decided to go for a counter-top hand basin.
The problem I have is space under the counter-top. The sink will be over a washer/dryer so I'm looking for advice on reducing the depth of the pipework under the counter. A washing machine is normally 85cms high. Counter-top 3cms. Basin 17Cms. That, plus some breathing space, is putting the top edge of the basin fairly high.
Can someone point me in the direction of a solution for reducing the depth of drainage pipework? Can the trap be further away with a flat pipe from the basin waste to the trap?
While the basin will only be for light use, it would be nice not to use a step ladder to wash our hands.
I'm not fitting this, I'm not a plumber. I'm looking to provide a solution before the professionals come round.

Many thanks .

[lets have a look]

You could get a 32mm bend one end fits onto the 32mm pipe the other end has a 1/14 nut that screws onto the basin slotted waste, then put an inline trap further down
