Is it permissible to build an outbuilding for the purpose of a gym, shower and steam room at the end of a garden which then drains into a soakaway? No toilets will be added.
Shower water from outbuilding to soak away?

But the purpose of a grey water tank would be to recycle the used water, which if used on garden plants etc would surely have the same effect as draining into the soakaway?

Then where is it going to?
Grey water recycling in a domestic setting is where the water is filtered/disinfected etc and re-used for toilets, the washing machine or indeed garden use. But you need a bit of kit (£££s) to do it. It doesn't just drain into a hole and then that has a pipe outlet feeding a big tank to tap into.

As this outbuilding will be some 30m away from the main house, this would not be practical to have a grey water tank in that case. Sounds like the only option would then be to pipe the waste water all the way back down the garden to the public sewer. But at 30m the slope would be crazy.
Why crazy? Minimum gradient for 100mm pipe with a toilet at the end of it (and why you wouldn't put a toilet in your gym is beyond me unless it was just to avoid drainage back to the sewer) is 1 in 80. Even if you go for 1 in 50 to ensure positive flow that's still only 20 mm per metre so total drop of 600mm across 30 metres. Pretty much what I've had to do with a garage build (clay subsoil so BCO told me rainwater had to drain to sewer rather than soakaway, when I suggested adding a toilet he said 'as long as you put handwashing in there as well, crack on')
Ok noted. I just assumed without proper knowledge on the subject.
Arr. Well worth having a look at Building Regulations Approved Documents for guidance for the whole thing then- you don't have to do exactly what they say but if you do then your work will comply with the appropriate Regulations. Plus when you start talking to builders you'll know what they're talking about (and may be able to spot the charlatans by what they don't mention!)
Would this need building regs for an outbuilding?
Not necessarily- check here http://www.planningportal.gov.uk/permission/ - but even if you don't need Building Regs it still has to be constructed appropriately, the guidance stuff is quite good for details that could otherwise bite you in the bum later
