Above all else.

We are 3173

We are a little bit different and deliberately so. Our name derives from the combined height in metres of the three tallest peaks in Northern Ireland, Scotland and England, the locations in which we are currently based.

3173 is an elevated position from which to view our work and help us see further into the future.
