Hi Mainie,
Our last house was a fan-shaped house. We had wooden floors upstairs and downstairs - semi-solid upstairs and laminate downstairs. We paid to get them fitted due to the irregular shape but there were no problems with the fitting. As a previous poster suggested, the fitter started at the straight wall (an internal wall) and worked towards the external wall. At the external wall there was a very narrow slither of flooring but it was extremely well done. We were delighted with it.
Unfortunately, I can't recommend the fitter as he has since passed away but we got the recommendation from Doors and Floors where we bought the floors.
Hope this helps, Triona
