Conversions

What does an irregular-shaped house mean for the costs of an open plan conversion?

We are looking at buying a semi-detached house built around the 1930s. The house has a slightly irregular shape - the two side walls are not parallel, so the house is 1m or so wider at the back than the front. We want to remove two perpendicular internal load-bearing walls (~3m each) that currently separate the kitchen from the reception and the hallway (which may require a pillar). This will create an open plan kitchen-diner, and we will use part of the old kitchen space to create a downstairs bathroom. My question is what might be a ballpark range of costs for the structural work (removing walls and doorways etc.)? And what extra costs does the irregularity of the building add to the cost? I'm concerned that costs of RSJs and structural engineering fees could spiral if the shape adds complexity. Any advice gratefully received!
