Need ideas

Im looking to completely redo the downstairs of property but dont know the best way to use space. I need to see some pictures or something as i cant visualise things. I Want to make a larger kitchen/dining space, downstairs toilet, living area. possibility of utilising garge which is connected to house with roofed passageway from front to rear of property. This is down a step though, so not level floors. Attached photos are as i have bought the property. Open to removing/moving walls/doors etc. Thanks
