This would be sooooooo much easier for you if instead of laying out hoses and electrical cords, you'd take some house measurements, plot them on paper, and explore the walk layout problem on copies of the drawing. If you created that plan, too, it would make your issue easier to understand for anyone following the thread.

Per your second picture, you're definitely not going to want the walk approaching the house as shown ... creating a 6" skinny planting strip between walk and house. This would be neither useful or maintainable. Secondly, it's not a great idea to have the walk close to a wall for it's run, if it can be avoided. Thirdly, where the walk terminates as a landing for the stoop, it should be the full width of the space between wall and post, or it's going to cheapen the whole house look. For what amounts to very little cost additional you can place a walk that doesn't. Create the landing and then arrange the walk away from the house.

Another separate consideration of designing a walk is how it ties to other features such as stoop and drive. About 97% of the time this needs to happen at a 90* angle .... not some slanting angle. Occasionally a 45* angle is appropriate, depending on the surroundings and circumstances. But all the other angles are almost always out. It's not really any different than as with automotive intersections which always have the goal of connecting at 90*. Exceptions are usually due to someone's earlier error that is later too difficult or costly to fix. The angle is measured at the walk centerline, not its edges. Those might vary if curves, alignment issues or design "flourishes" are involved.

It's often the case that trees set off of the corners of house are an integral part of the foundation planting, helping a lot to frame the house and make it look integrated into the landscape ... as opposed to appearing naked, isolated and unprotected. The smaller the tree, the closer it can go to the house. The larger the tree, the farther away it must be placed. Before you commit to the walk, it'd be a good idea to seriously ponder what size trees might be desired and their probable or definite location determined ... so that a wrongly placed walk doesn't force you into making a bad "compromise" later on.
