If you change the angles of the garden and used maybe two arches to enter/exit a seating/resting/other space partway along, I don't think it'd feel telescopic.
If you looked one arch in the middle of the garden directing the eye to the shed I agree that'd be telescopic!
Cutting the garden into zones, changing the angles/shapes, adding gravelled/chipped area, stepping stones, etc are all very low skill. The first two only require a spade really in terms of budget. The last two can be done inexpensively - slate chipping is inexpensive as it's a waste product from slate industry and comes in different colours (green, blue, plum, black, grey - or you can mix a combination). Other stones can be inexpensive.
You can get reclaimed paving stones or inexpensive ones to lay stepping stones within a gravel zone or to lead from one zone to the next. Which is a lower materials costs than paving a whole area or paying someone to pave.
Then plants, trellis, bamboo screens for your zones. Paint for the shed (a dark colour will make it recede from view, a light colour will make it feel closer).
And there are pages upon pages free online giving ideas on how to change the zoning/flow of your particular garden to make your idea work best.
