Bless you. Mine sits sideways to the street too, and my challenge is treating that side view as front.

Lowest budget things I can think of would be to paint the garage door same color as house and the rest of the garage. Pressure clean drive way. Paint the trim of your house - maybe medium green or white. The wooden fence is, I think a very good idea.

I love the suggestions your given about the structures to join the buildings. Such good ideas and I may use them myself for my back building.

If the chain link fence must stay for now, paint it black. (They do take paint well). Then hedge the fence or use a vine that does well in your area. Bouganvillia is a go-to here, bute grow something you can keep in nice form.

Definatly paint trim a white or complementary color that stands out, but not garage. Someone suggested a stronger color for the garage. Hmm. Maybe... If it were a deeper yellow of the same hue or a wood tone done well. I think until you settle on that though, paint the same coloer to minimize the standing our.

Wiindow boxes, edgings. Path accents, etc.

All the best.
