Neat hedges lend an English feel.

This new home exquisitely embodies age-old principles of symmetry and proportion, and the yard is no exception. Landscape architect Ron Holbrook chose a pretty parterre made of boxwood and yew hedging, pea-gravel pathways and a limestone fountain to bring a formal look to the backyard.

A sunken area offers up a different look at every turn.

Two large oak trees dictated the symmetrical design of this backyard.

A gravel area with bistro table is a casual spot to snack after a swim, with comfortable lounge chairs flanking each side of the pool. In the foreground, an upper terrace offers a more formal dining area for entertaining.
