A resort-style terrace isn't built with lots of pieces, but with the right ones layered together: a textile base, the star furniture, and a couple of sculptural accents that give it personality.
Start with the floor: a natural-fiber rug defines the lounge area without closing it off, and works as a visual bridge between the furniture and the garden or the pool. On top of that base, two or three large pieces — a modular sofa, a pair of loungers — are enough to anchor the space.
The accents are what separate a pretty terrace from one with character: a jute pouf, small wooden sculptures, or a vase with local dried flowers. They are inexpensive details that can be rotated with the seasons without touching the base furniture.
Finally, let the greenery into the frame. A terrace surrounded by green never needs much more decoration.
