In the living area of a Brazilian beachfront home originally designed by Marcio Kogan of Studio MK27, with recently updated interiors by architect Sig Bergamin, a large Luiz Áquila abstraction mounted above the fireplace is flanked by a Mariana Palma painting and a group of four works by Julio Le Parc. Bergamin anchored the room with a pair of Patrick E. Naggar sofas, their curves echoed in cocktail tables by Vladimir Kagan, who also conceived the angled floor lamps.

The pool terrace has enviable views overlooking Iporanga Beach.

Beneath the floating staircase, a vivid abstraction and a parrot painting, both by Claudio Tozzi, are displayed next to works by Emiliano Di Cavalcanti and Cícero Dias.

In the stair hall, a Tomie Ohtake canvas hangs above a console that hosts a Murano glass vessel by Fabio Maria Micucci.

Oty Light pendants descend above the dining table, which is surrounded by a suite of caned chairs by Claudia Moreira Salles.

A kaleidoscopic Sarah Morris painting makes a spirited statement at the base of the staircase.

An Alfredo Ceschiatti bronze nude reclines on the pool terrace.

Centered over the bed in the primary bedroom is a painting by Alfredo Volpi, while the work on the nightstand at right is by Clóvis Graciano.

In the primary bedroom, Henri Matisse–inspired works by Vik Muniz hang next to a Seguso lamp and armchairs by Claudia Moreira Salles.

A bronze figure by Sonia Ebling sits in a shady spot near the pool.
