Go ahead. Grab a rough-hewn Adirondack chair, settle down on the expansively shaded deck under the pendulous greenery and bask in what may be the best public views — inside and out — anywhere along the water in downtown Miami.

This is, after all, your new museum of art — a $131 million haute-design showcase for modern and contemporary work that also manages to extend an open, dare we say homespun, welcome.

When it opens to the public at the edge of Biscayne Bay on Wednesday, on time and on budget, the strikingly original and meticulously thought-out Perez Art Museum Miami will put art front and center on the city’s landscape for the first time. In doing so, supporters and civic leaders fervently hope it will redefine Miami as a cultural destination.

With wrap-around verandas cooled by lush gardens and a monumental overhanging roof, 360-degree views of bay and city from within and without, and an adjacent new plaza, park and baywalk, the unusually porous museum could also become something else, backers say: a spectacular new front porch for the people of Miami.

“It’s going to be a Miami icon without trying to be anything other than a great museum,’’ said Terry Riley, the architect and former museum director who oversaw the launch of the building effort, in a recent public talk. “I think it’s going to be considered one of the most important contemporary museums anywhere.’’

Bold words, for sure, especially for a young institution that until relatively recently had but a small, uneven collection and a nearly invisible profile, thanks to its location behind fortress-like walls on an elevated plaza on Flagler Street.

During the new museum building’s long gestation, the use of scarce city park land and a public subsidy of $100 million (approved by voters in 2004 as part of a larger, $2.9 billion Miami-Dade County bond package) became a persistent target for critics, including some prominent local art collectors. So did the subsequent renaming of the onetime Miami Art Museum after developer Jorge Perez, whose $40 million gift of art and cash boosted its collection and bottom line but provoked raised eyebrows in the art world and a rift among the institution’s own supporters.

Against this backdrop, museum leaders say they were acutely aware of the need to avoid the cost overruns and construction issues that plagued the nearby Arsht Center even as they built a home and collection defined by high aspirations. PAMM officials say they’ve also nearly met a private fundraising goal of $120 million to supplement the public investment and create an endowment to support the expanded operation.

To design the building, Riley and board leaders picked the powerhouse Swiss firm Herzog & de Meuron, famed for the conversion of a massive London power plant into what is now the world’s most popular museum of contemporary art, the Tate Modern. More recently, the firm designed San Francisco’s de Young Museum, which is covered in punctured, oxidized copper and has a tower shaped like an inverted pyramid rising from Golden Gate Park. The firm, though known for its raw look and rigorous execution, has no signature style, which meant its approach would not be cookie-cutter, Riley said.
