There are plenty of amenities at Pipeline to draw the veterans as well as start-ups. The 14,000-square-foot space includes 25 private offices of various sizes, generous shared desk spaces, a lounge, a cafe, conference rooms, phone rooms, a kitchen, even a row of swings in front of a “garden wall” to take a break. “There’s a lot you can’t see such as plenty of soundproofing and special lighting. And the A/C — there are no hot spots or cold spots,” adds Oretsky.

Pipeline will seek a curated membership of several hundred people that is a mix of start-ups and professionals. Although the space is not set to open until later this month, the team has been signing people up steadily. Like the others, Pipeline plans to offer entrepreneurship-oriented workshops with speakers and social events like wine tastings, as well as discounts from local vendors.

Membership for shared space at Pipeline starts at $199, and private offices, some with sweeping bay views, start at $849. In between there are options for dedicated desks with lockable storage. Unlike some of the other spaces, Pipeline will be open 24/7.

“One of our most important strategies was to be on Brickell, a professional address in the urban core. We designed it with an eye to the professionals but also to be creative and energetic,” said Oretsky, a serial entrepreneur and lawyer. “We believe professionals and start-ups should come together. This is a way to get people plugged in, to get them to know the community,” he added. More Pipelines are in the plans.

Also betting on the Brickell area: Straat Investments, a holding company for several companies including .CO Internet. It is planning to open a co-working space next year, perhaps as soon as April, says Jose Ignacio Rasco, Straat’s managing director.

Straat bought a three-story building on Southwest 8th Street in the West Brickell area and is gutting and renovating the 16,000-square-foot space. Building — that’s the name of it — will be anchored by .CO Internet and other Straat companies, which will take up about a third of the space.

“It will be the new corporate headquarters with a co-working twist,” said Rasco. “We can be a start-up-tech community center, a rallying point for the community, rather than a typical co-working business model.”

Rasco said he looked for the right property and the right deal for two years. “What I loved is it is a warehouse style building and that’s how we are going to build it out.” In the plans — a rooftop garden.

RightSpace2Meet plans to open a 2,500-square-foot co-working space at the University of Miami Life Science & Technology Park in Miami’s Health District this month, joining its two other entrepreneur-focused co-working spaces in Coral Gables and in the Brickell area. The park itself is beginning to gain traction as a hub for tech and biotech — about 200 people attended the weekend-long AT&T Mobile App Hackathon that took place there in August, for instance — and a co-working space was always part of the plans. Just across the lobby from the co-working space, on the ground floor of the complex, is a new Balans restaurant; others are around the corner to keep the young and connected nourished.

The space itself features desks and tables, communal areas, bleacher seating and a treadmill. Monthly membership will start at $200 a month, with day rates available. Annette Reizburg of RightSpace2Meet, which is running the co-working space for the park, said as entrepreneurs outgrow the spaces, the park offers ample office options, including labs for science companies.

The co-working wave isn’t limited to Miami. The entrepreneurs behind the new 11,000-square-foot Caffeine Spaces, next to Florida Atlantic University and complete with a green screen podcast room, recently launched a crowdfunding campaign on Indiegogo for its furnishings. And while it may seem like a lot of spaces for one region, there are dozens of them in San Francisco, Seattle, New York and Austin, Texas, for instance.

“The catalyst to get the ecosystem to start spinning is more interaction, getting those people to talk, to start working in the same areas, exchanging ideas and thinking of stuff and starting stuff,“ said Juan Diego Calle, founder and CEO of .CO Internet. “We all need to be part of the solution — it is not about creating competition among co-working spaces. There are so many people interested in working together in the same place. That is the essence of it.”
