Next in our series spotlighting residential architecture from each US state is Florida, where lavish waterfront villas designed for tropical living include a house built around its own lagoon and a home with a waterslide.

Casa Bahia by Alejandro Landes

This tropical-modernist mansion in Miami was the first architecture project by Colombian-Ecuadorian filmmaker Alejandro Landes, who built it for himself and his family in 2015, but put it up for sale six months later for $50 million (£40.1 million).

The 20,000-square-foot (1,858-square-metre) estate on the shore of Biscayne Bay includes seven bedrooms distributed across three storeys, and was envisioned as a "framework for living".

4567 Pine Tree Drive by Studio MK27

Brazilian architect Marcio Kogan of Studio MK27 designed this luxurious Miami Beach residence, featuring a private lagoon where residents can swim with fish, and a bridge walkway that snakes over the top.

Measuring 100 by 30 feet (30 by nine metres), the manmade lagoon is organically filtered and surrounded by vegetation to provide an "authentically manicured" natural environment for the Florida home, which also features interiors by Jader Almeida and Artefacto.

Villa Allegra by Oppenheim Architecture

Miami studio Oppenheim Architecture overhauled a local house to allow residents to divide their time between indoors and out.

The 9,000-square-foot (836-square-metre) Villa Allegra was adapted from a "nondescript, one-storey home" according to the architects, who added an extra floor and created partially enclosed areas to maximise the potential for outdoor living.

Pine Tree House by SAOTA

South African firm SAOTA's first project in Miami Beach is an expansive family home in the historic Collins Waterfront district that boasts a basketball court and a waterslide.

Composed of rectilinear volumes and floating planes, the two-storey home is meant to feel expansive and fluid – taking indoor-outdoor living to the extreme.

Brillhart Residence by Brillhart Architecture

Husband-and-wife duo Jacob and Melissa Brillhart completed this home fronted by slatted wooden shutters in a lush Miami forest for themselves to live in.

They wanted the single-storey building to "reflect a new architecture for the tropics", and took cues from local construction techniques and materials during the design process.
