Architect Miguel Saraiva of Saraiva+Associados and interior designer Nini Andrade Silva have completed a renovation of The Furnas Boutique Hotel & Thermal Spa on Sao Miguel Island in the Azores archipelago off the coast of Portugal.

Operated by Discovery Hotel Management and a member of the international Design Hotels chain, the 55-key property now features a spa that comprises a thermal pool, fitness centre, 10 treatment rooms, whirlpools, flotation beds, Vichy showers and much more. The hot spring water, dubbed “iron water of quenturas” by locals, is pumped into the spa’s wet zone facilities at 56ºC, according to a spokesperson for Saraiva+Associados.

The design team had to rise to the challenge of maintaining the original character of the old Thermal Centre of Furnas, which became the hotel’s spa.

“We aimed to emphasise the beauty of the surrounding nature via a chromatic palette within the spa,” said the spokesperson. “We were also inspired by creating a journey through the historical, cultural and natural heritage of the island, so we used shades of white – symbolising the light of the vapours from the volcanic hot springs; brown to represent the strength of the earth; plus blues and greens that symbolise the influence of the Atlantic Ocean.

“The spa was designed with the main intention of providing customers with a way to relate to the surrounding natural resources,” continued the spokesperson. “For example, the materials and finishings selected for the interior are in shades of grey, white and neutral colours – in direct allusion to the volcanic rocks of Furnas.”

The hotel’s lobby acts as a multi-purpose space, designed to form a relaxed yet dynamic environment. For example, the market-style concept integrates the reception, bar, retail, work spaces, leisure and a restaurant – all in one hub.

Original pieces of art and other older furnishings have been sourced from the Azorean islands to give the interiors a sense of authenticity. The hotel is also filled with hundreds of candles.
