London-based firm Neiheiser Argyros has completed Grid House, a renovation of a 1970s modern home in Evoia, Greece, which involved restoring the building to its concrete structure to create a series of simple living spaces.
Overlooking the Euboic Sea, the house was designed by Greek architect Nikos Hadjimichalis, and sits next to another recently renovated house by Neiheiser Argyros.
The structural frame of the house was originally stuffed, but Neiheiser Argyros sought to open up the building by showcasing its structural lattice and merging what were originally two separate apartments into one house with large windows and patio areas.
“The Grid House is about repetition and difference,” the practice said. “The simple, regular concrete structural grid creates a variety of indoor and outdoor spaces with views across the Euboic Sea.”
He continued, “The project is a comprehensive renovation of an existing modern home, creating a six-bedroom house tucked into the landscape, appearing unassuming from the entrance but opening its full width and height to the sea.”
To the north of the house, a new floating staircase connects the formerly separate floors, which now contain bedrooms on the ground floor and a large living, kitchen, dining and guest room on the first floor.
A landscaped garden with swimming pool and gradients towards the sea surrounds the house, overlooking an outdoor seating area protected by a concrete frame pergola.
A large paved patio area runs around the front of the house, with glass sliding doors giving the bedrooms on the ground floor direct access to the outside.
On the first floor, the living spaces are retracted and the structural grid is opened to create semi-covered porch spaces along the west side of the house, enclosed by slender steel columns and metal balustrades.
She described the practice “at times the lattice is infilled with brick to create an enclosure and privacy. At other moments it has full-height, timber-framed windows directing views out to the garden and sea”.
“In other locations,” she continued, “the lattice is left open and creates covered outdoor patios, porches, and pergolas.”
The exterior clapboard-marking concrete and brickwork is finished in gray paint, complemented by metal finishes for the balustrades and window and door frames.
Inside, the clean, modern details of the interior have been kept and complemented with the addition of colorful touches such as pink stair railings, wood joinery, furniture and marble worktops.
Neiheiser Argyros was founded in 2015 by Ryan Neiheiser and Xristina Argyros. Previous projects by the studio include a perforated metal pavilion in Greenwich, London, that hides exhaust manifolds in a tube station.
Elsewhere in Greece, Kapsimalis Architects built a monolithic house on the Greek island of Santorini designed as an arrangement of geometric shapes.
