This lookbook collects eight homes with spacious open-plan interiors, where different floor designs have been used to subtly define areas for cooking, dining and lounging.

Open-plan interiors are an enduring trend in residential design, used most commonly to blend kitchen and living spaces and create a social heart for the home.

However, this is now competing with an increase in homeowners opting for broken-plan layouts that cater to different activities and bring more variety to their interiors.

In this roundup, we explore the middle ground: open-plan rooms where mix-and-match flooring is used to softly demarcate kitchens, dining and living areas, visually reducing the size of the space without truncating it.

This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring discreet lifts, concrete bathrooms and non-boring beige home interiors.

Cas 8 House, Spain, by DG Arquitecto

A decorative range of mosaic tiles is used across the floors of Cas 8 House, a 1920s penthouse in Valencia that was recently modernised by local studio DG Arquitecto.

As part of the project, the studio created an open-plan living area with an integrated kitchen. Here, the tiles help to set apart zones for lounging and food preparation, without breaking up the room.

Hackney House, UK, by Applied Studio

Villarroel, Spain, by Raúl Sánchez Architects

This open-plan cooking, dining and sitting area in the Villarroel apartment is divided into two sections by the flooring, which marries grey-coloured stone slabs with warm wood.

This reflects architecture studio Raúl Sánchez Architects' overall design strategy for the home, which was to arrange it into zones without partition walls, opting for "material codes" that distinguish rooms from one another instead.

House Mellinet, Belgium, by Atelier Fréderic Louis

Architecture studio Atelier Fréderic Louis opted for a more subtle terrazzo for the floor in the kitchen of House Mellinet, which shares the same room as the dining area.

While the terrazzo gives a functional feel to the kitchen, the dining area adjacent has wooden parquet flooring that establishes a warmer and more intimate atmosphere more suited to gathering at the dinner table.

Nagatachō Apartment, Japan, by Adam Nathaniel Furman

Designer Adam Nathaniel Furman designed the colourful Nagatachō Apartment in Tokyo as a "visual feast", with open-plan rooms that are filled with an eclectic mix of colours, patterns and textures.

At the heart of the plan is a candy-pink kitchen suite, which is finished with watermelon-green vinyl flooring. It connects to a sitting room with a contrasting soft lilac carpet that "looks like icing".
