Smart homes and sustainable materials: where interior design is heading in 2027

Arch. Katerina TanevaUpdated November 20264 min read
In short

The future of interior design lies in homes that are smart but don't look “technological”, and in materials that last a long time and don't harm nature. In practice this means controlling lighting, blinds and climate from your phone or by voice, energy-efficient LED lighting and good insulation, natural and recycled materials, and furniture that is repaired rather than thrown away. All of this is planned at the design stage – cables and installations are laid during the rough works.

Ten years ago a “smart home” meant complicated panels on the walls and technology on display. Today it is the opposite – the best technology is the kind you don't see. The same is happening with sustainability: it is not about an eco look but about sensible decisions that make the home healthier, more economical and longer-lasting.

The smart home without visible technology

In 2027 the smart home is controlled with ordinary switches, a phone app or by voice. What matters is that the system works intuitively for everyone in the family – including children and guests.

What can be automated at home

  • Lighting – “day”, “evening”, “cinema” and “night” scenes, dimming and automatic switching on with motion in the corridor.
  • Blinds and curtains – opening in the morning and closing in strong sun.
  • Climate and heating – different temperatures by room and by hour, remote control.
  • Security – video intercom, sensors for open windows, water leaks and smoke.
  • Energy – monitoring consumption and controlling appliances.
  • Audio – built-in ceiling speakers you can't see.

How to plan a smart home

  1. Decide what you want to control – not everything needs to be “smart”.
  2. Choose a system – wired (more reliable, for new builds and full renovations) or wireless (for finished homes).
  3. Include it in the design – the electrical installation, network and sensor positions are decided before the rough works.
  4. Plan space for the equipment – distribution board, router, server, good Wi-Fi coverage.
  5. Think about the future – spare conduits and cables cost little now and save a lot later.

That is why the smart home is part of the interior design project, not an add-on after the renovation. See also the right order of renovation stages.

Sustainable materials in the interior

A sustainable material is one that is produced responsibly, lasts a long time and does not release harmful substances into the home. The solutions we use more and more often:

MaterialWhy it is sustainable
Solid and veneered wood from certified forestsA renewable resource that can be sanded and refreshed
CorkHarvested without felling the tree, warm and sound-insulating
Clay and lime plastersNatural, “breathable”, regulate humidity
Reclaimed wood and terrazzoA second life for materials
Linen, wool, organic cottonNatural fibres that last for years
Low-VOC paints and adhesivesCleaner air at home
Sustainable interior materials – cork, reclaimed wood, linen and clay plaster
Natural materials are healthier and age beautifully.

Energy efficiency

  • LED lighting everywhere – lower consumption and a long life.
  • Good insulation and quality windows – the basis of everything.
  • Heat pumps and underfloor heating for an even temperature.
  • Blinds and curtains that prevent overheating in summer.
  • Efficient appliances and flow-limiting taps.

Natural light is the most sustainable solution.

Durability is the most sustainable solution

The most sustainable piece of furniture is the one that is never thrown away. That is why we encourage our clients to invest in quality where it matters: kitchen, wardrobes, flooring, bathroom. Custom furniture with good hardware lasts for decades, and when needed the fronts can be replaced without replacing the whole carcass.

“A sustainable home is not one that looks eco-friendly, but one that is used and loved for many years.” – Arch. Katerina Taneva

Frequently asked questions

Is it expensive to make my home smart?

It depends on the scope. Basic lighting and climate control is affordable, especially if it is planned during the renovation.

Can I have a smart home in a finished apartment?

Yes, with wireless systems. Wired systems are more reliable but require renovation.

Which flooring materials are most sustainable?

Oak parquet that can be sanded many times, cork and quality ceramic tiles.

Are sustainable materials more expensive?

Some are, but they last longer and are easier to maintain, so in the long run they are often better value.
