Open-Plan Living: Is It Right for Your Home?

June 2025·6 min read

Open-plan kitchen-diners are the most requested project we build. The idea of knocking through walls, flooding the ground floor with light, and creating a single flowing space for cooking, dining, and living is enormously appealing. But is it right for every home? Here's an honest look at the pros, cons, and practicalities.

The Case For Open-Plan

Natural light

Removing walls between the kitchen, dining room, and living room allows light to travel through the entire space. Add bifolding doors to the garden and the transformation is dramatic.

Family connection

Parents can cook while keeping an eye on children. Conversations flow naturally. No one is isolated in the kitchen while everyone else is in the living room.

Entertaining

An open-plan space is ideal for hosting. Guests can move freely between kitchen, dining, and living areas. The host isn't cut off from the party.

Property value

Open-plan ground floors are consistently cited by estate agents as one of the most desirable features for buyers. It's one of the safest investments you can make.

Sense of space

Even without extending, removing walls makes a home feel significantly larger. Combined with an extension, the effect is transformative.

The Case Against (Or: Things to Consider)

Noise travels

An open-plan space means cooking smells, TV noise, and kitchen clatter all share the same space. If you like quiet evenings in the living room while someone else cooks, a fully open plan may not suit you.

Heating costs

Larger open spaces cost more to heat. Good insulation and underfloor heating help, but it's worth factoring into your running costs.

Cooking smells

A good extractor fan is essential. Without one, cooking smells will permeate the entire living space.

Loss of defined zones

Some families prefer separate rooms for different activities. A semi-open plan — with a wide opening rather than full removal — can offer the best of both worlds.

How to Create an Open-Plan Space

1. Remove the wall

If the wall between your kitchen and dining room is load-bearing, we install a steel beam to carry the load above. If it's non-structural, removal is more straightforward.

2. Extend (optional)

Many clients combine wall removal with a rear extension to create a truly generous space. The extension adds the square footage; the wall removal creates the flow.

3. Add bifolding or sliding doors

Glass doors to the garden complete the open-plan feel — bringing the outside in and flooding the space with natural light.

4. Install a kitchen island

An island creates a natural boundary between the kitchen and living areas without closing the space off. It also adds prep space and casual seating.

5. Consider a lantern or rooflight

A glass lantern or flat roof window above the dining area creates a dramatic focal point and fills the centre of the space with natural light.
