Who this guide is for
- Homeowners planning a combined kitchen-living room
- People opening up separate rooms
- Anyone zoning a multi-use volume
- Those briefing an architect or designer
Zone the functions
Even in one volume, cooking, dining and lounging each need a defined zone so the space feels ordered. Zoning gives each activity its place without walls.
Decide where each function sits and how the zones relate before detailing the space.
- Define cooking, dining and lounging zones
- Give each activity its place
- Relate the zones to each other
- Order the volume without walls
Plan flow and circulation
How people move through the space, and whether through-traffic crosses the cooking zone, strongly affects how comfortable it is. Clear circulation keeps the zones from colliding.
Plan routes so the kitchen work area is not a thoroughfare.
Manage sightlines and noise
In an open volume, what you see and hear from each zone matters. Thoughtful sightlines can connect the space pleasantly, while noise from the kitchen can intrude on relaxing areas if not considered.
Plan for acoustics and views so the combined space works for everyone in it.
- Plan pleasant sightlines
- Consider noise from the kitchen
- Protect relaxing zones from clatter
- Connect the space without chaos
Light, services and structure
A large multi-use volume needs lighting and services planned for each zone, and opening up rooms can involve structure. These are key planning considerations.
Route services and any structural work to qualified professionals as the plan develops.

Common mistakes to avoid
- Failing to zone the functions within the volume
- Letting through-traffic cross the cooking area
- Ignoring noise intruding on relaxing zones
- Overlooking sightlines across the space
- Lighting the volume as one undifferentiated room
- Treating opening-up as non-structural
When to involve a professional
- A qualified professional should confirm services and structure

Frequently asked questions
Questions readers ask about this topic
How do I zone an open-plan kitchen-living space?
Give cooking, dining and lounging each a defined place within the volume and plan how the zones relate, so the space feels ordered without walls. Zoning, flow, sightlines and noise are the levers that make one big room comfortable for several uses.
How do I stop the kitchen noise intruding?
Plan the layout and acoustics so noise from the cooking zone does not dominate relaxing areas, and consider how zones are positioned relative to each other. Managing sightlines and noise is central to a comfortable combined space.
Does opening up rooms involve structure?
It can. Combining separate rooms into one volume may involve structural elements, which must be assessed and carried out by qualified professionals. Use the planning stage for zoning, then route structural work to qualified trades.
How is this different from a kitchen remodel?
This takes an architectural view of zoning a combined kitchen-living volume, focusing on flow, sightlines and noise across the whole space, whereas a kitchen remodel concentrates on the kitchen itself. The two complement each other.
