Open Plan vs. Separate Rooms: What Works Best for Extensions?

You're planning an extension, and one question keeps surfacing: should you knock through and go open-plan, or keep things traditional with separate rooms? It's not just about following trends. This decision affects how you'll use your home every single day for decades to come.

After 13 years of building extensions in Hull, we've seen both approaches work brilliantly and occasionally fail spectacularly. The difference usually comes down to understanding what you actually need versus what looks good in magazines.

The Open Plan Appeal

Open plan living has dominated UK home extensions for good reason. Combining your kitchen, dining, and living areas creates a space that feels significantly larger than the sum of its parts. Light flows freely, sightlines open up, and suddenly your home breathes differently.

For families with young children, open-plan is genuinely practical. You can cook dinner while keeping an eye on homework or toddlers playing. Nobody's isolated in the kitchen whilst everyone else enjoys the comfortable seating. The social hub of your home becomes genuinely social.

When Separate Rooms Win

Here's what the magazines don't tell you: open plan isn't always the answer. Some households function better with defined spaces, and there's no shame in that.

If you work from home regularly, a separate room with a door provides essential boundaries. Video calls become easier, concentration improves, and you can mentally "leave" work at the end of the day. An open plan extension with a desk in the corner rarely delivers the same separation.

Noise matters more than most people anticipate. Teenagers listening to music, younger kids playing loudly, television competing with kitchen sounds. It all happens simultaneously in open-plan spaces. If your household has conflicting schedules or different tolerance levels for background noise, separate rooms offer genuine relief.

The Hybrid Approach

Most successful extensions we build don't choose one extreme. Instead, they use flexible solutions that adapt to different situations.

Sliding or bi-fold doors between spaces give you both options. Open them for everyday family life and casual entertaining. Close them when you need quiet, privacy, or temperature control. We've installed countless room dividers over the years, and clients consistently tell us this flexibility was worth the extra investment.

Partial walls, peninsulas, or changes in floor level can define zones without completely separating them. You maintain the light and flow of open-plan whilst creating psychological boundaries that help organise how the space functions.

Practical Considerations for Hull Properties

Victorian and Edwardian homes around Hull weren't designed with open plan in mind. Original room proportions often work better when respected rather than completely reconfigured.

Structural requirements affect your options, too. Load-bearing walls need RSJs (steel beams) to be removed safely, which adds cost and sometimes creates awkward beam lines across ceilings. Sometimes the house itself tells you which approach makes more sense simply by where the structure sits.

Period features deserve consideration. If your home has original fireplaces, cornicing, or proportions worth preserving, forcing open plan can destroy character you can't recreate.

Heating and Acoustics

Open-plan extensions cost more to heat. You're warming a larger volume, and heat doesn't stay where you need it. A separate room retains warmth more efficiently, which matters during Hull winters.

Sound travels freely in open-plan spaces. Kitchen extraction fans, dishwashers, washing machines, televisions, they all compete for attention. Hard surfaces popular in modern kitchens (tiles, concrete, glass) reflect sound rather than absorbing it, making the issue worse.

How Your Family Actually Lives

Watch how your household uses existing space before deciding. Do people naturally gravitate together, or do they seek separate areas? Do you have multiple activities happening simultaneously that conflict, or does everyone do similar things at the same time?

Consider your stage of life, too. Young children benefit from an open plan where supervision is easier. Teenagers often need their own space and don't want to be under constant observation. Think five or ten years ahead as well. Your extension will outlast temporary phases.

Making Your Decision

There's no universally correct answer. The best layout depends entirely on how your family lives, your property's characteristics, and what you genuinely need rather than what's currently fashionable.
