Mezzanine Design Ideas for Your Home

An intermediate mezzanine level can be a stylish way to add space and interest to an open-plan interior, says Emily Smith

Mezzanines are areas that sit above a larger, double-height room, typically overlooking the space below.

With open-plan living more popular than ever, these designs can offer a cosy, private zone or form a bright and airy gallery hallway to upstairs rooms.

Voluminous double-height structures lend themselves perfectly to this, which is why mezzanines are a popular feature in barns and other conversions. Houses with vaulted ceilings are another style that partners well, including designs that look to make the most of exposed structural frames.

But mezzanines can be great for creating useful compact areas, too – integrating a raised sleeping platform with storage space below is popular, for instance. The golden rule is to keep the mezzanine in proportion with the area beneath it – avoid covering more than 50%.

Consider how you intend to use the raised zone. Places with low ceiling height suit rooms with a cosy ambience, such as studies. But the key thing is to make sure there’s sufficient headroom, both in the mezzanine and in the room directly below – aim for enough to stand up without hitting your head on the ceiling, even if the area is being used as a sleeping platform.

In most cases, the structural fabric of the mezzanine remains exposed to the floor below, so material choice is important.

For instance, could metal beams and meshed balustrades bring an appealing industrial edge? The sense of connection between upper and lower spaces is crucial – a glass balustrade will help to blur boundaries, while a wooden rail could suit an exposed timber frame.

Think about how you want to physically connect the spaces – is there room to integrate a standard staircase? Alternatively, a spiral flight or a ladder will take up the least floor space and could become an eye-catching detail.

If you’re reworking an existing property planning permission is not generally required, but always check with your local authority.

Ripping out or adding new floors will alter the structural loads in your building, so consult a structural engineer to calculate what’s needed in terms of support. Always carefully plan heating, ventilation and lighting.

What type of property is best suited to this feature?

A double height space is always uplifting and a mezzanine will help to create a dramatic sense of volume.

If you’re building a new house, you can integrate the feature very early on in the design process, but you can also work this element into an existing structure by removing part of an upper-storey floor. These are popular additions to tall vaulted ceilings, but will make a great feature regardless of the overhead shape.

Eye-catching staircases work well to link a mezzanine with the floor below, but the right style will very much depend on the specific circumstances. Quirky, space-saving left-foot/right-foot paddle flights can be used if an alternative means of fire escape exists.

What’s the difference between a mezzanine and a gallery?

I suppose you could say the former is a space big enough to sleep or live in, whereas the latter might be narrower. However, I wouldn’t split hairs and both are used to describe a zone overlooking a double-height volume into a lower storey.

What are the main considerations when including a mezzanine?

Whether you’re building from scratch or integrating into an existing property, the key design factors are structure, height, light and drama.

Cost-wise, while a double-height space (without an intermediate floor) is cheaper than two floors in the same volume, because there is more wall to floor ratio the project will become more expensive than a single storey layout.

Remember this feature will decrease the total floor area across a two-storey house, but it will work to increase the drama and uniqueness of your property – mezzanines can even look great in smaller buildings. Most designs are fairly open-plan, exposed to the area it overlooks, but you can work to create privacy.

Incorporating screens (folding and or sliding) across the edge will enable you to shut off and open up a space as required; plus using sound absorbent materials will help to reduce noise from travelling between the storeys.
