How Much Space Do You Need Before Choosing a House Share or Studio Flat?

Quick answer

A room in a house share must be at least 6.51 square metres for one adult under English HMO licensing rules, while a studio flat typically needs 25 to 30 square metres to comfortably fit sleeping, living and cooking areas. Measure your belongings, daily routine and storage needs before choosing. A house share gives you a private bedroom plus shared common areas, while a studio flat offers full privacy but requires clever use of every square foot.

UK legal minimum room sizes

Before you start measuring, it helps to know what counts as legal. In England, licensed Houses in Multiple Occupation (HMOs) must follow national minimum bedroom sizes set out in the Licensing of Houses in Multiple Occupation (Prescribed Description) (England) Order 2018:

• 6.51 square metres for one person aged over 10
• 10.22 square metres for two people aged over 10
• 4.64 square metres for one child under 10

Any room smaller than this must not be used as sleeping accommodation, and landlords cannot count communal space to make up the shortfall. Some local councils set higher minimums, so always check with the local authority if you are comparing house shares and studio flats to rent near me.

Studio flats are not covered by the same HMO licensing rules because they are self-contained dwellings. There is no single legal minimum size for an existing studio, but the Government's Nationally Described Space Standard recommends around 37 square metres for a new one-person, one-bedroom dwelling. In practice, most livable studios you will encounter on the open market fall between 25 and 30 square metres, with smaller bedsits sometimes dipping below that.

Checklist: does the room fit your belongings?

Rather than guessing, walk through your possessions and daily habits with a tape measure in hand. Use this checklist when viewing a room in a house share or a studio flat:

• Bed and bedding: a double bed needs roughly 3.4 square metres of floor space on its own, plus room to move around it.
• Wardrobe or chest of drawers: measure the depth and width. In a house share, check whether the room has a built-in wardrobe or if you must share a hallway cupboard.
• Desk or workspace: a standard desk is about 120 cm by 60 cm. If you work from home, this becomes essential, not optional.
• Luggage, sports gear or musical instruments: large items often decide whether a 7 square metre room feels cramped or comfortable.
• Kitchen storage (studio only): in a studio, your kitchen is your kitchen. Count the cupboards, check the fridge size and see whether there is room for weekly groceries.
• Bathroom: an ensuite adds privacy but eats into your floor plan. In a house share, check how many people share the bathroom and whether there is a separate WC.

Write down the numbers. A room that looks spacious in a wide-angle listing photo can feel very different once your suitcase and winter coat are inside it.

House share vs studio flat: space and privacy trade-offs

The real decision is rarely just about square metres. It is about how those square metres are divided between you and everyone else.

In a house share, your private space is usually just the bedroom. The kitchen, living room, bathroom and hallway belong to the whole household. This can work well if you spend most of your time out of the house, or if you enjoy cooking and socialising with flatmates. It can feel restrictive if you work from home, keep unusual hours or simply value quiet.

A studio flat puts every function under your control. You decide when the kitchen is used, how loud the music is and where the sofa goes. The trade-off is that everything happens in one room, so poor layout can make even a 30 square metre studio feel claustrophobic.

When weighing up house share vs studio flat space and privacy, think about your routine on a typical Tuesday evening, not just the viewing on a sunny Saturday afternoon.

Storage and daily routine considerations

Storage is where studio flats often lose out to house shares. A shared house usually has a loft, a garden shed or at least a larger hallway cupboard. In a studio, every box competes with your bed, your desk and your sanity.

Ask yourself:

• How often do I need to access out-of-season clothes or hobby equipment?
• Do I cook most evenings, or live on takeaways?
• Do I exercise at home, or use a gym?
• Do I have guests to stay, and if so, where would they sleep?

If your answers suggest you need room for a guest bed, a bike or a proper kitchen, a studio may force you into constant rearrangement. A house share with generous communal areas can absorb those needs more easily, as long as you are comfortable negotiating shared use.

For couples, the maths changes again. A double room in a house share must be at least 10.22 square metres by law, which is still smaller than most studios. Is a house share or studio flat better for living as a couple covers the specific trade-offs in more detail.

Questions to ask before viewing

Landlords and agents do not always volunteer room dimensions, so ask directly. Useful questions to ask before renting a room in a house share include:

• What are the exact dimensions of the bedroom, and can I see a floor plan?
• Is the room HMO-licensed, and what is the license number?
• How many people currently share the bathroom and kitchen?
• Is there any additional storage, such as a loft or shed?
• Are bills included, and does that cover internet suitable for working from home?

For a studio, add:

• What is the total floor area, and is the kitchen separate or within the main room?
• Is there a dedicated dining or workspace area?
• What is the EPC rating, and what are typical winter heating costs?

Always check the house share vs studio tenancy agreement before signing, particularly clauses about guests, subletting and how disputes over shared areas are handled.

A note for international students

If you are coming to the UK to study and are unfamiliar with the local rental market, the process can feel overwhelming. OK Living offers dedicated human concierge support for international students throughout the rental journey, with rental groups covering London, Hong Kong, Singapore, Sydney and Melbourne, and curated student accommodation near universities. This can be particularly helpful if you are trying to judge room sizes from listing photos before you arrive.

Decision summary

• Start with the legal minimums: 6.51 square metres for a single adult in an HMO, and around 25 to 30 square metres for a practical studio flat.
• Measure your actual belongings, not just your body.
• Think about your daily routine, not just the viewing.
• A house share trades private space for shared facilities and often lower rent.
• A studio flat trades shared facilities for full control of a smaller area.
• Ask for dimensions in writing and check the tenancy agreement carefully.

If you are still weighing up the overall cost, the broader comparison of house share vs studio flat looks at how rent, bills and lifestyle fit together beyond just square metres.

FAQ

Can a landlord legally let a bedroom smaller than 6.51 square metres?
In a licensed HMO in England, no. Any room below that size must not be used for sleeping by an adult. Local councils can set higher standards, and Scotland and Wales have their own HMO licensing rules, so check the rules that apply to your area.

Is there a legal minimum size for a studio flat?
Not for existing dwellings. The Nationally Described Space Standard recommends 37 square metres for a new one-person dwelling, but this is planning guidance rather than a blanket legal requirement for all rentals.

Does a studio flat count as an HMO?
Generally no. A studio flat occupied by a single person or a single household is a self-contained dwelling, not an HMO. HMO rules apply when three or more unrelated people share facilities.

How do I measure a room accurately during a viewing?
Bring a tape measure or use a phone app with augmented reality. Measure the longest wall and the shortest wall, then multiply. Subtract any built-in wardrobes or alcoves that cannot be used for furniture.

Should I prioritise an ensuite or more floor space?
It depends on how many people share the bathroom. In a house share of four or more, an ensuite can save significant time and stress. In a smaller household, or in a studio where every square metre counts, a shared bathroom often makes better use of the space.
