Scope
What this checklist covers
The preparation ground these prompts walk through.
- The service core, risers and bulkheads that any layout has to accept
- What has to be dealt with in the moment the front door opens
- Which activities are sharing a floor, and when they overlap
- Rules that belong to the building and to the people who manage it
- What can be kept above head height, and what has to stay easily reachable
- Condensation, ventilation and noise as they are experienced in a flat
Audience
Who this checklist is for
- Owners of a compact flat who want more from it without moving somewhere larger
- People who have recently taken on an apartment and are still learning how it behaves
- Households whose flat has to absorb home working alongside everything else
- Anyone preparing for a first conversation with a designer about a small apartment
Timing
When to use it
- Recording which features of the apartment are fixed points for any plan
- Describing how each room is genuinely used at different times of the day
- Gathering the building and ownership questions that need answering locally
- Preparing access information before anything large is ordered
- Listing the questions a small apartment raises that an owner cannot answer alone
Limits
When it is not sufficient
This is general planning preparation. These situations need a qualified professional, and often the relevant authority.
- Deciding whether any wall in the apartment can be altered or removed, which qualified professionals must assess
- Interpreting a lease, ownership document or building rule, which needs qualified advice on your particular situation
- Establishing what a building or a local authority would require before internal work in a flat, which must be confirmed for this address
- Diagnosing damp, condensation or ventilation problems, which belong with a qualified professional who can inspect them
- Settling positions for drainage, wiring or heating, which are for the relevant qualified trades to determine
The checklist
Work through the sections
Tick the boxes on paper or on screen — nothing is stored, so print the page if you want to keep your marks.
1.The parts of the apartment that arrived already decided
A flat carries the building inside it, and the pieces that belong to the building are the ones a plan has to work around.
Mark on a rough sketch where waste pipework appears to leave the kitchen and bathroom, and treat those points as fixed until a qualified professional says otherwise.
In apartments the drainage position quietly decides which rooms can hold water using fittings and which cannot.
Whether any drainage or soil connection can be altered in a flat is for a qualified professional to establish, not for an owner to assume.
Write down every boxed corner, bulkhead and dropped ceiling, and note whether it runs along a wall or crosses the room.
These enclosures usually hide services that other homes in the building depend on, so they are rarely as removable as they look.
Ask a qualified professional what sits inside any boxing before it is assumed to be empty or moveable.
Note which walls sound solid and which sound hollow when knocked, and record it as an observation to be checked rather than a conclusion.
This tells a professional where to look first, while keeping the judgement about what any wall does with the person qualified to make it.
Whether a wall plays a structural role or separates you from a neighbour must be established by qualified professionals.
Record where the consumer unit, water stopcock and any boiler or heat interface unit sit, and note what currently has to be kept clear in front of each.
These often occupy the one cupboard a small flat could otherwise use, and they cannot simply be built over.
What has to be left reachable around metering and isolating equipment is for the relevant qualified trade and the building manager to say.
Open each window to see whether it swings inward, and record how much of the floor or wall in front of it is taken out of use when it does.
Inward opening casements rule out furniture positions that look perfectly reasonable on a plan.
Photograph the ceiling in each room against a door frame so differences in height between rooms are recorded rather than remembered vaguely.
Height varies more between rooms in a flat than most owners expect, and it decides where tall storage can go.
2.Everything that has to be dealt with at the front door
In a small apartment the entrance is not a hall but a moment, and everything that arrives has to be dealt with in it.
Note which way the front door swings and what it sweeps as it opens, since in a flat this is usually the only door that cannot be rehung freely.
The arc behind an entrance door is often the only spare wall in the flat, and it is dead space if the door needs it.
Any change to a front door or its frame in an apartment is a matter for the building owner or manager and a qualified professional.
List everything that gets put down within a pace of the front door on an ordinary day, including keys, post, bags and shoes.
Naming the objects turns a vague wish for a tidy entrance into a storage requirement someone can design for.
Consider whether there is anywhere to rest a bag or a shopping load while unlocking or removing shoes, and note where that currently happens.
Where there is no surface within reach of the door, the floor of a small flat tends to become one.
Stand outside the open front door and write down what a visitor sees, particularly if it opens straight into the living area.
In flats the doorway view is shared with every delivery and visitor, which affects what can be stored in the open.
Record where parcels are left and how they travel from the building entrance into the flat, including anything that has to be unpacked at the door.
Packaging accumulates faster in apartments because there is rarely a garage or porch to absorb it.
List the bulky items with no settled home, such as a bicycle, a pushchair, a suitcase or a drying rack, and where each currently ends up.
These few objects usually cause most of the visible clutter, and they need naming before storage is designed.
Ask the building manager what may be kept in communal areas, since that is decided by the building rather than by the flat.
3.Rooms asked to carry more than one activity
Small apartments rarely have a spare room, so the honest question is which activities are sharing which floor and when.
Go room by room and set down what each one is asked to do and roughly when, including working, eating, drying laundry and exercising.
Seeing the list in one place shows which room is genuinely overloaded rather than which one merely feels untidy.
Identify the two activities that most often collide, such as a table needed for working and for eating in the same part of the day.
The collision, not the room size, is usually what makes a small flat feel unworkable.
Note what has to be cleared away before another use can start, and who in the household actually does the clearing.
Any arrangement that depends on daily clearing away needs a realistic view of whether that clearing will happen.
Consider whether any activity could move to a different room at a different time, and note what would have to exist there for that to work.
Relocating one activity often relieves a room more simply than rebuilding it, which is worth testing before anything is designed.
Decide which single use you would protect if a room could only keep one, and write that down as the priority for the space.
Designers can work with a stated priority, whereas an unspoken one gets negotiated away during design development.
Record how the flat absorbs an overnight guest, including where bedding is stored and which room stops being available.
Guest arrangements are the use most often left out of a brief and most often complained about afterwards.
4.Limits that come from the building rather than the flat
An apartment sits inside rules written by other people, and those rules shape a project earlier than any design decision does.
Ask the managing agent or building owner what they need to know before any internal work is considered, and record the answer in writing.
Buildings differ enormously in what they ask for, and the answer changes what is worth designing at all.
What a building requires before work begins is for the building owner, manager and the relevant authority to confirm, not for a checklist to state.
Gather your ownership or tenancy documents and note the sections that mention alterations, floor coverings or noise, without interpreting them yourself.
Bringing the relevant pages to a qualified adviser is far more useful than bringing a summary you have written from memory.
Interpreting a lease or ownership document is a matter for a suitably qualified professional advising on your situation.
Work out which walls, floors and ceilings you share with neighbours, and which rooms in your flat sit against which of theirs.
Shared surfaces shape where noisy activities and machinery can sensibly be planned.
Ask what the building requires in relation to floor coverings and sound transmission, and confirm it locally rather than relying on what neighbours have done.
Flooring is the change most often made without asking and most often disputed afterwards.
Requirements for floor coverings and sound in a flat must be confirmed with the building manager and the relevant local authority.
Record what the building permits in corridors, landings and any communal store, and note whether anything you own currently lives there informally.
Informal communal storage tends to be tolerated until it is not, and a plan should not quietly depend on it.
Note anything you have wondered about changing on the outside of the flat, including windows or ventilation outlets, and treat each as a question to confirm locally.
External changes to a flat usually involve more parties than an owner expects, so they belong on the question list early.
Whether any external alteration is possible at this address must be confirmed with the relevant authority and the building owner.
5.Storage that borrows height instead of floor
In a compact flat the floor is spoken for, so the useful questions are about what sits above head height and how deep a wall can become.
Look at the band of wall above door heads in each room and whether anything uses it, since this is often the last unclaimed surface in a flat.
High storage rarely feels intrusive because it sits outside the field of view people actually live in.
List the things you own that are needed rarely enough to live high up, and note what you would stand on to reach them.
High storage only works if the retrieval method is decided at the same time, otherwise it becomes a place things never come back from.
Ask a qualified professional what each wall in the flat can carry before planning anything heavy to hang on it, and record what you are told.
Wall construction varies widely in apartments, and the answer changes what kind of storage is worth drawing.
What any wall can support is for a qualified professional to assess, and fixings are for the relevant trade to specify and install.
Walk each room and note, in rough terms, how much depth a wall could give up before the route past it stops working.
Owners usually discover this by living around a taped outline rather than by looking at a plan.
Write down the objects that defeat ordinary shelving, such as long tools, sports equipment or anything that has to hang.
A single long or hanging item can decide whether a cupboard needs a tall compartment or a different location altogether.
Note whether the space under the bed and above the wardrobes is genuinely reachable, or whether it has become a place for forgotten things.
Reachability, not volume, is what makes concealed storage in a small flat useful.
6.How the flat handles moisture, stale air and sound
Compact flats concentrate cooking, washing and drying into very little air, and the effects show up on surfaces before anyone names the cause.
Note where condensation appears on windows, reveals or walls in colder weather, and record which room and which surface rather than guessing at a cause.
A record of where and when is what a qualified professional needs, and it is something only the occupant can gather.
Only a qualified professional who can inspect the flat should say what is causing condensation, damp or mould in it.
Record how each room is ventilated at present, including trickle vents, extract fans and windows, and note which of them are actually used.
Ventilation that exists but is never used behaves in practice like ventilation that is absent.
Record where laundry is dried and how long it stays out, since in most flats this happens in a living space rather than a utility area.
Drying indoors adds moisture to the same air the flat is trying to keep comfortable, so it belongs in the brief.
Write down which noises come from outside the building, which come from within it, and at what times each is noticeable.
The source matters more than the loudness, because internal and external noise are addressed by completely different people.
Record which rooms become uncomfortably warm, at what time of day, and whether opening a window is a realistic remedy there.
Overheating shapes where a desk or a bed can sensibly go, and it is easy to forget in colder conditions.
Ask a qualified professional what ventilation any enclosed or subdivided part of the flat would need before deciding to close a space in.
Dividing a compact flat changes how air moves through it, which is not something to work out after the joinery is fitted.
Ventilation for a subdivided or enclosed part of a flat is for a qualified professional to advise on and for the relevant local authority to confirm.
7.Getting anything large into a flat above the entrance
In an apartment the access route belongs partly to other people, and it decides what can be bought long before taste does.
Ask the building manager what the lift can take, whether it can be used for deliveries and whether it has to be booked or protected first.
Lift rules differ by building and are almost never discovered until a delivery is already at the door.
Count the flights and half landings between the building entrance and your door, and note any landing too tight to swing a long item around.
Communal stairs turn far more often than internal ones, and it is the turns rather than the doorways that defeat long items.
Ask what has to be protected in communal areas during a delivery and who is expected to arrange it, then record the answer.
Damage in shared areas quickly becomes a matter for the whole building, so responsibility is worth agreeing in advance.
Responsibility for protecting or repairing communal areas is for the building owner or manager to set out.
Find the narrowest doorway inside the flat itself, since the journey does not end at the front door and internal openings are often tighter.
Owners measure the entrance and forget the bedroom door, which is where the piece actually has to go.
Record how waste and old furniture would leave the building, including where a skip or collection could stand and who arranges it.
Removal is the half of the journey nobody plans, and in flats it is usually harder than the delivery.
Waste removal arrangements at this address should be confirmed with the building manager and the relevant local authority.
Ask whether deliveries reach your own door or stop at the building entrance, and note who would move an item the rest of the way.
In many buildings the last part of the journey belongs to the resident, which changes what can sensibly be ordered.
Preparation
Documents and information to gather
Having these to hand usually makes the first conversation shorter and more useful.
- A rough sketch of each room with bulkheads, boxing and service positions marked on it
- Photographs taken from the doorway of every room, and one looking back towards the entrance
- Your ownership or tenancy documents, particularly any pages that mention alterations
- Any correspondence from the building manager about works, deliveries or communal areas
- Notes on the journey from the building entrance to your door, including the lift and every landing
- Rough sizes of any furniture that is coming with you or staying where it is
Records
Decisions to record before work begins
Write these down in your own words, with the date, so everyone is working from the same version.
- Which parts of the flat are being accepted as immovable while the layout is developed
- The single use each shared room is being planned to protect above the others
- Whether storage will be built in or kept freestanding in each room
- What you are prepared to remove from the flat before anything new arrives
- Which questions must be answered by the building manager before design continues
Professional review
Questions to discuss with qualified professionals
Bring these to the relevant qualified professional, supplier or authority. Requirements vary by project and location.
- Which of the walls and enclosures in this flat would you treat as fixed until proven otherwise?
- What would you want to know about this building before drawing anything for it?
- What does the drainage position in this flat rule out that owners usually hope for?
- How would you approach ventilation if part of this space were enclosed?
- What would you want me to confirm with the building manager before we go further?
- How do you usually deal with storage in a flat where no wall is spare?
- What do owners of small apartments most often regret once the work is finished?
- What would you need measured properly rather than roughly before anything is made?
Blind spots
Commonly overlooked items
- The cupboard already occupied by meters, isolators or a heat interface unit
- The arc swept by an entrance door that cannot simply be rehung
- Where laundry is dried, and what that does to the air in a compact flat
- Rules about floor coverings and sound that belong to the building rather than the flat
- The lift, and whether it may be used for deliveries at all
- How old furniture and packaging leave the building once new pieces arrive
What this checklist does not do
- Nothing in a flat should be assumed removable, including boxing and bulkheads, until a qualified professional has established what sits inside it.
- Rules set by a building owner or manager apply in addition to anything confirmed locally with the relevant authority, and both have to be checked.
- Condensation, damp and sound transfer in apartments have several possible causes, and only a qualified professional who can inspect the property should identify them.
- This checklist prepares questions about a small apartment and does not decide what may be altered, enclosed or fixed to any part of the building.
