Ask this before a small space design mistake becomes permanent: a short checklist

What to take away

Ask what the plan does to the way out before you ask what it looks like.
Ventilation and combustion appliances deserve their own question.
Ask which decisions are reversible and which are not.
A designer who asks about your household is worth more than one who does not.

Hiring a designer to fix a compact room is a good idea. Hiring one who only discusses appearance is how a second set of mistakes gets installed. These questions filter for the difference.

Questions about how people leave the room

Start here, because it is the question a weak designer skips.

Egress questions to ask

Two usable ways out of sleeping area
Nothing blocks an openable escape window
Doors keep swing and approach clearance
Smoke alarm clear of new millwork

Egress is a discipline, not an instinct. The Access Board's guide to accessible means of egress, developed with the International Code Council, describes a means of egress as an unobstructed path out of a building or space: exit access, exit and exit discharge.

That guide also notes the International Building Code generally requires at least two means of egress from spaces and buildings, with limited exceptions where travel distance is short and occupant load is low.

The guide addresses buildings covered by the ADA rather than your apartment, and your requirements come from the residential code your jurisdiction has adopted. A designer who cannot discuss exit access in those terms is not thinking about the part that matters.

The failure is rarely the plan. Our five lessons from compact projects describe what actually closes a second way out, which is storage that grew a little at a time until it reached the window.

Questions about air and combustion

Where does the exhaust actually discharge, and is it ducted to outside?
Does anything in this plan block a supply register or a return?
Do we have any fuel burning appliance in or near this space?
Where do the carbon monoxide alarms go under this layout?

Settle the exhaust question before anything else in this section, because retrofitting a properly sized and ducted fan means opening the ceiling again. Our guide to what to do while the walls are open puts ventilation in the tier that cannot wait.

Air and combustion checks

Exhaust ducted to outside, correctly sized
Supply registers and returns unblocked
Identify any fuel burning appliance
Place carbon monoxide alarms per code

The National Fire Protection Association calls carbon monoxide the invisible killer. It is an odorless, colorless gas made when fuels burn incompletely.

In a compact home, a sleeping area may sit near a kitchen or utility closet. Alarm placement is a design decision. Confirm required locations with your building department.

Questions about the household

A good designer asks these before you do:

Who lives here, and who visits regularly?
Is anyone in the household sensitive to fragrance, dust or noise?
What does a normal weekday morning look like in this room?
What has already been tried and rejected?

Questions about reversibility and money

Which of these decisions can be undone, and at what cost?
Which need a permit, and who will confirm that with the building department?
What is your fee structure, and does it include revisions?
Do you specify products, and do you receive anything from suppliers?

Weak answer

Two ways out?: It looks fine
Where does exhaust go?: Up
Reversible?: Everything is fine
Supplier payments?: Avoids the question

Strong answer

Two ways out?: Names both and checks them
Where does exhaust go?: Ducted to outside, sized
Reversible?: Splits the list in two
Supplier payments?: Discloses plainly

The mistake list these questions are designed to prevent is in our guide to small space design mistakes, and the contractor version of this conversation is in our piece on renovation hiring questions.
