Double-duty furniture, ceiling-height curtains and one calm palette: three tricks that visually double a small flat.
Small flats feel bigger when every piece earns double duty. A drop-leaf table seats four and folds to a console; a storage ottoman holds bedding and seats guests; the bed lifts to swallow suitcases.
Borrow light and sightlines: hang one large mirror opposite the window, keep curtains at ceiling height, and choose leggy furniture so the floor reads continuous underneath.
Finally, edit color. One calm palette across rooms erases visual borders, and suddenly the whole flat reads as one generous space.
