Allow room for the door swing
Leave enough space on the terrace or indoors for open doors. The opening direction affects furniture, planters, curtains and everyday routes.
Proportions that fit
Sidelights can add daylight beside the doors. Coordinate width, glazing divisions and colour with your existing facade.
Doors that work with the patio and furniture
Draw the swing of both doors, including handles and where they should be held open. Allow for an outdoor table, planters and the passage along the facade. Say whether you want a low threshold and have it coordinated with waterproofing and patio levels. When comparing sliding doors, consider the usable opening and operating space as well as the overall width.
Make one leaf practical for everyday use
One leaf usually gets more use than the other. Put it on the everyday route and check its clear width. Consider where an open door rests and whether a stay is needed. Coordinate handles, curtains and insect screens so normal use does not require moving several components.
