Interior and landscape are separate scopes, priced and delivered separately. Neither one requires the other.
Plenty of homes take the inside first and add the grounds two seasons later; plenty do the reverse, because the landscape was already being torn up. When they do run together, most of it happens without anyone touching anything. An astronomic schedule follows sunset as it drifts an hour and a half across the year, so the path and facade come up on their own. Away drops the house to zero and holds the exterior until midnight. Welcome brings the drive, entry, and foyer up as the gate opens. Dinner Party reaches past the glass so the yard doesn't go black the moment the sun does. If you'd rather press something there's an engraved keypad at the wall, a phrase to a voice assistant, or the app — but nothing depends on it.
The same schedule drives color temperature, which is where lighting stops being decoration. Cooler, brighter light through the morning and a slow slide toward 2200K after dinner tracks the daylight the body evolved to read; the research on circadian lighting associates it with falling asleep faster, steadier energy through the afternoon, and better sleep overall. We set the curve at commissioning and it runs quietly for years — nothing to maintain, one number to call when a lamp finally goes out.
