[It's not hard to see the excuse for what it is, but Alhaitham knows better than to press on it. He's learned just enough tact with Kaveh, and its also clear that continuing the conversation would not benefit either of them any further. These things that Sherlock has chosen to reveal to him—the significance in them is profound, and Alhaitham will not take it lightly.
It's also why he only speaks up after Sherlock has gathered his items and stood up, and should Sherlock look over to him he will see that Alhaitham is looking directly at him, gaze as unwavering as always, as steady as the words that he speaks.]
Kaveh made this place as a way for the two of us to have something that feels like what we remember of Sumeru. [Of course, its nowhere close to the real thing, but it doesn't change the fact that Kaveh has done everything he can to emulate the environment of the forest that they know of. Things such as how the trees can absorb and block out noise, to hear the leaves that rustle and sway—and perhaps more importantly, a way to block out the sight of water and even insulate from the noise, should one desire it so.] Just something to consider, if you ever require a temporary change in your environment.
[That's about as transparent as Alhaitham will get with giving Sherlock free reign to come and go as he pleases here, should he ever need it. He doubts Kaveh would mind, seeing as how the architect hasn't said anything about Sherlock sleeping here.]
