The two phrases do seem to me to be general (or generic or indefinite or habitual) conditionals but the verbs in both protases (οἰκοδομήσῃ and φυλάξῃ) are aorist (past) subjunctives not present subjunctives, and the verbs in the apodoses (ἐκοπίασαν and ἠγρύπνησεν) are also aorist tense not present tense, so I don't think you can call these conditionals *present* general. My understanding is that the emphasis here by using aorists is the aspect (perfective) not the tense (past). Aorist verbal stems have perfective aspect, which means they present the action as a complete whole; present verbal stems have imperfective aspect, which means they present the action as ongoing or repeated.
So the perfective aspect here says to me: "Unless the Lord has built the house, those building have labored in vain." i.e. the statement is presented as a general truth.
CGCG chapter 33 has a really good explanation of verbal aspect ;-)
