September is one of my favorite times of year… not just as the start to cooler weather, leading to the best season of all, Fall; but also for the month-long LEGO building challenge known as SHIPtember. The goal is to build a spaceship that measures at least 100 studs in any dimension: length, width, or height. Or even diagonally (like a Borg cube). The only other constraint is that you must complete your ship within one month. The SHIP in SHIPtember stands for Seriously Huge Investment in Parts, and it shows in the final ships, which can stretch beyond the minimum into the 200-300 stud range. Having participated in SHIPtember for the last 10+ years, I can personally attest to both the challenge and the satisfaction in pushing yourself beyond your comfort zone as a LEGO builder, not to mention the incredibly supportive and collaborative community of SHIP builders around the world.

This year, the Brothers Brick will be taking a closer look at SHIPtember in the coming weeks, checking in with builders and sharing starships in progress before rounding up the SHIPs that launch for the stars at the end of the month.

Before we start our week one coverage, I should mention that some SHIPs are already done, as some builders, like college students, may not have full access to their collections during September, and start their SHIPs in August. As long as the builds stick to the 1-month requirement, they are every bit as eligible as those under construction now. I will also be sharing my own SHIPtember progress each week, at the end of each feature. With that out of the way, let’s jump into SHIPtember 2025 week 1!
