From foundation to finish, we supply the lumber, tools, and know-how that South Dakota builders have relied on for generations. Stop by and see what we've got.
Lakeside Lumber Inc. has been a fixture on G Avenue for decades — not just a place to buy two-by-fours, but a place where builders, homeowners, and tradespeople come for honest advice and quality materials.
When you walk through our doors, you'll find a team that knows the difference between construction-grade and select-grade, that can tell you which wood is best for a deck in our climate, and that will never sell you more than you need.
We're not a big-box store. We're your neighbors. And we take pride in helping you build right the first time.
From framing lumber to finished trim, we stock the materials serious builders trust — and we keep them in stock so you're never waiting around.
Pine, spruce, and engineered options for residential and commercial framing. Available in all standard lengths and grades.

We've been buying our framing lumber from Lakeside for over ten years. Their cuts are accurate, their prices are fair, and the folks here actually know what they're talking about.
I'm a weekend DIYer and I always feel a little out of my depth at big stores. At Lakeside, someone actually takes the time to help me figure out what I need — and what I don't.
When I needed a special order of trim for a restoration project, they got it in a few days. That kind of service is hard to find these days. Highly recommend.
Whether it's a new build, a remodel, or a simple repair — stop by 503 G Avenue or give us a call. We'd be glad to help you get the right materials for the job.
Thanks for reaching out. We'll get back to you as soon as we can — usually within one business day.
