Schematic Design: What Those Early Blueprints Really Mean

A client called me last spring — retired Army, just separated from Fort Huachuca, ready to build on a piece of land he'd bought out near Hereford. He had a vision in his head: three bedrooms, a wraparound porch, shop space for his woodworking. He sat down with an architect, and a few weeks later he called me back, a little confused.

"Frank, they sent me these drawings but they look like… rough sketches. Did I hire the wrong person?"

He didn't hire the wrong person. What he received was exactly what he was supposed to receive at that stage. They're called schematic design drawings — and understanding what they are (and what they aren't) can save you a lot of frustration.

What Schematic Design Actually Is

Schematic design, or SD, is the first formal phase of the architectural process. Think of it as the "big idea" phase. The architect is drawing out the basic concept — how the building sits on the lot, roughly how big each room is, where the main entry goes, how spaces flow into each other.

These drawings are intentionally simple. You'll see floor plan outlines, maybe a basic exterior elevation or two. What you won't see yet: exact dimensions, electrical layouts, plumbing runs, window specs, or material choices. None of that has been decided.

The point of SD is to make sure everyone agrees on the general vision before spending time and money on the details.

Why It Matters — Even If You're Just Buying

Most of my clients aren't building from scratch, but this comes up more than you'd think in Cochise County. We've got a lot of rural land, custom home projects, and buyers who are purchasing properties mid-construction or buying a lot with plans already drawn.

Here's where schematic design matters to you:

• If you're buying land with existing plans, SD drawings tell you where the project stands. Plans stuck at the SD phase are very early — major changes are still easy and relatively cheap to make.
• If you're buying a partially built home, knowing the project moved past SD into later phases (Design Development and then Construction Documents) tells you the design was locked in and the builder was working off detailed, engineered plans.
• If you're a seller with a buildable lot and you're marketing it with architectural plans, SD drawings are a starting point — not a finished product. Be honest about that with buyers.

A Concrete Example

Let's say you're looking at a vacant lot in the Foothills area outside Sierra Vista. The seller has "architect drawings" included in the listing. You get excited.

You look closer and realize they're schematic drawings — basic room layouts, a rough footprint, a front elevation sketch. That's not a bad thing, but it's not a finished set of plans. To actually build from those, you'd still need Design Development drawings and then full Construction Documents, which is where structural engineering, mechanical systems, and permit-ready details get added.

Expecting SD drawings to be construction-ready is one of the most common mistakes I see. It's like mistaking a rough draft for a published book.

The Bigger Mistake to Avoid

Don't skip this phase trying to save money. Some owners push architects to jump straight to detailed drawings before the concept is right. That's expensive. Changes made at the SD stage cost almost nothing compared to changes made after full Construction Documents are drawn — or worse, after construction starts.

If you're building in a rural area of Cochise County, where lot conditions, water access, and setback requirements can throw surprises at you, getting the SD right before moving forward is especially important.

Your Next Step

If you're looking at a property with plans attached — or if you're starting a build — ask one simple question: What phase are these drawings in?

Schematic Design, Design Development, or Construction Documents. Each answer tells you exactly how far along the project is and how much work (and money) is left to get to a permit.

Not sure how to read what you've got? Bring them to me. I've been around enough builds in this county that I can at least point you toward the right questions — and the right people to answer them.
