About us
Lot Line Builders is seven of us. Ivy Winfield runs the firm and still frames and trims on site. We build garage conversions, carriage houses and backyard cottages on Denver lots, and nothing bigger.
We started with the lot check because it's the part owners can't see: the rules decide most of what can be built, and we would rather tell you early than after drawings.

Who you'll meet
Four of the seven. The rest of the crew works under them.

How we work
If the lot can't take the building, you hear it in writing, with the rule that decided it, before you pay for drawings.
The utility route is on a drawing before it's in the yard, and you see it before we dig.
Your site lead answers your calls and texts, and he knows the whole job.
Start with a lot check, then we'll walk it with you.
