Your family changes. Your needs change. Your home should be able to change with them. Whether you need an extra bedroom, a larger garage, a master suite retreat, or a sunroom that actually gets used — a well built addition does not just add square footage. It adds the space your life has been missing.
At Lucas Builders we approach every addition the way we approach every custom build. With in house design, fixed price contracts, and the same team from the first conversation to the final walkthrough. We handle everything including permitting so you never have to chase down paperwork or wonder if something was done to code..

01
Garage Additions
Need more room for vehicles, storage, or a workshop? We design and build garage additions that complement the existing architecture of your home rather than looking like an afterthought. Every garage addition is designed to feel like it was always part of the original plan.
02
Master Suite Additions
The bedroom and bathroom you have always wanted without having to move. We build master suite additions that feel like they were always part of the original floor plan. Designed around how you want to live, finished to the standard you expect.
03
Second Story Additions
When you are out of lot space but not out of options. A second story addition doubles your living area without touching your yard. Complex structural work that requires the right team. We evaluate your existing foundation and structure before we draw a single line.
04
Sunrooms and Three Season Rooms
Bring the outside in. We build sunrooms and three season rooms that extend your living space and work with the Minnesota climate rather than against it. A well designed sunroom becomes the room everyone wants to be in.
05
Mudrooms
A practical addition that changes how your whole home functions. Especially valuable in Minnesota where every season demands it. Built in storage, durable finishes, and a layout designed around how your family actually comes and goes.
In-House Design: You work directly with our design team from the very first meeting. No third party handoffs, no communication gaps. Just one team that knows your project from the inside out, from start to finish.
Transparent Pricing: We used fixed price contracts so you know exactly what you are paying before we ever break ground. What we quote is what you pay. Simple.
Local Knowledge: Growing up just up 694 in the Northeast Metro for years, we've become very familiar with Lake Elmo and the surrounding communities. The lots, the permitting process, the neighborhoods. Our local experience saves you time and eliminates headaches at every stage of your build.
How It Works
01
Consult
We start by understanding what you need and what your home can support. We evaluate your existing structure, your lot, and your goals before we draw a single line.
02
Design
Our in house design team develops plans that integrate seamlessly with your existing home. The goal is an addition that looks and feels like it was always there.
03
Build
We handle permits, manage the build, and keep you informed throughout. Work does not stop until every detail is right.
Addition costs in the east metro vary widely based on size, type, and finish level. A straightforward garage addition runs differently than a full second story. We provide detailed fixed price bids before any work begins so you know exactly what you are committing to. Schedule a free consultation and we will walk you through realistic numbers for your specific project.
Yes. Any structural addition to your home requires permits in Lake Elmo and across the east metro. The good news is, we handle all permitting on every project. You will never have to navigate the city or county permitting process on your own. I know, thank goodness!
This is one of the most common questions we're asked, and this is where our custom building background makes a difference. We design additions to integrate with your existing architecture rather than sitting beside it awkwardly. From rooflines to exterior materials to interior finishes, everything is designed to feel cohesive.
Not always. It depends on your existing foundation and structural system. We evaluate your home's structure before recommending a second story addition and we will tell you honestly if it is not feasible or cost effective for your situation.
Yes. We build year round. Minnesota winters slow some exterior work but they do not stop a well managed project. We account for seasonal conditions in your schedule from day one.
Most additions take between 8 and 16 weeks depending on size and complexity. We give you a detailed schedule before work begins and communicate with you throughout so you always know where things stand. Each project is different, and you can learn more about a potential timeline for you vision by scheduling your free consultation.
