CHOOSING A HOUSE PLAN

What's included in a house plan set?
Each digital plan set includes detailed drawings to guide your builder, including floor plans, exterior elevations, a roof ridge plan, sections, electrical plans, and a foundation layout plan. You’ll choose your preferred file format — PDF or CAD — during checkout.
How do I choose the right house plan for me?
The best place to start is by identifying your must-haves and the details you already know — like how many bedrooms you need, your ideal square footage, and the width and depth that will fit your site. From there, you can narrow your search by foundation type and architectural design.
- Two-story homes are a great fit for families who want both shared and private spaces.
- One-level plans work well for aging-in-place or multigenerational living, with all key areas — kitchen, bedrooms, laundry, and garage — on the main floor.
No matter your lifestyle, we make it easy to filter by layout, lot type, or features to find a home plan that works for you.
And remember: the right floor plan is more important than the exterior style — design elements like finishes or façade details can often be tailored during the build process with your local team.
Can I build this plan on a sloped lot?
Many of our plans are designed with sloped lots and scenic views in mind – especially those with walkout or daylight basement foundations. Filter by foundation type to find which plans work best for your site.
What else do I need before I can build?
Building requirements vary by location. Here's what you may need before you can break ground:
- Site Plan: Shows where the home will sit on your property
- Site-Specific Engineering: A licensed local professional will assess soil conditions, frost depth, slope, seismic risk, and more
- Local Code Compliance: Our plans meet the 2018 International Residential Code (IRC), but your municipality may have additional requirements
- Professional Stamp (if required): States like CA, NY, NJ, IL, and NV often require stamped drawings by a local architect or engineer
We recommend checking with your local building department for a full list of what’s required in your area.
Can I customize my house plan?
Absolutely! Many of our clients choose a plan they love, then work with a local designer, architect, or engineer to make the changes they need. This is often the most efficient and cost-effective path forward — local professionals are familiar with regional building codes, permitting processes, and site-specific requirements, which can vary greatly across the country.
- If you're making minor edits — like flipping the plan to create a Right-Reading Reverse version — we offer flat-rate pricing upon checkout and can turn that around quickly.
- For larger customizations, like adjusting square footage, adding a basement, adjusting the ceiling heights, or changing the architectural style, we offer modification services through our founding design studio, LGA Studios, based in Colorado. We’re happy to provide a quote or help you decide if your project would be better handled by your local professionals.
