Custom House Plans
A custom house plan is drawn around one lot: yours. We draft site-specific working drawings that account for your property's actual dimensions, orientation, and constraints, coordinate directly with your structural engineer, and carry the design through a real revision process to a finished, permit-ready set.
What Custom House Plans Are and Who They're For
Custom house plans start with a blank sheet and your lot survey, not a catalog. Every wall, window, and room placement is drawn to respond to the property you actually own: its shape, its setbacks, its slope, its sun exposure, and the view or privacy considerations that matter to you. Nothing is force-fit from a generic template.
This service is the right fit if you own a lot with any irregularity or opportunity worth designing around, a narrow infill site, a sloped or view lot, a corner parcel with unusual setback rules, or if you simply have a specific program in mind that a pre-drawn layout will not deliver. It is also the right call if you are working with a builder or contractor who needs a fully coordinated, buildable set rather than a starting point that requires heavy rework.
If your priority is a lower entry cost and a proven layout you are comfortable adapting, our stock house plans starting at $799 may be a better starting point. Custom drafting is for homeowners, builders, and contractors who need the design built around the site and the goals from the first line drawn.
What's Included
- Site-specific floor plans developed from your lot survey and program
- Exterior elevations for all sides of the home
- Building sections and construction details needed for permitting and framing
- Structural coordination with your chosen engineer, so our drawings match their calculations and details cleanly
- A defined number of revision rounds, confirmed in writing at quote, to refine layout and design before finalization
- A full permit-ready working drawing set prepared for submittal to your local jurisdiction
Every custom project is scoped individually. If your project also calls for 3D visuals to review the design before it is finalized, or specific accessibility or aging-in-place features, those can be added; see 3D Renderings & Walkthroughs and Multigenerational & Universal Design below.
Our Process for Custom House Plans
1. Site & Program Intake
We start with your lot survey, any existing site conditions, and a detailed conversation about how you want the home to function: room count, square footage targets, and priorities.
2. Preliminary Layout
We draft an initial floor plan and massing built specifically to your lot's dimensions and orientation, giving you a real starting point to react to rather than a generic template.
3. Revisions & Refinement
You review the layout and elevations and request changes. A set number of revision rounds is included and confirmed at quote, giving you real room to get the design right.
4. Structural Coordination
We coordinate directly with your structural engineer so beam sizing, framing, and structural details are fully integrated into the drawing set, not bolted on afterward.
5. Working Drawings
We finalize full construction documents: elevations, sections, and details built to be buildable in the field, not just approved on paper.
6. Permit-Ready Delivery
You receive a complete drawing set prepared for submittal to your local permitting jurisdiction. See Permit-Ready Drawings & As-Builts for more on this step.
Turnaround
Because every custom house plan is drawn from scratch around a unique lot and program, timelines vary by project scope, design complexity, and the permitting jurisdiction the project is submitted to. We will give you a specific, honest timeline estimate once we understand your site and your goals at quote, and we will flag anything mid-project that could shift it.

Custom House Plans FAQ
How is a custom house plan different from a stock plan?
A custom house plan is drawn from scratch around your specific lot, orientation, setbacks, views, and how you actually want to live. A stock plan is a pre-drawn design you adapt to your site. If you want a layout built around your property and your list of priorities from day one, custom is the right starting point. If you want a proven layout at a lower entry cost, our stock plans start at $799 and can often be modified.
Do you provide structural engineering with custom house plans?
We handle the architectural drafting and coordinate directly with the structural engineer of your choice, whether that is your engineer or one we can point you toward. Structural calculations, stamps, and engineering fees are handled by the engineer of record, not by our drafting scope, and we build our drawings to match their input cleanly.
How many revisions are included in a custom house plan project?
A set number of revision rounds is included with every custom house plan project. The exact count is confirmed in writing at quote so there are no surprises, and it is scoped to give you real room to refine the layout before drawings are finalized.
How long does it take to get custom house plans drafted?
Timelines vary based on project scope, the complexity of the site, and the permitting jurisdiction you are building in. We give you a specific timeline estimate at quote once we understand your lot, your goals, and where the project is permitting.
Can you draft custom house plans for any state?
Yes. Apex Drafting is a fully remote drafting company and we serve clients nationwide, with a particular focus in Texas, Florida, New York, and California. We work from your lot survey, local code requirements, and your jurisdiction's submittal standards no matter where the project sits.
What do you need from me to start a custom house plan?
At minimum we need your lot survey or site information, your program (bedrooms, square footage, and how you want the home to function), and any inspiration or must-have features. If you already have an engineer selected, we will coordinate with them directly from the start.
