Frequently Asked Questions

How does the custom design process work at Spokane House Plans?

Our process begins with a consultation to understand your needs. We then sketch initial designs, refine them based on your feedback, and finalize the blueprints, ensuring compliance with local building laws. Once the plans are finalized, we'll then send you a PDF copy along with 2 copies of blueprints.

How long does it take to design a home?

The timeline depends on the project's complexity and revisions required. Generally, initial designs take 2 weeks, with additional time for changes and finalization. Expect the entire process from design to ready-to-build plans to take about 4-6 weeks.

What is the average cost of your design services?

Costs vary by project size and complexity, with custom designs starting from $1.60 per sq ft. Schedule a consultation for a detailed estimate.

Do you offer any guarantees on your plans?

We guarantee that all plans are compliant with local building codes when delivered and provide support throughout the construction process to address any issues arising due to our designs.

Do you incorporate green building practices?

Absolutely! We prioritize sustainable design and can incorporate elements such as energy-efficient materials solar energy solutions and water conservation features based on client interests and budget

Can you Mirror/Reverse the plan?

Yes! We can reverse (mirror) the construction set if needed. For example: you like the plan which shows garage on left side, but you need it to be on the right. We charge a small fee for this, please see our pricing.

How do Spokane House Plans address high wind and seismic design criteria?

Our stock plans require additional structural information and detailing in order to meet high wind and seismic requirements, which vary by geographic location and legal jurisdiction. For an additional fee, we can provide engineering to meet specific seismic zone, wind speed and wind exposure values for a specific building site. Such engineering analysis is site-specific and requires additional time to prepare. The drawings detailing this, and the supporting calculations, stamped by a licensed engineer are typically available for Washington or Idaho within a few days — check with our staff for availability in other states.

What design load values are used in the gravity calculations you provide?

The structure has been evaluated with Roof Live Load of 30psf, Floor Live Load of 40psf,  and Soil Bearing Pressure of 1,500psf. Otherwise, design loads follow the current I.R.C. code book. Calculations using different design values require additional time and fee. It is best to enlist the services of a local professional for such “location–specific” structural redesign. Local lumber yards sometimes have contacts for such services.

Can you modify/reverse the plan I liked?

Absolutely! If you find the plan you like but want to change it, we can easily do it for you. There is an hourly charge for revisions, or modifications. We can sit down and have you show us your ideas for modifications and we give you an estimate for time to complete the work. To reverse or mirror the plan we have a small fee, please see our prices.
