Mascord Custom Home Design Services

Our Design Process

We take care of all you needs and desires throughout the process. Your design consultant will work with you to establish your criteria, budget and technical requirements.

Initial Consultations

The important part of initial meetings is that we listen to all your goals and dreams for your home, as well as your limitations. Then, as the design materializes, we can tweak things to suit your needs further, until it fits your lifestyle, property, and budget perfectly.


Design Completion and Review

When all the design elements are in place, preliminary design documents will be printed and evaluated with you, to make sure everyhing is complete. This final design will then be signed off as approved by you, and your construction drawings will be produced.


Construction Documents

With a custom designed home, we work with key collaborators in your project, such as your preferred truss manufacturer, site and stuctural engineers (or those we recommend) and other industry professionals to create a complete set of house plans ready for permit submittal.

Frequently Asked Questions

How do Mascord differ from being an "Architect"?

Our talented professional building designers create stunning unique home designs with neccessary code-compliant details to obtain permits and construct your home. We create detailed structural & permit documents that a general contractor follows to build your custom home.

However, where an Architect would source and list everything for your custom home (down to the nails and wall color) - we leave the sourcing and finite specification of and finishes to you and your builder. That helps you to maintain flexibility with choices, and greatly reduces the costs of creating the design.

With over 30 years' of award winning design experience, there are more than 65,000 families enjoying their Mascord homes. Join them, and get in touch with us today!

How much does a custom home plan cost?

Where a full service architect could typically charge a percentage of the total cost of construction, our custom services are instead a low cost based on the heated space (square footage) of the design. The price range will depend on the complexity of the house and the site, and the final price will be determined by the design specifications. Because the costs of our services are not based on the value of the home being designed - you can expect to save thousands over the usual costs of hiring a full-service Architect.

Additionally, we have a huge stock of existing plans that can serve as a starting point for your home's design - using one of those, you could potentially just pay to have the plan modified to suit your needs - saving more costs.

Do the plans include everything I need to get a building permit?

Our home plans are detailed to meet IRC (International Residential Code) requirements, and also Oregon and Washington local code amendments. Some areas require additional information, such as wind and seismic calculations, or energy code compliance worksheets. If you need any of these special items, we can work with professionals we have relationships with to provide them cost effectively, or you are welcome to use your own.

In addition, our construction support staff can assist you with questions or concerns from your building department - making the permiting process run smoothly. Some issues, unique to your situation, may incur additional costs.
