Architectural Planning & Engineering

The Start of the Planning Phase

A majority of our projects are broken down into 3 phases. The Pre-Design Phase, the Design Phase, and then finally, the Planning & Permitting Phase. For more information on the three phases, please visit the Our Process page. A majority of clients who are looking for a design project are not only interested in getting their home designed in 3D. Most wish to obtain a building permit and structural plans for their project. This is where the Architectural Planning & Engineering Phase comes in.

After you have approved your floor plans and 3D home designs, we will then convert your designs so that they can be prepared for preliminary plans. The preliminary plans are simply a more finalized version of your designs, only on large plot paper and 1/4″ per foot scale. The preliminary plans are made up of the first few architectural pages. The site plan, the demo floor plan (if it’s needed), the new floor plan, the electrical plan, elevation views, and often section views. These pages more focus on what the home is going to look like vs how it’s going to be built. These pages come later, once your approve the preliminary plans.

Once the prelims are approved by you, then we continue on to structural planning. This is the second part of the Planning Phase and usually takes around 3 weeks to complete. During this time, our planners, engineers, and designers will develop the floor framing, wall framing, roof framing, foundation, additional sections, structural specifications and detail pages, as well as the Title 24 energy calculations page. Once the structural plans are ready, we can submit your plans for a building permit, where the Planning Phase continues.

The design team provided many renderings and options for our master bed and bath addition. From start to finish the work and customer service was exceptional.

By way of definition, the renderings that we produce at ER Home Designs, Inc. are actually called, raytrace images. These are images that are generated from 3D models that are created in our software. These raytrace renderings are intended for visualization purposes and are only intended to assist homeowners in their home design decisions. Unless otherwise specified, renderings are not to scale. Please visit our Gallery Pages for examples of raytrace renderings.
