SIMPLE ADDITION,
– Basic Living Space –
You need more living space, but it doesn’t need to be fancy. This could include an extra bedroom or living room. No bathrooms or plumbing work.
- Basic Rectangle Shape
- Single-Story Design
- Simple Tie-In to Main Structure
STANDARD ADDITION
– Functional Living Space –
Your ideal addition is more than four walls and a roof. You might want an extra bathroom, or even build a second story on top of your current home.
- Kitchen or Bathroom Features
- Second-Story or Steep Lots
- More Complex Structural Design
COMPLEX ADDITION
– Custom Living Space –
The addition you need may present several design challenges. It’s structurally complex and includes a lot of custom construction.
- Extensive Custom Featues
- Multi-Level & Historic Home
- Structurally Challenging Design

As the lowest cost option, a simple addition will also have the most limited scope. An addition in this category would involve adding only living space to the home, such as a bedroom, office, or family room. Essentially, it’s an addition with four walls and a roof that is easy to design and construct.
Simple additions can be thought of as “best-case scenario” projects with no major challenges or issues. The land lot must be level and require minimal excavation. To avoid excessive engineering and design costs, the shape of the addition must be rectangular and follow standard structural principles.
A single-level bedroom addition built on the side of the home with a crawl space foundation is a good example of this type of project.
- Single level on the ground floor
- Slab or crawl space foundation
- Bedroom, living room, or office
- No major excavation
- Minimal plumbing & electrical
- Basic structural design

In the case that your addition requires extensive engineering or specialized construction throughout the design, that would qualify as a complex addition. This category of additions is reserved for projects that are exceptionally complicated in scope and design features.
An addition may fall into this category for several reasons. It may be because the planned addition drastically changes the structure of the existing home. Or maybe it’s because the addition is exceptionally large or complicated, requiring new plumbing, electrical, and HVAC systems throughout. It may also be that the project falls into a niche architectural or interior design style that involves specialized construction work to complete.
Additions on historic homes, multi-level additions, and additions that function as accessory dwelling units (ADUs) may fit into this category.
- 2nd story, basement, or multi-level
- Complex, custom shape
- Multiple rooms & functions
- New flooring
- Updated backsplash
- New lighting fixtures
- Custom features
