BACK CONSTRUCTIOn
What is a design agreement?
If you’re considering a major home remodeling project, you may hear the term design agreement during the early stages of the process.
For homeowners, this can raise an important question:
What exactly is a design agreement, and why do I need one?
A design agreement is an important step in planning a remodeling project. It establishes the scope of the design work, what the remodeling team will provide, what the homeowner can expect, and how the project will move forward before detailed design and construction begin.
For a significant renovation, this planning stage can help turn a general idea into a more clearly defined project.
What Is a Design Agreement?
A design agreement is an agreement between the homeowner and remodeling company that outlines the services and expectations for the design and planning phase of a remodeling project.
The exact contents can vary depending on the company and the project, but it may address things such as:
- The design services being provided
- The scope of the design work
- Project goals
- Deliverables
- Design fees
- Responsibilities of the homeowner and design team
- How revisions are handled
- Project expectations
- The next steps toward construction
Think of it as establishing the framework for the design phase before the detailed work begins.
A design agreement is not necessarily the same thing as a construction contract. The design phase comes first so that the project can be better understood and developed before construction is finalized.
Why Is a Design Agreement Important?
A major remodeling project involves many decisions.
Before construction begins, you need to determine what you’re building, how it should function, what it should look like, what materials will be used, what the project may involve, and how those decisions relate to your investment.
A design agreement helps establish a clear process for working through those decisions.
Instead of immediately jumping into construction, you have an opportunity to develop the project more thoroughly.
This can be especially important for:
- Kitchen remodels
- Bathroom renovations
- Home additions
- Whole-home renovations
- Basement remodeling
- Aging-in-place projects
- Complex renovations of older homes
Is a Design Agreement the Same as a Construction Contract?
No.
This is an important distinction.
A design agreement generally covers the design and planning phase.
A construction agreement or contract addresses the actual construction work.
The design process helps establish what is going to be built before construction begins.
A simplified process may look like:
Initial Conversation → Discovery → Design Agreement → Design → Budget & Scope → Construction Agreement → Construction
The exact sequence varies depending on the remodeling company and project.
Why Not Just Get a Construction Estimate First?
It can be tempting to ask for a final construction price before spending time on design.
For simple projects, a contractor may be able to provide a relatively straightforward estimate.
Major remodeling projects are different.
If you don’t yet know exactly what you’re building, it’s difficult to determine exactly what it will cost.
Consider a kitchen remodel.
Before construction, you may still need to determine:
- How much of the existing layout will change
- Whether walls will be removed
- Where appliances will go
- Cabinet configuration
- Countertop materials
- Lighting
- Plumbing locations
- Flooring
- Electrical requirements
- Structural changes
- Finish materials
Each decision can affect the scope and cost.
The design phase allows these issues to be explored and clarified.
Does Signing a Design Agreement Mean I Have to Build?
Not necessarily.
The answer depends on the specific terms of the agreement, so homeowners should carefully review the document and ask questions before signing.
In a design-build process, however, the purpose of the design phase is to develop a project that can eventually move into construction.
The important thing is understanding exactly what your agreement says, including how the design phase relates to a future construction contract.
Why Design Comes Before Construction
Good remodeling doesn’t begin with demolition.
It begins with understanding.
Before construction starts, your team needs to know:
- What you’re trying to accomplish
- How the space should function
- What the existing home can support
- What needs to change
- What materials are appropriate
- What the project may require
- What your priorities are
- How the scope relates to your investment
The design phase gives everyone an opportunity to work through those questions.
That planning can help reduce uncertainty once construction begins.
