What an Architect Typically Provides

Architects specialize in detailed planning for complex projects. This can include structural layouts, advanced design concepts, and technical drawings that prepare a project for review by building departments. Homeowners often hire an architect when they are making significant structural changes such as adding a second story or expanding a roofline. An architect can be especially helpful for homes in Minneapolis or St. Paul where older construction or historic elements may require more formal planning.

When You May Not Need an Architect

Many home additions do not require a separate architect. A design build remodeling company can often provide all the drawings, planning, and construction support needed for additions that do not involve complex structural changes. A design build team can create layouts, prepare construction documents, handle permitting requirements, and guide material selection. This approach can simplify the process and help homeowners stay within their preferred investment range, especially if you’ve already skimmed our remodeling cost guide to get a feel for what projects like this usually run. It is also common for design build teams to create plans that meet city requirements without needing architectural stamps.

How Willet Approaches Design for Home Additions

Willet Remodeling and Construction provides flexible options depending on the needs of your project. Some homeowners come to us with architectural plans that are ready for construction. Others prefer to collaborate with our drafting partner to create drawings that align with their goals. We also support homeowners who simply need detailed construction plans to meet local permitting requirements. Our process allows each homeowner to select the level of design support that fits both the project and the budget. It also helps ensure that the planning process stays efficient and focused.

How to Determine the Level of Planning You Need

Before deciding whether to hire an architect, consider questions such as:

• Are you planning a large addition that will significantly change the structure of your home? 
• Are you adding a second story or modifying major load bearing walls? 
• Does your city require stamped architectural drawings for certain project sizes? 

A contractor familiar with Twin Cities building practices will help you understand your options. Clear guidance early in the process prevents unnecessary spending and supports smooth communication with your city’s permitting office.

How Local Regulations Affect Your Decision

Local building departments across the Twin Cities have different requirements for home additions, which can influence whether architectural plans are needed. Some cities require detailed drawings for additions that modify structural elements, while others focus more on zoning limits, property setbacks, or foundation changes. Regulations may also apply when an addition involves installing new roofing to connect the expanded space with the existing structure.

Homeowners may need to update windows or doors to meet local energy standards, especially when creating new exterior walls that must align with Minnesota building codes. A contractor who understands these regional differences can help you navigate each requirement and determine the level of planning your project needs.

Frequently Asked Questions

Here’s what Twin Cities homeowners often want to know about additions and when architectural drawings come into play. The questions below offer quick, clear guidance to help you understand what to expect before planning begins.

Do all home additions require architectural drawings?

Not always. Some cities require architectural drawings only for large or complex additions, and many smaller projects can be approved with detailed construction plans created by a design build team. The size of the addition, the structural changes involved, and the city in which you live all play a role. Contractors familiar with local requirements can guide you toward the right level of documentation early in the planning process. This helps prevent delays and keeps your project moving smoothly.

Is a design build company enough for most home additions?

For many Twin Cities homeowners, a design build team is fully capable of handling everything from initial layout ideas to construction and final walkthroughs. These teams combine planning and building into one streamlined process, which reduces miscommunication and helps manage costs more effectively. Many types of additions such as family rooms, porch additions, or single level expansions can be designed without hiring a separate architect. The design build team will let you know if architectural support is required for your specific project.

Will hiring an architect increase the cost of my project?

Architectural services can add to the overall cost, especially for complex additions that require advanced structural planning. These costs may be worthwhile for certain projects, but they are not necessary for every home addition. A design build contractor can help you understand whether architectural plans are required or whether their internal planning services are sufficient. Understanding this early can help you plan your budget with confidence.

Can I bring my own architect to my project?

Yes, homeowners are welcome to bring their own architect if they already have someone they prefer to work with. A good remodeling contractor can collaborate with your architect to translate your plans into a clear construction process. This approach works well for homeowners who begin planning before choosing a contractor. Coordination between the architect and the remodeling team ensures your vision is executed correctly.

Who decides if architectural plans are required?

Your city’s building department makes the final determination based on the size and scope of your addition. Requirements vary by municipality, and it is common for different Twin Cities cities to have different expectations. Your contractor will help you understand what is needed for your specific location and project type. Early guidance helps prevent surprises and ensures your plans meet local standards.
