Remodel & Addition Plans

Your home already has a story — our job is to help you expand it the right way.

At 1720 Designs, we create custom remodel and home addition plans tailored to your goals while respecting the existing structure, rooflines, and flow of your home.

Whether you're updating a kitchen, reworking a layout, or adding square footage, our design process focuses on functionality, comfort, and a seamless “it was always meant to be here” result.

Serving Cullman, Huntsville, and across North Alabama, we help homeowners transform spaces with plans that are clear, buildable, and designed for real life.

• Kitchen and bathroom remodels 
• Primary suite additions 
• Family room additions and open-concept conversions 
• Garage conversions and garage additions 
• Mudroom and laundry expansions 
• Bonus rooms, offices, and home gyms 
• Porch additions, covered patios, and outdoor living spaces 
• Whole-home renovations and layout reconfigurations 

Design that fits your home
We evaluate existing conditions and design around structure, circulation, and proportion so the addition feels integrated, not tacked on.

Plans that support confident decisions
We help you visualize the changes and refine the layout before construction begins, reducing surprises and rework.

A smoother path to building
Our drawings are prepared to support contractor pricing, permitting, and coordinated construction.

Remodels and additions require detailed coordination with existing structures. Pricing reflects the additional planning and technical review involved.
