I discovered LOK Designs Company and decided to try them out. I was thrilled with their work on our new deck, which led me to hire them again for a family room and kitchen remodel including exquisite trim work and custom woodwork. They are exceptional — highly skilled professionals with golden hearts. They’ve become our go-to general contractor for everything we need.

FAQs Answers to Common Remodeling Questions
How long does a home addition take?
Every project is different, but most home additions take anywhere from several months to over a year depending on the size, complexity, permitting, and level of customization involved. We guide you through a clearly structured process from planning and design through construction so expectations stay clear from day one.
Do you help with design and planning?
Yes. We work closely with homeowners throughout the planning and design phase to help shape the layout, functionality, aesthetics, and overall vision of the project. Our process is collaborative and focused on creating spaces that feel intentional, cohesive, and built around how you actually live.
What makes a high performance build different?
A high performance build focuses on more than appearance alone. It’s designed for long term comfort, durability, energy efficiency, structural integrity, and healthier indoor living. This often includes better insulation, air sealing, moisture management, thoughtful mechanical systems, and construction methods that help the home perform better year after year.
Do you work on older homes?
Absolutely. Many of our projects involve working with existing homes, including older and architecturally unique properties. We take special care to ensure additions and renovations feel seamlessly integrated while addressing structural considerations, modern performance standards, and long term durability.
Will I need permits for my project?
Most additions and major remodeling projects require permits. We help guide homeowners through the permitting process and coordinate with the necessary professionals and municipalities to help keep the project moving smoothly and compliantly.
Can we live in the home during construction?
In many cases, yes, but it depends on the scope of work and which areas of the home are affected. Some projects can be phased to minimize disruption, while larger renovations may make temporary relocation more comfortable and practical. We’ll walk through those considerations with you before construction begins.
How early should we start planning?
Earlier than most people think. High quality additions and remodels require thoughtful planning, design development, budgeting, engineering, and permitting before construction even begins. Reaching out early helps create a smoother process and allows more time to properly design the space around your goals.
