Transform Your Basement into a Livable, Beautiful Space
At Tortoise Construction LLC, we specialize in basement renovations in Portland and the surrounding areas that turn unused and outdated spaces into functional, beautiful rooms. Whether you want to create a home office, a cozy family room, a guest suite, or a rental-ready basement apartment, we design spaces that match your needs and style.
Our team handles every step from layout planning to final finishes, making sure your basement remodel is comfortable, safe, and built to last. We have completed basement renovations in Portland, Lake Oswego, West Linn, Tigard, and other nearby communities, each one customized to fit the homeowner’s vision. We can add modern lighting, energy-efficient insulation, waterproofing, and durable flooring to transform your lower level into a space you will love.
A finished basement offers more than extra square footage. It increases your home’s value and provides versatile space for work, entertainment, or family. Whether your basement needs a complete overhaul or just a thoughtful update, our goal is to deliver results that blend quality craftsmanship with functional design.
