"Let me start by saying, this ADU project was for my daughter, Macy. Macy has I/DD and Autism and will likely not be able to live away from us, her parents, unless she is in assisted living of some sort. However, together with her grandma we sought to create an environment for her to live as independently as possible and for her to grow into. This began our search for the perfect contractor who would understand our needs and work with us to build this ADU for Macy. Enter, Jay Bemis with Timeless Builders. After multiple meetings with contractors, many unreturned calls and emails, we met Jay. He immediately sounded interested and returned with a bid in a timely matter. We accepted this bid and began to move forward with this project. As with any construction project, we ran into unexpected situations. I could not have picked a better partner to handle all of these situations. He maintained focus on finding solutions, worked magic to make things happen that we wanted and came up with additional creative ideas when we couldn’t. He is a true craftsman and he employs the most amazing people! The pandemic hit during our project and he was respectful of our request to wear masks when entering our home. They continued the work and Jay was open about end dates and timelines. If you are looking to start a project, I can tell you that Jay Bemis and his team at Timeless Builders is who you want to partner with. Their work exceeded our expectations, their friendliness was an added bonus and the end result blew us away. Don’t think twice, contact Jay with Timeless Builders, he will help you get your project done right."

FAQs for addition to existing structure building service projects in Welches, OR

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
