Quality, ingenuity, sustainability licensed and insured home remodeling specialist. We focus on providing our clients with the best construction experience. Give us a call today and we promise to take care of you!

"What a project! The initial plan to expand our lake house and add a level turned into a total rebuild due to discovery of standing water and rot. This project landed during the COVID pandemic and met with some unavoidable delays. Throughout the project my husband and I met with Matt and Steve regularly (weekly). Matt was always organized providing a list of items we needed to discuss, decisions that needed to be made and timelines for next steps. Matt and Steve consistently offered many ideas for ways to achieve what was important to us (kitchen layout with view to lake, beverage area, ample work surface, closed laundry area etc.), finish options (siding, roofing), lighting options etc. Though the project took longer than planned (thank you COVID), the result is a beautiful, comfortable home. We are very happy with the end result!"

FAQs for addition to existing structure building service projects in Ann Arbor, MI

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.
