NVR, Inc. operates in two business segments: homebuilding and mortgage banking. The homebuilding unit sells and constructs homes under the Ryan Homes, NVHomes, Fox Ridge Homes and Heartland Homes. As a corporate entity, NVR, Inc. provides various support functions for each of its sub-entities. These include sales and marketing support, vital human resource specialists, and an advanced information technology department, which provide a network of resources utilized by NVR, Inc. holdings.

"We absolutely love our new Ryan home, which is ready to move into. Jon, the construction manager was true to his word, and had the Home completed by the end of May. However., DO NOT GO WITH NVR MORTGAGE! We were supposed to close June 7, and Martha from NVR knew we wanted an early June close, I was retiring July 1st, and our mortgage was based on my pension MONTHS AGO. Now, a few weeks before closing after we scheduled a TON of services including movers, truck, friends taking off to help, babysitters for kids, and have a buffer of 3 weeks before we have to move out of a rental end of June; Martha tells me they require a certain letter from the pension that I will not receive until mid-july. Because of this they initially said we couldn't close until July. Then it is June 20th. If she provided us with this information months ago, we could have planned differently. Now we are scrambling to figure out what to do. So, I repeat, DO NO GO WITH NVR MORTGAGE. I'm not the only one either. I just spoke to our new neighbors who broke off with NVR and Martha after 6 months before closing because of similar issues. DO NOT GO WITH NVR MORTGAGE!!!! it should be NO STARS FOR NVR MORTGAGE."

FAQs for addition to existing structure building service projects in Westfield, IL

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.
