About BLD House

BLD House: An Integrated ADU Design-Build Approach

BLD House operates as a fully in-house design-build company, meaning they manage their own projects directly rather than outsourcing to third parties. This integrated structure gives them direct control over cost, quality, and schedule — a distinction they draw clearly when compared to other ADU contractors in the market.

As an accessory dwelling unit builder, BLD House works with a team that includes architects, structural engineers, and consultants, all operating under one roof. This setup allows them to guide clients through the entire process, from initial design to project completion, without the coordination gaps that can arise when multiple separate firms are involved.

BLD House has launched a modern prefab ADU line, with the first unit being a 1 bedroom / 1 bathroom, 500 square foot design, starting from $299,000. This is the first in a series of designs planned for release, reflecting their focus on expanding prefabricated ADU options for their clients.

A Modular Approach to ADU Construction

At the core of BLD House's strategy is a modular, off-site construction method. Rather than relying on traditional site-built techniques, they build their ADU units off-site. This approach is intended to streamline the construction process, reduce material waste, and create cost efficiencies that can be passed on to the client.

Building off-site also allows BLD House to maintain consistent quality standards throughout the construction process. Their detached ADU builder and granny flat builder services are designed with both functionality and aesthetics in mind, aiming to deliver units that are practical without sacrificing design quality.

Clients working with BLD House can expect choices across several design categories, including:

  1. Roof options
  2. Exterior finish options
  3. Interior palette options

These customization options allow for some degree of personalization while still operating within a streamlined, process-driven framework.

Design-Build Process and Client Experience

BLD House describes their client experience as simple and fully integrated. They work exclusively with their preferred in-house architects, keeping the design-build path straightforward and consistent. The goal is to make the process easy to understand and to avoid the complexity that can come with managing multiple contractors or consultants independently.

As a company, BLD House states a broader commitment to addressing issues of affordability, accessibility, and density in the markets they serve. Their prefab ADU line is positioned as one way to work toward those goals — offering a backyard cottage or in-law suite solution that is both cost-conscious and design-forward.

Their current offering represents the beginning of a broader product line, with additional ADU designs expected to follow as part of their ongoing development in the prefab space.

BLD House Reviews

"I recently had my home built in Shevlin West with Adair, and the experience was great - better than I expected. They were easy to work with from day one. The design process was straightforward I went to their office in Redmond to work through it, they let me tweak things as much as I needed up to the final design, and they offered the best mortgage rate around, which makes a huge difference in what the overall cost of a build will be. But despite being more affordable, they still delivered a high quality home. My lot is sloped, full of rock, and needed a ton of excavation. Even with all that, they still came in under budget thanks to some re-negotiating of the excavation by Lori and their recommendation to put the garage on the street level with the home on the second worked out relaly well - the view is incredible. One thing I really appreciated was how they keep you in the loop. Someone helps you through all the design choices, and then someone else updates you during the build. Both were super responsive and made the whole thing feel manageable. Even after the house was done, Chris was quick to help with little things most builders probably wouldnt bother with. The final cost actually came in under the original estimate I even got money back at the end, which was a very pleasant surprise. The timeline took a bit longer than I expected, but that was mostly Bend permitting and the usual construction variables. I never felt like I had to compromise on anything. Overall, Im really happy with how everything turned out. The team was great, the house is great, and Id definitely recommend Adair to anyone considering building."

"We had a great experience working with Adair homes. Lori was easy to work with and very responsive to all of our questions and requests. Lori and Chris helped make the process of building a home as easy as it could be. When any issue came up it was dealt with promptly. We would highly recommend Adair."

"We are in the pre-build phase of our Adair home in Sisters. The team has been helpful, flexible, and very professional. We are not located in Central Oregon, so having the team accommodate us virtually has been a huge plus saves us 5 hours of driving per meeting!. We are just about to enter the permit phase, and are excited for next steps. Lori Jeter has been especially great to work with! And we look forward to working with Gary Williams and Mike Nelson, as well!"

"My family and I have had a wonderful experience with Joe Zampko of Adair Homes. Sincere and professional communication from the start. Any questions or concerns were answered in a timely manner and any hiccups were fixed satisfactorily. Adair homes has really been the best decision I have ever made. My family and guests are impressed with the grandeur of my new home and the craftsmanship. We had security knowing we chose to have Joe represent us during this build and would recommend him to any one looking for an highly knowledgeable representative. We could not be more pleased with our overall experience."

"Adair has been incredible to work with on building my first house. This will not only be the first home Ive had built, but also the first home Ive owned. Everyone there has be extremely helpful at every step. Joe was great at explaining the financing, all the budgeting, and really helped when working with the lending agency. Victoria has been awesome at getting the timeline and project management worked out, as well as explaining my roles and responsibilities, and Shawn has been great at managing the actual build of the home. Working with adiar themselves has been a 1010 experience."
