"Bear Remodelling just finished our kitchen remodel and we couldn't be happier! Our 1980s kitchen was cramped and dark, but now it's open, bright and functional. The team guided us through picking cabinets, countertops, and backsplashes that worked together perfectly. What impressed me most was how clean they kept our home during the process - they put up plastic barriers and cleaned up daily. The project manager kept us updated with daily progress reports and was super responsive whenever we had questions. The new island they installed gives us the extra counter space we desperately needed. Worth every penny!"

Barndominium Builders questions, answered by experts

Whether it is better to buy or build a chicken coop depends on your priorities, primarily cost versus time and effort. Building your own chicken coop can be significantly more budget-friendly, often costing about half as much as buying a pre-made one. If you have the time and skills, building a coop from scratch is the most economical option. However, if your time or skills are limited, buying a kit and hiring a handyperson to assemble it can be more cost-effective than hiring a carpenter to build a custom coop from scratch. If you want a perfectly constructed coop without sacrificing your own time and energy, buying one is the easiest choice.

The lifespan of a barn is typically 40 to 60 years, but with skillful construction and proper maintenance, it can last up to 100 years. The actual lifespan depends on several factors, including the barn type, materials, usage, and climate. For example, the posts of a pole barn should last 50 years or longer, but if the structure is used for livestock in a rainy climate, it may rot within the first decade. Custom designs with high-end materials tend to last the longest. To get the best estimate for your barn's lifespan, you should consider its material type and intended use.

It’s much less expensive to build a house with wood. This is because wood is relatively inexpensive, strong enough to endure decades or even centuries of weathering and pressure, and is easier to replace if there are issues. The cost of stone houses are incredibly expensive, heavy, time-consuming to build, and difficult to repair. 

Yes, barndominiums are designed to withstand strong weather and severe storms if they are built properly by trained professionals. Most barndominiums are made up of a steel structure that can protect a building from winds of up to 150 miles per hour and resist a variety of weather conditions without a major risk of structural damage to the exterior, foundation, or frame.

A steel frame costs 10% to 20% more than a wood frame. Wood is a much easier material to work with, more accessible, and generally more affordable than steel—plus, you need specialized tools to work with steel.
