Boise’s Warm Springs Castle is on the market for $3.4 million

If you’re in the market for a new home, why not a castle?

A mathematician and scientist, Tim Barber built what’s come to be known as the “Boise Castle” in 2010. Its construction on Boise’s historic Warm Springs Avenue initially fomented comments and controversy, but now is part of the neighborhood’s fabric.

The castle is fashioned out of Table Rock sandstone to look like a 13th-century castle, complete with portcullis (gate), turrets, stone hearths and lintels, loads of wrought iron details, rooftop torches and suit of armor. Plus, it has all the amenities of an upscale contemporary home.

You’ll find a whole-house smart system, LED lighting, hot tub, wine cellar and Viking kitchen appliances.

The four bedroom home (plus a one-bedroom apartment) is listed with Group One Sotheby’s International for $3.4 million.

There always has been local interest in the property. It even has its own website: And it’s known beyond Boise. It was featured on HGTV’s “Extreme Homes” in 2014.

Why a castle?

“I like stone structures and big projects,” Barber told Statesman columnist Tim Woodward in 2010. “It struck me that there are a lot of stone structures in town, even one with crenelations. That gave me the idea.”
