Watch 100 Day Bach

Although Hamish and Anita overshoot their 100-day goal, they're thrilled with their finished bach and prepare to reveal it to family and friends.

Some creativity and an order for extra cladding gets things on track until moisture seeps in through the unclad side of the house and ruins the paint.

While the team installs windows, Hamish takes delivery of his kiln-dried lumber, but the builder runs out of cladding due to Hamish's miscalculation.

With their roof arrived and installed, Hamish and Anita can see their dream home becoming a reality -- until a startling discovery halts construction.

With a flat pack that can't get wet but dire weather on the way, the team races against time while facing another obstacle: incorrect fireplace specs.

The flat pack of the house arrives and takes overall shape within a day, but choosing bathroom fittings forces Hamish and Anita to face cost issues.

After some weather delays, the bach's foundation is laid, which forces Hamish to confront the reality of a smaller home than he had planned.

With winter approaching, Hamish and Anita must consider downsizing their original design, which they also realize may be facing the wrong direction.
