Surrounded by grandkids - but with a quiet spot all his own - this cottage has created the chic retreat of his dreams.

Sometimes, you need a retreat within your retreat - especially when the serene cottage you purchased for your young family more than 40 years ago is today teeming with energetic grandchildren (nine under the age of 10, to be exact).

Wanting to stay close to his family but also enjoy the serene lakeside living, the homeowner envisioned a brilliant solution: to build a cabin (which would be his and his alone) beside the original bungalow (which he’d let his children and grandchildren take over).

One Torontonian bought his original cottage on Lake Simcoe in the early ’70s, when his own three kids were less than 10 years old. There, the siblings filled those lazy, hazy days of summer with quintessential Canadian cottage experiences, such as learning to swim, spotting wildlife and roasting marshmallows. But now that the owner’s kids have their own kids, the laughs and crafts, games of tag and, yes, inevitable tears are sometimes too much.

So in 2010 he hired the Toronto-based architectural firm Superkül and designer Stacy Begg to create his kids-free bunkie: an 840-square-foot two-bedroom space that boasts its own private entry, kitchenette, bathroom and deck, and is connected to the cottage via a long glass-walled walkway. “The addition is contemporary, pure and minimalistic – yet warm,” says Andre D’Elia, the principal architect. And that’s precisely what the homeowner, an avid reader of modern architecture magazines like Dwell, wanted. “Plus, the quiet, restrained design allows the majesty of the setting to dominate,” says Andre.

“The contemporary pale wood finishes paired with white-painted walls make it a soothing home-away-from-home in which the owner can unwind and de-stress,” says Andre. But this doting grandfather is never completely removed. He eats almost every meal with the main cottage clan, which often swells to more than 15 people; and when he’s ready for even more action, he visits the adults sunning on the dock or invites his grandchildren over to watch a movie before bed. As much as the cottage is, for kids, about running barefoot, collecting caterpillars and spending all day swimming, for adults, it’s about something entirely different: listening to the leaves rustling in the wind and the waves lapping the shore, watching sunrises and sunsets, taking deep breaths of fresh air and simply slowing down. But it’s wonderful to have little ones around to remind you of what it used to be about.
