We own a Lindal cottage, known as a Prow Star, designed by Lindal Cedar Homes in Seattle, WA. Our Lindal home suffered major structural damages including a collapsed balcony, leaks and water intrusion damage into the building envelope, which we believe resulted from defects in Lindals design. Lindal has refused to take responsibility for the problem and has refused to rectify the damage. Last week we posted our concerns on Lindals Facebook page to see if anyone else has had similar problems and to warn other owners to look for these issues before they build. Lindal deleted our post asking for help and blocked us so we cannot post any further information. We have been paying very high annual maintenance costs since the structure was built in 1993. Despite all these efforts we are in a losing battle to save the structure as it's currently built. Here is a view of our cottage and the balcony before it collapsed: https://imgur.com/T3alfy6 Our collapsed balcony: https://imgur.com/SMVhPiA See this video of an authorized Lindal contractor inspecting our property and being informed of our situations: We discussed the design flaws here: https://youtu.be/EIJsa9V7WAA?t=210 We discussed the losing battle caused by the design flaws here: https://youtu.be/a-H2-xIbnt8?t=550 It was expertly built but unfortunately followed the Lindal plans which we now believe contained defective design elements. Some of the design elements that we believe are responsible for damage include: - The porch ledger board is attached directly to the 2 x 8 T &;;;;;; G siding. Water flows between the ledger board and the siding then becomes trapped. It then travels through the T&amp;amp;amp;amp;amp;G joint spilling down behind the wall between the back of the siding and Tyvek. Once there, it works through the seams where the Tyvek panels are taped together then into the plywood sheathing, framing, etc. See the design here: https://imgur.com/VMkOReK You can see the design flaw here: https://youtu.be/2mfmRSCczkA - The Roof-line design which directed a water pour-off directly against the side of a major structural glulam beam.

Also, the lack of window flanges around the perimeter of the Lindal supplied windows. Lindal wood windows from the 1990s are attached directly (via brickmould) to the siding of the cottage. The result, demonstrated below, is that once the water begins flowing between the back of the siding and Tyvek it travels on the Tyvek as it (the Tyvek) wraps under the top jamb of the window framing. The water then drops from the Tyvek and it rains from the top of the window jamb onto the sill below inside the cottage. See the design here: https://imgur.com/MCE3Ltw It pains us to leave this review but we feel that it is Lindals responsibility to address these problems. This is a family cottage and repairing the damage to our cottage will be a great financial burden to our family.
