Browse Forums Building A New House 1 Jul 09, 2021 4:25 pm Hello all, We are finalising our custom home design, there is a silicone joint window which our architect suggests will be nice feature for the living room. It will be a fixed window to the adjacent courtyard. He is unsure about the additional cost or the structural requirement, however suggested it may not be complicated as it is a single storey home. Would someone please advise me, whether will it be a hard job and requires complicated steel beam frames? And any cracks will occur in the future? Approximate additional cost involved? Any advice will be appreciated. Thanks.

There are plenty of display houses with that feature over here. I think the main issue with them is that you can't do double glazing, if that's something you want. Re: Silicone joint window- structural requirement? 3Jul 09, 2021 8:37 pm Will need steel beams to pick up the bricks above - or, if the windows run floor to ceiling, maybe one steel, and one timber beam to support the roof. Distance between bottom window and the wall near the niche seems quite substantial. Not complicated, but would cost afew extra thou.

Hello Strannik, Really appreciate your help. We are considering double glazing, so that must be an issue.

My concern was, how they do brickwork above that window? One of the builders suggested it needs some cantilevered metal beams to support the structure and the brickwork. Another builder said there is no brickwork coming on top of the window, so it doesn’t need any complicated framing…. really mixed opinions. Thanks again.

Find an architect that knows what they are doing One of the builders has warned you there will be engineering consequences at cost. Steel columns and lintels are required, lol but your architect has forgot to put them in. Goodluck with the variation engineering costs after you've handed over a deposit to the builder for the Preparation of Plans OT, Architects are good at Imagining structural elements, pity they aren't licensed to deal with them Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Silicone joint window- structural requirement? 7Jul 10, 2021 11:51 am amms moudzj Will need steel beams to pick up the bricks above - or, if the windows run floor to ceiling, maybe one steel, and one timber beam to support the roof.

Cheaper for you to ensure they do run floor to ceiling, because it would be quite complicated to pick up the brickwork if there is any above the windows/doors. Cantilever wont be possible in this instance, too big of a span.

My architect told me it will be around 4k extra for this window if we go with the silicone joint. He told me to check with a couple of builders, to get an idea (about cost) before we finalise the plans to avoid the shock later….BTW who is responsible for the structural drawings? I thought it is done by the structural engineer and the architect doesn’t have any role there(please correct me if I am wrong) Thanks again Re: Silicone joint window- structural requirement? 10Jul 10, 2021 12:33 pm amms StructuralBIMGuy amms Hi Moudzj, thanks for your comments.

Dont worry. Yes, seems like there is brickwork above the window, or maybe some lightframe cladding. How much extra would you be willing to spend to get this corner window done? Maybe also consider that if you did add a wall in the corner, youd have a point for some lightswitches for the living room in an ideal location.

LOL, here is the cost of the window? and to say check with the Builders is passing the buck. Good architects will provide you with engineering and construction details to pass on the builders.. that way everyone is on the same page... I've found Architects are very good at passing the Buck when problems arise and their FAKE RENDERING are first Class until you come to engineer/build it Forewarned is forearmed.

Thanks Chris, Yes, I wish he must be a bit more clearer in the first place. Based on the comments and advice here, I may drop that silicone joint part and go with a framed one….
