If the builder has built it incorrectly according to the plans, then you are well within your rights to tell them to fix it.

You should stand your ground when it comes to the plans, because if there is something there that you overlooked or which they drew incorrectly and you didn't catch, they will not accommodate your requests.

As others have said, even if the brick work is finished and plastered if the door is not where it is shown on the plans you can demand that the builder fix the mistake even if that means demolishing that wall and starting again.

Would it be possible to make the benches on one side wider to make the door centered? the builder may agree to do this free of charge if the door is wrong and then you get the added bonus of extra wide bench tops.

I note you mentioned bricks are up.

So I'm guessing that when the plans were drawn they didn't consider the amount of bricks needed to actually centre the door in this space. It's a small detail that can be overlooked very easily but as you've found can be really annoying.

It could of possibly been avoided by changing that room width either a bit bigger or a bit smaller to allow the outside brickwork to line the door up in the centre (or something like that....). It is also quite difficult in some cases to have everything line up during construction but specific detailing like this can be shown on the plans which highlights to the builder and trades that special attention is needed in this certain area. Detailing such as this costs a lot more at the planning stage.

Bricklayers don't like cutting bricks so they go to the nearest brick/half brick rather than cutting every brick around an opening. Also cut bricks do look crap unless it's designed in feature brickwork.

Have a look at the brickwork on the outside and you'll see what I'm getting at.

Sounds like a good plan, hopefully the builder will agree to that. would be a lot easier for them than pulling down the wall so am sure they will be happy to do that instead..

I should of mentioned who's responsibility it may be.

Architect/building designer/draftsman - probably not as some clients don't care if it lines up equally or not, so if they don't be specific about a detail (can be any detail for that matter) then it won't be noted.

Builder - probably not as it wasn't noted on plan and/or there may have been a discrepancy during construction works.

Bricklayer - probably not as they work to 'brick dimensions', what has already been installed such as doors and windows for example and won't cut bricks unless there's no other option.

Other trades - probably not as it wasn't noted on plan and/or there may have been a discrepancy during construction works before they started their part.

Your solution does sound like a very good option however be it a corner pantry or other pantry. Maybe worthwhile checking over kitchen plans with kitchen manufacturer to be sure it's going to be what you're after too. Such as lining up sink or oven with new pantry/cabinetry/ fridge space/etc.

I think talk to your cabinet maker about your dilemma may be he has a solution. Cabinet makers are good at solving puzzles on space and gaps. It is only a dilemma in your eyes because you know it is not right and to you it stands out and always will that's a shame. But if the cabinet maker can reconfigure the cabinetry at that end like adding for instance a useful wine rack, a charging station, talk to him and make the builder cover the costs. Other than that you are going to have to change the opening knock out that side and order a new opening and honestly it will cause problems for a couple of days but then its done issue gone and you can move on.

Yes how2girl, it's almost no one's responsibility. It's a detail that can/is easily overlooked by almost everyone. It can be a trap for the unknowing client. Unless it's a specified detail on the plan then it's open to interpretation. The plans may pictorially show it's centred but if theres no actual measurement then everyone is in the clear.....

Full high quality Architects/Designers construction drawings would/should show this as a detail (amongst other little details) hence the higher costs of those plans. Standard Development Application and Construction Certificate plans rarely would show this or many other little details. I aim to line up openings for example as close as possible to centre (or wherever they need to be) by showing brick dimensions on the outside and a dimension on the inside but they are usually still a bit out either way on a brick veneer. A clad house is different as the cladding can be easily cut to suit the opening position. Bricks can be cut but look crap when theres a sliver of say 60mm with mortar around it.... Unless it's being rendered then the cut bricks can be hidden.....

Seems to be quite a few dilemmas about builders not following the plans. What are the council surveyors doing?
