I have also been building for 6 months now and generally have a good relationship with my general contractor. I can confirm that compared to last year, my house costs a total of 15 to 20 percent more. Because of this, my general contractor is still trying to grant my fixed price guarantee (unlimited), which in turn causes delays, materials being delivered late, or many services being carried out by his own people and no longer by additional subcontractors. Currently, for example, I am outsourcing one service, namely the roof completion (except for the already constructed roof frame)... so I can totally understand, tough times. I have also been building for 6 months and had the topping-out ceremony just about 2 weeks ago. I am keeping my fingers crossed for you that you find a solution and wish everyone else good luck with their construction projects!!!
