Weather Changing ?

From the weather forecast the weather looks to be changing.

Next week the weather might not be so nice as the past 4 weeks.. I wonder what impact this has on the construction progress?

so since March 10th.. house 7 has been under construction by BIK Maison / Woningen.

looks like until this is finished, then BIK maison / Woningen will start on house 8. Which means no progress will be made on house 8 for another few weeks - but the foundations were completed at the start of March.. so for 2 full months, no further progress on that house.

the roof timber for house 7 was delivered 2 weeks ago.. there must be another 2 - 3 weeks of brick work left.. so does this mean they are already 1 month behind house 7?
