I'm thinking of having a full size pyramid built in the manor grounds?

I'm having my servants build a pyramid within the grounds for me for when I eventually shuffle off this mortal coil, only since I have told them they shall be buried along with me and all my earthly possessions once one pops one's clogs they seem to be on a permanent go slow. I of course have tried horsewhipping them into going faster but to no avail, any motivational tips for the wretched bunch.
