For most women, this is a personal decision. Legally, if you are using FMLA leave, you may take time off at any time during your pregnancy or even after childbirth (within 1 year of your child's birth). Some women work right up until they go into labor whereas others decide to start maternity leave before giving birth.
The average price of a steel barn will depend on the size you need and the style of building that you choose. Barns are available in both the straight wall system as well as the arched (or Quonset) style. Straight wall barns cost between $7 and $25 per square foot.
More sophisticated pole barn kits cost around: $30,000 to $40,000 for a 1,500 square foot barn with a porch and loft or comparably sized pole barn houses (cottage style). $50,000 to $60,000 for a 2,500 square foot RV garage barn with a loft and porch.
