How to Estimate Office Renovation Costs

By August 3, 2015Blog, Renovation Resources

One of the largest mistake building owners make is underestimating the renovation costs for their home, office, restaurant, or store. This can lead to very sticky situations, as once you’ve started a renovation project it’s difficult to stop, and it can be even more problematic to have decided to buy a house because you underestimated the renovation costs, only to get an accurate estimate and realize you’re in the hole for thousands of dollars.

If you’re planning on making renovations (or buying a building with the intention of renovating), make sure you can accurately estimate how much those renovations will cost. This includes both materials and labor, as well as intangibles such as not being able to use the room you’re renovating. If you’re doing renovations yourself, labor doesn’t cost you financially, but it still has the opportunity cost of taking up your time and energy. Additionally, doing renovations is a very physical process, and doing it yourself will make you fatigued and sore. Always have a 10-15% contingency to cover extra materials or additional variation work during the construction.

When estimating the cost of materials, make sure to account for things like missed items and breakage. And don’t just use the least expensive products in your calculations; figure out which materials you will actually use and price accordingly.

When estimating the cost of labor, get multiple quotes and check up on the contractors’ reputations. Some contractors will charge less but have a history of lower quality work, or billing for addition variation changes to cover the initial low cost. Hiring skilled, experienced contractors is essential to the success of your renovations. It is worth investing a little bit of extra money on reputable and experienced contractor teams, so you don’t need to stress out over the other items.

For example, an office renovation in Hong Kong can cost HK$510 per square feet and up. A 2,000 square feet space can range from HK$1,020,000 (at $510/sqft) to HK$1.92M (at $960/sqft).
