Benefits of a detailed estimate

Improved Knowledge

If you have limited building experience, you’ll gain greater understanding of all the specific materials and labour time you’ll need to complete the work. You’ll have a realistic true idea of costs and above all be able to liaise with potential builders better knowing what is required.

Better decision-making

With a detailed set of materials and labour requirements, you’ll be confident in choosing the right builder to contract. You’ll spot anything physically missing that needs buying early. You’ll be able to decide what personal material choices need to be made as you go and when they need to be made.


With greater knowledge and decision-making breeds confidence. You’ll be able to discuss details with potential builders well and spot when things are not planned out or not being done properly. A large financial investment can be daunting and stressful and a detailed estimate and expert guiding you independently will ensure you’re always going in the right direction.
