Through out the Costclick website you will see the word materials appear many times. It's meaning is quite staright forward - we are referring to the materials required to build your extension, such as bricks, blocks, roof tiles etc etc.


Materials obviously cost money, so it is important to get the right materials into your specification so the builders can quote as accurately as possible. When the builder is quoting you can ask them to quote on an all inclusive basis, this being including all labour, plant and materials to carry out and complete the work. if you have the time, you can ask the builder to quote on a labour and plant basis - this would allow you to shop around for the best prices on the materials to maximise the savings on your materials. If you decide to do this, make sure you either feel confident to 'quantify' the materials you require or see if your builder will help with this. Some builders merchants provide this service so they are always worth a call.

If you are going to manage the project yourself, you will be looking to break your project into trades, our detailed Budget Cost Calcualtor will help considerably, but some trades will traditionally supply their own materials, such as groundworkers and plumbers, while others, such as bricklayers and carpenters are labour and plant/small tools. You will need to liase with these tradesmen as to the materials they require.

Yet another option with materials, is 'ancilliary' or 'sundry' materials. These are often only small but essential parts of a building project, and if you are sending enquiry letters for labour only, ask them to supply sundry materials, and clarify what they have / have not included for the purpose of comparing their prices.

Some bricklayer Sundry Materials:

  • Wall Ties
  • Insulation clips
  • Frame ties
  • Lintels
  • Insulation
  • Sand
  • Cement

Some Carpenters undry Materials:

  • Nails
  • Screws
  • Glue
  • Bolts

Most tradesman will be more thanhappy to detail to you waht they have included and what they woudl prefer you supply.
