4 Extra Construction Costs You Need to Factor

Loft space is one of the most ignored places in our house that we only use for storing old and junk items. But, if you convert the loft or attic of your house into a clean bedroom, office or gaming room, it can provide you with some extra usable space in your house. You may decide to extend the kitchen or build a conservatory to create more space, these are all big jobs and require serious thought. 

Now, converting the loft into a bedroom or extending the kitchen is not an easy job. It needs a lot of planning. It is like restructuring a part of your house from scratch. You need to hire an architect, get the planning permissions, decide your budget, and consider many other factors.

Focusing on the budget is important, there are some construction costs that need to be analyzed properly before investing. Let us dive into the construction costs that you need to factor before investing.


Scaffolding is defined as the structure that is built around a building to provide a platform for workers for cleaning, building, or maintaining the building.

Now, if you live in the UK and extending your home, scaffolding is an essential part of it. Moreover, there are numerous things that govern the overall cost of the scaffolding. The cost of scaffolding may vary from £40 to £150 in the UK. Here are some of the factors that govern this cost:

  • Length of hire: Total time for which the scaffolding is required.
  • Location: The location of the house plays a great role in deciding the cost. For example, the prices of scaffolding in Essex are much lower than in London, so pick who you choose to use wisely.
  • Height:  If the height of your home is more, the requirement of poles and wooden planks will also be high. Hence, more cost.
  • Dimensions: The dimensions of your attic will also hike the cost.
  • Ease of access and others: If you house if easily accessible for the builders, the cost will be low and vice versa.

Utility Cost

In the list of loft conversion costs, there is a utility cost that covers all the necessary utilities that are needed in the loft. It is pretty obvious that we never pre-plan the attic part of our house.

So, if you are converting your attic into a bedroom or gaming room, you need to make arrangements for utilities like plumbing, electricity, gas, heating, etc. You may also need to get the electrical system of your house upgraded or newly installed if you are extending your living space.

Using stainless steel sheets for roofing can prevent decay of materials because of their leak-proof characteristics, saving you money in the long run.

The cost of such utilities cannot be decided before the project begins. First, you need to get the permissions based on your loft conversion preferences. Post this, when the conversion of your loft or attic starts, you can estimate the cost of utilities. Hence, you need to save some part of your budget for the utilities.

Skip Rental

It is pretty obvious that there will be a lot of debris and waste when your loft will be converted into a bedroom. The waste could be in the form of wood, concrete, glass, etc.

Midi skips: The midi size skip is equivalent to around 35 wheelie bean bags. It can be used for medium-sized projects. The dimensions of this skip are Length 1.83m x Width 1.29m x Height 0.97m.
