At Earnock Builders we know that it should take time and consideration when deciding whether an extension or a new housing project is for you.

There are several aspects that you need to consider when undertaking a building project as it can take time from the day you decide you go ahead with it until the day of completion.

Here are the stages listed below:

Finding a plot of land for a new house build

An extension of the home won’t be affected by this stage of the process. If you’re looking for a new house build however, it can take time to find the exact location you want.


Once the project has been designed to your requirements the next stage is then submitting it to the local authority for planning permission. The standard time for a decision to be made is around 8 weeks, for more complex builds it can take longer.

For other small extension builds it might not need the go ahead from the council for it to get underway. However, it can take time to design and other building regulations may still need approval.

Building regulations

The planning drawings are only part of the design process. Further detailed drawings are needed for the approval of building regulators.  They go into more detail such as the type of materials used for the build and other specifications.

It can take several weeks for this part of the process to be completed as various parties may need to liaise with one another. The more complex the build, the longer the process.


Any good house builder needs booked in advance. It’s important to book with Earnock Builders as quickly as possible so we can start works on the project as soon as we’re available.

The size of the job comes into play here as well as the complexity of the project in terms of how long the project can take to be completed.  An extension depending on the size can take between 4-6 weeks while a house build considerably longer.

Changes to the design and the UK weather can add on time to the length of the construction process.


At this point, the job may have reached practical completion which means you’re able to move into your home. However, other little jobs may need completed at this time.  This may include tiling, or touching up paint.

The unexpected

Delays to construction can occur when ground conditions aren’t as expected what they should be. If an old existing building is getting works completed on it, it may have problems that become apparent once works start. This may include plumbing problems, structural defects or poor electrics.
