Should I Extend My Home or Move to a Bigger One?

April 8, 2019

To Extend or To Move, That is the Question.

For many, the idea of undertaking construction work can be daunting. Having your house pulled apart and altered can be worrying with so much to consider. Moving on the other hand has more certainty about it, you see a house, like it, buy it and move in, simple!

In this blog we will consider some of the positives and negatives of each scenario.

Shall I Extend My Home?

When considering whether to extend your home, there are many factors that you will need to consider. This include (but aren’t limited to):

  • Money; do you have enough to undertake the works? Do you need a larger mortgage?
  • Time; do you have time to devote to the project or will you need someone else to manage the process?
  • Space; do you have enough space to extend into? Do you own that space?
  • Planning permissions; in some areas such as a ‘conservation area’ you can not build to what is known as permitted development and will need a full planning application.
  • Architects; many will require an architect although some builders will offer a ‘design and build’ option where they will deal with everything.
  • Engineers; you will need someone to design the structure of your extension, remember an architect only designs what the extension will look like.
  • Other professionals; party wall costs, building control, heating engeineers, kitchen fitters etc.
  • Builders; finding the right builder can make or break a project.
  • Temporary accommodation; will you live in your property during the works or rent elsewhere?

Remember, you will need to spend money as well as time on a project and this should not be discounted.

So what are the pros and cons?

The pros can include:

  • Not having stamp duty tax to pay on moving house. This can be many tens of thousands of pounds.
  • Staying in an area you love whilst having a larger home.
  • Designing the extension of your dreams.
  • Potentially increasing the value of your home, often to a greater extent than the money invested in the extension.
  • Having another bedroom/s.

The cons can include:

  • Larger mortgage re-payments.
  • Potential for things to go wrong such as structural damage or damage to neighbouring property.
  • Having a poor builder or one who may try to charge additional sums.
  • Stress.
  • Time overrun meaning over spend. For example if you are renting in the meantime, every additional month can mean more mortgage AND rent payments.
  • Hidden costs that were not planned for such as different ground conditions, drainage problems or other oddities that pre-exist.

Shall I Move?

So we know that there are complexities that come with extending your home but what about simply moving to a bigger home? Well there are obvious benefits such as the immediacy of having a larger property but what are the pros and cons in this scenario?

The pros can include:

  • Larger living space.
  • Larger garden.
  • More up-to-date living accommodation if refurbishment has already been undertaken.

The cons can include:

  • Stamp duty tax payment.
  • The costs of moving including removals companies, agents fees and lawyers.
  • The potential that you will need to move to a new area to afford a larger house.
  • Larger mortgage re-payments.


As with any big decision, there are always pros and cons. In order to make a decision whether to move or extend you will need to consider a whole host of factors with money being near or at the top. If you cant afford to move or extend, don’t it is expensive and your home could be re-possessed if you do not make repayments on your mortgage.

If you can afford to extend or move, you will need to start planning; which is better?; why?; when shall we do it?; how big shall we go?
