Flat pack extensions: how to save money 

Every homeowner will need extra space in their home at some point in their lives. Most people think that moving house is the only option, when in reality there are many routes, you could go down. Flat pack extensions are a great way of adding extra space, and are way cheaper than a traditional extension or moving house. 

What is a flat-pack extension?   

A flat-pack extension is a home addition that is built off-site. Either in a workshop or a factory. Once it is constructed it’s delivered to your home, and then put together by the extension provider and a contractor.   

Just like a normal extension, there are many different styles of flat-pack extensions, for example:   

  • Steel  
  • Timber   
  • Brick    
  • uPVC   

How much do flat pack extensions cost? 

On average a flat pack extension can cost between £1260 – £1680 per square metre. A single storey extension (20 sqm) between £26,250 – £35,350. Including labour costs of £150 – £250 per person per day for roughly a week. Although, these prices don’t include fittings or finishings.  

Alterations to the main house –  

By adding an extension to your home, you will be making structural changes to the property. To ensure your home stays structurally sound, you may need to add steal support beams. You might need to hire a chartered surveyor to inform you of the condition of your property before the work.  

In addition, you’ll have to hire someone to install the plumbing, electric and gas before the extension is constructed  

How much cheaper are flat pack extensions compared to a traditional one? 

Flat pack extensions are the more affordable way to add space to your home. They can typically cost 25% less than a traditional extension. 

DIY –  

Whilst you could build your own flat pack extension, it might cost you extra if you make any mistakes. So, it might be best to leave the job to the professionals, as they are more skilled and experienced.

Architecture & Building, Planning Permission

Will you need planning to build an annex?  

What are annexes used for? 

An annex is a self-contained living space, usually including a kitchen, bathroom and bedroom. They are used because they provide more living space in a home. They can be built as an attached extension to your home or built as a separate building.  

What is the difference between and annex and an extension?  

An annex requires there to be at least 50cm of space between the boundary and the building. Whereas, an extension can be built closer to the boundary, when attached to the main building. In addition, even if the building is self-contained, if it’s attached to the main house, it will be classed as an extension.

Will you need planning permission? 

Just like any building work, you do need planning permission before you start building your annex. You would either need planning permission or a lawful development certificate from your local planning authority.  

If the building is considered to be a separate dwelling, you will need to apply for planning permission.

If you are converting an outbuilding into an annex, you would not require planning permission. You would just need to apply for a change of use.  

Do annexes add value to your property?  

Recent information from checkatrade reveals that on average, and annex will raise the value of your property by 20-30%.  

Where can I place my annex? 

If you are building a separate annex or as an extension, planning authorities usually insist on it being as close to the main house as possible. You also need to factor in amenities: electricity; water and sewerage, as these will also define your location. 

Can you turn your garage into an annex?  

Yes, you can turn your garage or other outbuildings into an annexe space. However, it is best to consult an architect as the building will need to be updated to adhere to the building regulations for a habitable building.
