Important points when considering a house extension 

If you and your family need more space, then home extensions are a great way of doing this without the stresses and upheaval that selling your house and moving can come with. It can also be a much less expensive option to gain extra space and can add value to your home. When considering an extension, it’s important to think about exactly why you would like one and what you want from it. 

What type of extension would you like? 

Some of the more popular options include:

Extension over an existing garage: These can come with some risk as building an extension over an existing garage needs careful planning due to the existing structure and open space below it. Special attention should also be paid to the type of roofing. You may have to park your car elsewhere during the work or put it at risk of accidental damage.

Two storey extension: Keep your surroundings in mind and the impact that it may have if you have neighbours near to your property, as the size of the extension and proper ventilation that it needs may affect the neighbouring properties view and the light that reaches their homes. If planning permission is needed then it is worth letting them know personally that you intend to carry out the works to avoid any issues. 

Rear or single story: This is the most popular choice and can take up one story or can be built on the side or rear of the property. It’s the most common choice because it can be easily built onto the existing garden or outside space in the form of a sun room or kitchen extension for example and can really open up the home. 


Set your budget

Take into consideration how much you can spend as you can increase the value of your home with a relatively modest outlay. Put together a list of everything you would like so that you can discuss it all in detail with your builder and get as accurate a quote together so no one has any surprises. Then it’s worth setting aside a bit extra – as much as 10% – as there’s more often than not some unexpected costs that will appear along the way.

Planning permission

Check if you need planning permission as, depending on the type of building works, different regions may have different laws regarding development rights. There can be height restrictions, noise considerations and also hours of work that can differ between councils. Always make sure you have the correct paperwork available should you get a visit from the building inspector.

Your neighbours

If you have neighbours close to you, then you need to think about them too. Contact them in advance and let them know of your plans, so they will be less likely to object if they are given the opportunity. It might be worth inviting them over to your house to show them where and what you intend doing so they can get a good understanding of what exactly will be done. 


Make sure your builders are trusted and reliable tradesmen who are certified and are correctly insured for the works. As well as your builders having the correct insurance, you will need to contact your insurance company to verify you have everything in place and to make them aware of your plans as this may have an affect on your premiums. 

Be realistic

Chose materials carefully to ensure that they complement the existing property and that the size and dimensions of the project don’t overwhelm the rest of the home and take up more space than you’re willing to lose. Think about the impact it will have on your home and visibility. If for example, you are having large glass windows installed to create more space and light, then bear in mind if this will make you more exposed.

Also think about the time of the project and how it will affect your living there. You may chose to go away for the length of the works or to be away partially, depending on how much disruption the work will cause. If you will be staying there then then make sure you close off areas of the house that you don’t want to be accessed. This will also help keep it secure from any dust and unwanted attention. Also, it’s a good idea to have an access plan for the builders so they can come and go easily and have as little an impact as possible on your day to day living.
