New home extension on your mind for 2021? More key issues to consider....

Updated: Jun 16, 2023

Here on this blog – compliments of the excellent team - we at Mint Builders have been highlighting some of the numerous important thoughts and considerations for all home-owners planning a refurbishment or home extension for 2021.

We at Mint have been finding that here in Cheltenham and The Cotswolds more and more homeowners are planning extension projects to cost effectively improve the 'live-ability' of their properties in the face of the continuing quite desperate current COVID-19 crisis, which is forcing us all to be in their homes more and more .

vital matters

Thus far we have considered vital matters such as the new Permitted Development rules, Planning issues, Building Regulations, key design issues for a successful extension, the provision of services, thermal efficiency, drainage issues ..... and much more. In this third and final post we make a start with the key question of whether your current Water and Heating boiler can cope with your planned new extension.

new demands

For sure, adding a house extension could well mean that your boiler will be asked to do more work and current water systems being what they are, this could well mean it may not be able to deal with the new demands being made upon it.

You, of course, want both 'running' warmth and hot water – a cold home is in no way a more 'liveable' home that's for sure. This Winter warmth is surely more vital than ever before.

effectively heated

We at Mint can help you calculate just what any new extension of yours will need in order to be heated effectively. We understand and can guide you in terms of your current boiler output, the size of any extra radiators, hot water cylinder size and also ensure you have the correct re-heat times.


Another very important issue is to be confident how you and yours will manage while the work continues. Can you live 'on site' and manage the upheaval? Here again, we can advise on these issues and will always work in such a way in order to make life as bearable as we can for you while we develop your new extension.

better weather

These living upheaval issues must be considered with a view perhaps to now looking beyond the next three months or so and aiming for a Spring start date when hopefully the weather will surely more manageable.

restricted access

Also, the operation of your project can be affected considerably by your home's location. For example, if you live in a terraced home with restricted access, that may affect the options you have for your house extension design.


We at Mint can, of course, confidently advise you on such issues and we obviously are experienced in terms of developing and working in challenging operating build situations.

A key move is, of course, to put your neighbours in the picture right at the start and keep them informed as the project proceeds.


Remember, Mint, as your builder, may not be able to use certain construction methods, or we may need to make arrangements with your neighbours to temporarily remove fence panels or use their land for short-term storage. For sure, attentive neighbourly communication is without doubt the answer to a successful project being completed without upset, fall-out or hassle. And, of course, when the build is all over perhaps treat them to a bottle of wine or an even grander gift etc... to say 'thank you' for their understanding and good will during your project.

Finally a quite significant matter is the issue of the image of your new extension. This needs to be carefully considered in terms of how well your additional new extension space 'sits and presents' alongside your original property.

This 'look' will undoubtedly affect how you feel about the overall success of your project and could even affect the sell-on value too. While there are no hard and fast rules, you will need to carefully consider this matter and make a decision as to whether your new house extension should in general either complement or be in contrast with the main house.
