Planning a house extension to your property is a great move in the current environment. It is one of the most effective home improvements homeowners can make. Knowing where to start can often be difficult, however. That’s why we have put together this guide to help you on your way.
We’ve worked on a diverse range of projects over the years, and one takeaway is that, when planning a house extension, make sure you do your research. It’s amazing how many questions come up during our consultations.
Therefore, we are going to discuss some common questions that we get.
There are many different types of house extensions. This could be a basement extension, kitchen extension or even a new bathroom extension. They come in all shapes and sizes from a single storey to two storeys high and can be built using simple materials to more heavy-duty materials like bricks and structural glass. Check out some of our case studies by clicking the link here for some inspiration.
These are a set of statutory guidelines and minimum standards that are enforced by your local planning authorities. These regulations apply to any new builds that include house extensions. They take into account that the building work fits in with health and safety factors. However, be advised that it is a long and technical document, so we would advise that you refer any ideas regarding your plans to your architect or building contractor.
Typically the answer will depend on location and the type/sihttps://westernbuildingconsultants.com/wbc-services/planning-permission/?portfolioze of the extension, although there is leniency as long as you obey to certain criteria. This is because most properties gain from ‘permitted development rights’ (this has been in place since 1948), essentially allowing homeowners the right to extend their property without planning permission.
If you’re still unsure of what to do, make sure you speak to your local planning authority, typically the Council. However, if your property is a listed building or the property is located in a conservation area, then yes you will need to qualify for planning permission, before undertaking any work. Remember it’s a criminal offence not to do this prior.
Yes, to a certain extent, the extension cannot be higher than your own roof; however, there is no minimum requirement specified. With this being said, you need to be realistic, remember that you will be inhabiting the extension, and therefore it’s always nice to keep in mind that the normal ceiling height in the industry is about 2.4m.
Unfortunately, this is a very broad question, and it really does depend on a lot of factors. But we can give you a rough estimate. This excludes professional fees for your builder/architect. But typically you’re looking at £2,000 per m2. We recommend that once you have decided on what extension you’d like built, consult your architect or builder, and get plans drawn up. Once your plans have been created, contact as many builders as possible to get a general idea of what the project could cost.
The best way to assess if adding an extension will add value to your property is to speak to your local estate agent. Typically the answer is yes because you are adding more space to your property, which will result in added value.
If you’re serious and are looking for a more detailed plan, the RIBA Plan of Work is a great place to start. It organises the process into eight stages and offers great insight into stage outcomes, core tasks and information exchanges required at each stage. We are RIBA chartered ourselves, and if you live in the south west, and are considering building an extension, why not contact us!
Western were really professional, quick and went above and beyond to give us the designs we wanted as well as keeping us on track with our building plans. Thanks to James and all the team for the excellent work and affordable price.
Top notch service here from Paul Keegan who was super patient with us and when we finally got access for a building condition survey on our new premises, he went above and beyond the call of duty to get our report back to us over a weekend. Thanks WBC you came up trumps for us.
We want to say big thank you to western building consultants. We couldn’t be happier with everything they’ve done for us.
We are a small local building company that were looking for a similar sized company to work with us on many various projects from loft conversions and extensions to structural works of all sizes.
It’s been a relationship that’s worked great from day one. It’s been over a year now of working with western on at least a weekly basis. Whether its the office staff, architects or structural engineers they’ve been second to none. Always helpful and accommodating even throughout this pandemic which must of been a struggle.
I love that we can offer westerns services along side our own and the feed back we get from all of our customers when they’ve had contact with western is great.
In the 20 years I’ve been a builder this company is the best I’ve used and we will continue to use them for the next 20 years.

Exceptional service provided by Maria Simone; she incorporated as many of our requests as possible when designing a beautiful extension for us despite many limits and delays from the planning office. Her professional, thorough and friendly approach made us feel confident that we were in safe hands and we look forward to working with her and the rest of the team.
Have received a great service from Jo at Western Building Consultants so far. She is always very responsive, works extra hard for our tight timeline and kept me updated through out the process and was really quick to understand our project objective.
This is the third time I have worked with Western Building Consultants and as usual they have been a pleasure to work with. I dealt directly with Sam and Jo who did the Structural Calculations and the Drawings respectively for my residential to HMO conversion project. They were accommodating, engaging and professional.
I look forward to the next project!
I had a very positive experience with Western Building Consultants right from the start with requesting a quote from Ebony through to the delivery from Jo. Jo delivered exactly what i needed to a very good standard so much so that i’ve already booked in for another job. I wouldn’t hesitate to recommend WBC to others.
Our journey with Western Building consultancy so far has been fantastic! Jo’s patience and ability to understand my scribbles and ridiculous ideas made designing our venture fun instead of daunting. Communication is always prompt, professional and most importantly sincere. I’m really looking forward to how the rest of our project progresses!
I have enjoyed working with Western Building Consultants on a complicated project for about 4 years now. During that time they have without fail given me a high level of customer service, being welcoming, responsive and competent.
As a customer I particularly appreciate that WBC are value for money. They also stick to their quotes and don’t add a lot of extras. Help and advice is always forthcoming generally at no extra charge.
Thank you so much for all your advice today. That was so very helpful, not only with the structure of the property but especially with your comments about the whole set up. I can see that we were within a gnat’s whisker of entering a complete can of worms… Thank you so much for saving us from making a stupid mistake.
Thanks to you both your help in this matter – you were both extremely efficient and accommodating (more than I can say about other companies I contacted).
Your professionalism has been invaluable, thank you.
Thank you for your extremely comprehensive report. It will be of immense help when deciding on the works we would like to carry out on the property. We have decided to take your advice and move into the property and live in it for a while to assess our requirements.
Thank you for your prompt service, could not have asked or expected more. I note your comments and in an ideal world everything would have been 1.
Will not hesitate to recommend you, and will make a point of letting the estate agent know this too.
I just wanted to say thank you very much for your thorough and clear report. It is written in an informative and jargon free way which has made a pretty hefty document ultimately digestible and easy to understand.
Hello Kerry, Many thanks for the report and invoice receipt.
Please pass on my thanks to Paul for the survey. In my working life, I read many stock survey reports – I work with social housing providers to set up their asset management strategies – and this was one of the clearest and most comprehensive I’ve seen.
Dear Paul, Thank you so much for your fast response and the detail in your report is very very good and greatly appreciated. Thank you for your efforts.
Many thanks for your swift and thorough return of this report, we so appreciate you getting this back to us on such a tight turn around this week, and on the first read it seems extremely clear and comprehensive.
Hi Kerry / Paul, Thanks for sending the survey across.
I’d also like to thank you for your excellent service and professionalism. I considered many surveyors before choosing to proceed with you and it’s clear that I made the right choice. I won’t hesitate to recommend you to family, friends and colleagues in the future.
“We have commissioned three building surveys from WBC until we found the house that was right for us and all thanks to you”
I never expected so much detail, the report was really great and there were things I never even considered, even being in the construction trade
The report was brilliant and went into so much detail, having had reports from other surveyors in the past this report was far superior
“Highly recommended. Good customer service over the phone and by email. Very quick: from the initial phone call booking a site visit to me receiving the calculations took only 8 days.”
“We used James Dean …Western Building Consultants as an architect. Very good”
“Good surveyors & structural engineers that we used were www.westernbuildingconsultants.com
We were really happy with them, they came highly recommended by several people”
“Excellent service and help from the initial design/planning stage through to the end of all works”
“I can recommend Western Building Consultants. They are great on structural calculations, advice and technical drawings to whatever extent you want. We used them for advice and calcs for taking out our main load bearing wall downstairs. They were recommended several times over when we started looking.”
“Superb, professional, efficient, friendly, positive”
