If the necessary planning permission has been obtained and building regulations approved by your local authority, then an extension should increase the value of your home. If the work has been carried out professionally then it could potentially add thousands onto your home's value.

For example, research carried out by the Nationwide Building Society showed that a bedroom extension with en-suite had the ability to add up to 23% value of a property. A kitchen or bathroom extension typically added 6% to the value or more. 

It’s also worth noting that not only does an extension increase the value of your current home, it also makes living there much more comfortable and enjoyable.

The rules surrounding whether or not your home extension requires planning permission can be quite complex. At JM Building we are happy to help discuss your project and advise on what is required.

Typically planning permission isn’t required provided you meet certain requirements. These include your extension not being more than 50% of the size of your house and the roof and eaves being lower in height than those of your existing property. The extension must be built on the rear or side of your property (not the front). Also, the materials used to build your extension should be similar to those of your house so that it doesn’t ‘stand out’ too much.

Whilst there is no law requiring you to appoint an Architect, JM Building would certainly recommend using one as an extension to your home is an important investment, and deserves experienced and professional attention. 

An architect will help ensure your house extension is safe and legal, and be able to keep you up-to-date with architectural trends, provide ideas you’d possibly not considered before and produce drawings necessary to show your local authority Building Control and Planning teams. 

Technically the only limits are your land, budget and any local authority restrictions. At JM Building we have a highly skilled and qualified in-house team to build your dream home extension and are fully insured to undertake projects of any size.

Yes. Once you have accepted a quote from JM Building a Trade Coordinator and a Project Manager are allocated to run your project. Together they will manage all aspects of the build. 

The first step of the project is to get your quote drawn into a contract. We then will build a Programme of Works, conduct pre-construction site meetings with the relevant trades and arrange a site set up to comply with health and safety regulations. 

You will have regular meetings with the Project Manager and Trade Coordinator which allows us to discuss the progress of the project and next steps. Your Trade Coordinator will arrange relevant meetings and inspections with your appointed Building Control Inspectors right through to obtaining your final certificate of satisfactory completion for Building Regulations and any other necessary certificates such as electric and gas safety.

We certainly do and would be happy to share them with you. Our website offers just a glimpse of the work we have carried out over the past few years. We’ve used professional photography as much as possible for this showcase, but we have plenty more example photos we can show you to give a wider example of the work we have completed.

We follow a valuation process which ensures that you do not pay for any work until each stage is completed and signed off by the Project Manager and you can see exactly what you are paying for, how much is left to pay and at what stage of the project payments will be due

Payments can be made by BACs, debit card and even credit card allowing you to spread the cost of your project over a period of time
