Building Design & Planning Services

about us

Using CAD drawings we will undertake the design of your home extension for planning permission and building regulations. This will also bring your idea to life and enable you to see how your new extension will look.

Our friendly, professional service is backed up with 25 years of experience within the building industry, which ensures we meet all of your needs and expectations.

As Local builders we are constantly working with local building authorities and know what they expect from us, this in turn makes the planning process a lot smoother.


 Our Free,  No Obligation Initial Consultation

At this stage we will listen to your initial ideas and requirements and discuss the most suitable, cost-effective extension for you and your property. We will also offer advice on the likelihood of approval from the local planning office.

 Survey & Design

The next step is for us to survey your home and produce drawings of what currently exists. This will then form the basis for the design of your new extension. We then prepare further drawings of your proposed extension based upon your ideas and requirements and present them to you for your approval. This is your chance to discuss any alterations you require.

 Submit Application

ATJ Building & Groundworks then submit the drawings to the local authority for planning permission and building regulation approval, which usually takes between 8 and 12 weeks. If any amendments are required we will discuss this with you and make the necessary changes and re-submit on your behalf.

 Application Approval 

Once planning permission is approved we will present you with 3 copies of the final drawings (planning permission and building regulation approved).
