Our Process

Neptune Construction provides you with a full design and build package. Meaning that we will do all the work for you. Initial Designs, Acquiring the Required, Permissions, Building and Finishing. Making the process as stress-free and simple for you as possible.

Have a look at how we do things in detail below.


Step 1

Initial Meeting

Get in touch with us and tell us what you want to do with your project, i.e. An Annexe, House Extension, Garage Conversion, Landscaping.

After this, we will book you in for an initial design meeting, where we'll come and visit your property and go over everything in a bit more detail. 


Step 2

Design Stage

We use 3D modelling software and animations to prepare your unique design to your specification.

We can include accurately sized people and furniture to give you a sense of scale, and kitchen layouts to assist in you better understanding what the design will achieve.

We offer you multiple designs so you can cherry pick the best of each, and you can add them to your final design. Just let us know what you are after and we will do the rest.

Step 3

Planning Permission and Building Regulations

If the house extension you are looking for requires planning permissions, we have a chartered town planner on our staff to assist with ensuring that the application processes as smoothly as possible.

Most construction projects then require Building Regulations Approval and in some cases a Building Over Agreement where sewers are within 3 metres of the build. 

Our projects team handle all of the above ensuring that you have all of the legal permissions in place for the build.


Step 4


From the foundations and drainage, damp proofing, walling and insulation, electric, heating and roofing - we will handle it all.

Step 5


Kitchen installations, bathroom design and build, feature lightning, tiling and flooring - we will get it all done to your specification.

The timescale largely varies from project to project, but you could see your new build done within as little as 10 weeks, depending on the type of development.
