House Extensions in Southend-on-Sea

SET Building & Brickwork builds house extensions in Southend-on-Sea and the surrounding parts of Essex. We price every job after visiting the property rather than over the phone.

Working with you

The extra space you have in mind

Before anything is dug, we sit down with you and go through what you want the space to do. We help with the planning and drawings, and with over 15 years in the trade we will tell you what works on your house and what will not.

Planning rules in Southend-on-Sea

Planning applications in Southend-on-Sea go to Southend-on-Sea City Council. The council has 16 conservation areas. In those with Article 4 directions, such as Clifftown, Milton and Shorefields, replacing windows or laying a hardstanding needs planning permission.

Some jobs need a full application and some fall under permitted development. We tell you which applies before you pay for drawings, build to your architect's and structural engineer's drawings, and book the building control inspections.

What an extension costs

Every job prices differently. The property, the specification and what we find on site all matter, which is why we visit in person before quoting rather than giving a figure over the phone.

Call us on 07792 625391 or send over your plans and we will arrange a time to come and look.

Questions about house extensions

How much does a house extension cost?

Every extension prices differently depending on size, specification and what we find on site, including ground conditions and drainage. We visit the property, look at all of it properly, then put together a written quote so you can see what is included.

Do I need planning permission for an extension?

It depends on your property, its position and what has been built there before. Some extensions fall under permitted development and others need a full application. We will talk you through which route looks likely before you commit to anything.
