House Extensions in Upminster
Extensions designed around how you use the space, built by a team that handles the whole job from start to finish. Working in Upminster and the surrounding area.
SET Building & Brickwork builds house extensions in Upminster and the surrounding parts of Essex. We have worked on lofts in Upminster and in Bulphan, just up the road. We price every job after visiting the property rather than over the phone.
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 and drawings sorted before we start
- Building control inspections booked
- A written quote, priced from a site visit

Planning rules in Upminster
Planning applications in Upminster go to London Borough of Havering. In the Hall Lane Policy Area a planning application has to include a survey of the trees and shrubs on the plot. Corbets Tey and Cranham are conservation areas.
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.
