Loft Conversions in Brentwood
Turning unused roof space into a bedroom, office or bathroom, with the structural work, staircase and finishes handled by one team. Working in Brentwood and the surrounding area.
SET Building & Brickwork converts lofts in Brentwood and the surrounding parts of Essex. We price every job after visiting the property rather than over the phone.
A loft room that works
We look at the roof, the head height and where the stairs can go, then work with you on the planning and drawings so the room turns out the way you picture it. Over 15 years in the trade means we can tell you early what your loft will take.
- Head height and roof structure checked first
- Planning or permitted development confirmed
- Building control signed off at the end

Planning rules in Brentwood
Planning applications in Brentwood go to Brentwood Borough Council. The town centre is one of the borough's 13 conservation areas, and all of the countryside around it is Green Belt, 89% of the borough, where an extension is measured against the size of the original house.
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 a loft conversion 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 loft conversions
Will my loft convert?
It depends on the head height, the roof pitch and how the roof is built. We will look at the space and tell you what is possible, including whether the roof would need structural alteration first.
Do loft conversions need planning permission?
Many fall under permitted development, but it depends on the property, the type of conversion and the area. We will explain which route is likely for your house before you spend on drawings.
