A loft room that works
A loft conversion can give you a bedroom, an en suite or a room to work in without giving up any garden. We work with you on the planning and drawings so the room turns out the way you picture it, and with over 15 years in the trade we can tell you what your loft will take.

Planning rules in Chelmsford
Planning applications in Chelmsford go to Chelmsford City Council. The council has 26 conservation areas, nine of them in the city itself, including Moulsham Street and the West End.
If your house is in a conservation area, such as Moulsham Street or the West End, a dormer or other roof extension is not permitted development, so the conversion needs a planning application. We tell you which route applies to your house.
Some jobs need a full application and some fall under permitted development. We tell you which applies before you pay for drawings, and build to your architect's and structural engineer's drawings.
Building control in Chelmsford
Building regulations are signed off separately from planning. Where your loft conversion needs building regulations approval, we book the inspections with Chelmsford City Council or an approved inspector and see it through to the completion certificate.
Questions about loft conversions in Chelmsford
How do I get a quote?
Whichever suits you best: call us on 07792 625391, message us on WhatsApp, or fill in our short enquiry form. We will arrange a time to come and see the property, then put a written quote together.
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.
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.
