Completed project · Buckhurst Hill, EssexPlanning a loft conversion in Essex? Loft Plans handles the design and approval stage, not the build: measured survey, planning drawings, Building Regulations drawings, structural calculations and council submissions. You take the finished pack to the builder of your choice. We work across Epping Forest, Uttlesford, Brentwood, Chelmsford and the rest of the county from our base in Harlow.
Parts of Saffron Walden, central Chelmsford, Brentwood, Thaxted and the Epping Forest fringe sit inside designated conservation areas where Permitted Development rights are restricted — a full householder planning application is required even for a rear dormer. We check this for free before any drawings start and handle the submission and officer queries on your behalf.
The measured survey and drawings needed to define the design and support a planning or Lawful Development Certificate submission.
A selection from one completed Essex project for which we produced the drawings and planning package.

Before a builder can start, an Essex loft conversion usually needs four things settled: whether the loft is suitable, which conversion type suits the roof, which planning route applies, and the technical drawings and structural calculations for building control. • Suitability — head height, roof structure and staircase position • Type — dormer, hip-to-gable, L-shape, rooflight or mansard • Planning route — Permitted Development with a Lawful Development Certificate, or a householder planning application • Building Regulations drawings and structural calculations, prepared for building-control review We check your specific address and any previous extensions before drawing. Nearby areas such as Buckhurst Hill, Loughton, Epping and Uttlesford villages are well within our working area — see our Buckhurst Hill hip-to-gable project in the portfolio for a real example of the design package.
Essex homes — from 1930s semis in Brentwood to Victorian terraces in Romford and post-war houses in Basildon — almost all have great loft conversion potential. We assess head height, structure and access on the survey, then design a layout that suits your family and your roof. Dormer, L-shape, hip-to-gable and Velux conversions are all options we deliver routinely across the county.
We’ll assess the roof and explain what the space can realistically deliver.
Essex is covered by multiple planning authorities — each with their own conservation areas, Article 4 directions and local policies. We handle the paperwork end to end, including pre-application advice where it helps, and respond to officer queries directly so you don't have to.
The initial planning/design stage is £950 and covers the measured survey, drawings and relevant planning or LDC submission. For a full-planning case, a further £550 is payable after approval for Building Regulations drawings and structural calculations, making the coordinated package £1,500. Council, statutory and building-control fees are separate. For suitable Permitted Development projects, the technical package can be prepared within the same approximately 1–2 week design period.
We work across the whole county — here are some of the towns and villages we regularly design loft conversions in.
Yes. We provide loft conversion drawings, structural calculations and planning applications across the whole of Essex — including Brentwood, Chelmsford, Romford, Basildon, Billericay, Braintree, Witham, Maldon, Saffron Walden, Great Dunmow, Loughton, Chigwell and Epping.
After the survey, we prepare the planning or LDC drawings and submission in approximately 1–2 weeks. For suitable Permitted Development projects, the technical drawings and structural calculations can be prepared within that same design period. Full-planning technical work is finalised within a further few working days after approval.
Most loft conversions in Essex fall under Permitted Development, but conservation areas, listed buildings and larger dormers may need a full planning application. We assess this on the survey and submit the correct application for your council.
We regularly submit applications to Brentwood, Chelmsford, Basildon, Epping Forest, Uttlesford, Braintree, Maldon and Rochford councils, and handle planning portal queries on your behalf.
