New Build Drawings in Barnet
Fixed-fee, MCIAT-chartered new build drawings for Barnet homeowners — London Borough of Barnet validation and local constraints handled from the start.
Barnet's housing is dominated by interwar semi-detached suburbia across Finchley, Hendon and Edgware — homes ideal for hip-to-gable and dormer loft conversions and rear extensions, which frequently qualify as permitted development on semi-detached houses within the volume limits. But the borough also contains Hampstead Garden Suburb, one of the most tightly controlled residential areas in the country, so the correct route depends entirely on which part of Barnet you are in rather than on the house type alone.
Within the Suburb, an Article 4 direction removes almost all permitted development rights — one of the most far-reaching in London — and the Hampstead Garden Suburb Trust must also consent to external changes in parallel with the London Borough of Barnet. The borough's other conservation areas, Mill Hill, Monken Hadley, Totteridge and Finchley Church End, apply their own controls on 1930s semi character and front elevations, and the greens at Totteridge and Monken Hadley add further sensitivity. Elsewhere, Barnet's interwar semis usually retain permitted development rights for rear extensions and lofts.
We tailor Barnet applications to the specific area: straightforward permitted-development lofts and extensions across Finchley and Edgware, confirmed with a Lawful Development Certificate where they qualify, and carefully evidenced full applications within the Suburb and conservation areas. In the Suburb we handle both tracks — a design-led planning application to Barnet and the Trust's requirements — since approval there depends on respecting the Arts-and-Crafts character precisely. The fee is fixed and agreed up front, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Barnet approves. Drawing to the validation checklist, and turning drawings around in roughly seven days, keeps most householder applications inside the statutory eight-week determination, with the elevations and materials detail the council expects.
Planning in Barnet: what to know before you apply
The Hampstead Garden Suburb Article 4 direction is among the most far-reaching in London, controlling almost all external alterations and requiring Hampstead Garden Suburb Trust consent in parallel with planning. Elsewhere, Barnet's 1930s semis usually retain permitted development rights for rear extensions and lofts.

New Build Drawings for Barnet homes: the package and the process
Every new build drawings we prepare for a Barnet property is drawn to London Borough of Barnet’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Designing a new dwelling on an infill or backland plot in London is a longer and more technically demanding journey than an extension or loft conversion — it involves establishing whether the plot can support a new home at all, securing full planning permission against a borough's density, design and amenity policies, and then producing a building regulations and structural package detailed enough to actually build from. DrawingsDirect delivers all of this as one coordinated service: feasibility, full planning drawings, building regulations drawings and structural calculations, produced in-house rather than passed between separate architects, engineers and drafters who each need briefing and coordinating separately.
London infill and backland sites bring specific challenges that a straightforward extension does not: the impact of a new dwelling on neighbouring daylight and sunlight, privacy and overlooking, the character and density of the surrounding streetscape, and access, parking and refuse arrangements for a new independent home. Getting an early, honest read on these issues — before a full application is drawn and submitted — is often the difference between a scheme that is approved and one that is refused and has to be reworked. We assess feasibility and, where useful, prepare pre-application advice before committing to a full drawing set.
Is my plot suitable for a new build in London?
A feasibility assessment looks at plot size and shape, access, existing boundary conditions, relevant planning policy for the borough, and the likely impact of a new dwelling on neighbouring properties before any design work begins. Infill plots — a gap between existing buildings on a street — and backland plots — a garden or yard site behind existing houses, reached by a shared access — each raise different issues: infill schemes are usually judged on how well they match the scale, spacing and character of the street, while backland schemes are judged heavily on overlooking, garden loss for neighbours, and whether the access arrangement is acceptable. A feasibility study gives an honest view of whether a scheme is likely to succeed before you commit to full drawings.
What does pre-application advice add to a new build project?
Pre-application advice is a formal, paid process most London boroughs offer, where planning officers give written feedback on a proposed scheme before a full application is submitted. For a new build — where the principle of development itself is often the main issue, not just the design details — this feedback can be invaluable: it surfaces concerns around density, massing, daylight and sunlight or heritage context early enough to be addressed in the drawings, rather than discovered for the first time as a refusal reason months into a full application. We prepare and submit pre-application enquiries as part of the new build service where it is likely to strengthen the eventual planning application.
