New Build Drawings in Forest Hill SE23
Fixed-fee, MCIAT-chartered new build drawings for Forest Hill (SE23) homeowners — London Borough of Lewisham validation and local constraints handled from the start.
Forest Hill (SE23) in Lewisham is a hilly Victorian suburb of substantial villas and terraces around the Horniman Museum and gardens. The steep topography and the Forest Hill conservation area together shape what works for extensions and loft conversions here.
Within the conservation area an Article 4(3) direction removes specified permitted development rights, so many changes that would be permitted elsewhere need a full application designed to the area's Victorian character; the steep plots add overlooking and level-change considerations. Lewisham's small-HMO Article 4 direction is a further control on conversions.
Planning in Forest Hill (SE23): what to know before you apply
The Forest Hill conservation area carries an Article 4(3) direction removing specified householder permitted development rights, so loft and extension projects within it generally need a full planning application rather than relying on permitted development. The steep hillside plots and mature trees around the Horniman add design and TPO considerations, and Lewisham's small-HMO Article 4 direction restricts new conversions.
Typical Forest Hill housing stock
Substantial Victorian villas and terraces climbing the hills around the Horniman Museum, with later Edwardian and interwar houses on the higher ground toward Honor Oak.

New Build Drawings for Forest Hill (SE23) homes: the package and the process
Every new build drawings we prepare for an Forest Hill property is drawn to London Borough of Lewisham’s validation standards and tuned to the SE23 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.
