How do conservation areas and Article 4 affect a drawing package in Blackheath?
How designation changes a Blackheath drawing package: Lewisham Council maintains 30 conservation areas, including Deptford High Street, Forest Hill, Hither Green. Inside any of them a Blackheath drawing package cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Hither Green sets the tone for Blackheath casework.
No blanket Article 4 over Blackheath: Lewisham Council has not withdrawn permitted development across Blackheath, so a drawing package outside a Blackheath conservation area usually keeps it. The £129 Lawful Development Certificate is still the document a SE3 owner wants on file.
What Blackheath is built from: Victorian and Edwardian terraces across Brockley, Honor Oak, Forest Hill; 1930s semi-detached in Catford and Hither Green; post-war mixed in Deptford. Generally permissive planning compared to central boroughs; loft conversions and side-return extensions routinely approved under PD. That mix decides the drawing package route in Blackheath more than the postcode does. Our fixed fee for architectural drawings in Blackheath starts at £840, against £1,750 for the Complete package that carries a Blackheath scheme through Lewisham Council planning and building regulations together.
What happens if a Blackheath property sits on a boundary?
- Southwark — the Southwark boundary runs against Lewisham, so a drawing package a street from Blackheath is decided by Southwark Council instead. Southwark runs 43 conservation areas across SE1 and its neighbours, which is why architectural drawings priced for Blackheath are re-checked against Southwark policy whenever the Blackheath address sits on that edge.
- Greenwich — cross the Blackheath boundary and Greenwich Council takes the drawing package instead, applying 20 conservation areas of its own around SE3. We re-price architectural drawings at the Blackheath edge because Greenwich policy and Lewisham policy rarely align on drawing package depth.
- Bromley — the Bromley boundary runs against Lewisham, so a drawing package a street from Blackheath is decided by Bromley Council instead. Bromley runs 48 conservation areas across BR1 and its neighbours, which is why architectural drawings priced for Blackheath are re-checked against Bromley policy whenever the Blackheath address sits on that edge.
- Tower Hamlets — adjoining Blackheath, with 58 conservation areas centred on E1. A drawing package on the far side of the Blackheath line is determined by Tower Hamlets Council, so the Blackheath quote for architectural drawings is checked against Tower Hamlets guidance before it is issued.
