Covering Blackheath
We work in Blackheath (SE3) and the places around it, including Greenwich, Catford and Eltham.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
What goes into architectural design and planning?
Architectural design and planning covers everything before building starts: a measured survey of the house, design options, planning or permitted development drawings, the application itself, building regulations drawings and structural calculations. We offer it on its own or as part of a design-and-build project.
- Measured survey of the existing house
- Design options and 3D views
- Structural engineer’s calculations

Planning and building rules in Blackheath
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
We confirm whether your project is permitted development, needs prior approval or needs a householder application, and prepare the right submission. A lawful development certificate is the best proof that permitted development work is lawful.
What can change the price or programme?
- Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
- Conservation areas and listed buildings need extra design care and supporting statements.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
