Covering Dartford
Our coverage around Dartford (DA1) also includes Bexley (3 miles to the west) and Swanley.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What is included in architectural design and planning in Dartford?
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.
- Design options and 3D views
- Planning or lawful development certificate drawings
- Building regulations drawings and specification

Planning and building rules in Dartford
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 affect architectural design and planning?
- 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.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Architectural design and planning: common questions
Can I use your drawings with another builder?
Yes. If you buy drawings on their own, they are yours to use.
Do I need a structural engineer?
For steels, new openings, lofts and extensions, yes. We arrange the calculations.
Who deals with the council for a project in Dartford?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
