What goes into architectural design and planning?
Designing and building under one roof means the drawings are priced as they are drawn, so there are fewer surprises when the quote arrives. If you only need drawings and a planning application, we can do that and you are free to use any builder.
- Measured survey of the existing house
- Design options and 3D views
- Structural engineer’s calculations

Do you need permission for architectural design and planning in Blackburn?
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 should I think about before starting?
- 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 are the steps?
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
