What is 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.

Planning and building rules in Stevenage

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

We confirm whether your project is permitted development, needs prior approval or needs a householder application, and prepare the right submission.

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.
Pre-application advice from the council can help on sensitive sites.

What is a lawful development certificate?

A certificate from the council confirming that work is permitted development, which is useful when you sell.

Do I need a structural engineer?

For steels, new openings, lofts and extensions, yes. We arrange the calculations.

Can you visit a house in Stevenage to quote?
