What is a set of architectural drawings?
Architectural design turns your ideas into drawings that a council and a builder can work from. It starts with a measured survey of the house, then design options, planning drawings and, once approved, detailed building regulations drawings and specifications.
How much does a set of architectural drawings cost in Lisburn?
In Lisburn, a set of architectural drawings typically costs £1,250–£3,750 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). That range is adjusted for Northern Ireland, where domestic building work typically costs around 14% below the national average. Council application fees are extra.

Planning and building regulations in Lisburn
Here is how the rules work for a set of architectural drawings in Northern Ireland. In Northern Ireland drawings are prepared for the council’s planning service and building control.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
Handled as part of most architectural drawings:
- Structural calculations coordinated
- Planning drawings: plans, elevations, site and location plans
- Measured survey of the existing house
- Design options and sketch layouts
- Tender-ready drawing pack
- 3D views on request
How long does it take?
Allow 2 to 6 weeks for drawings, depending on complexity. If the drawings are for a planning application, add the council’s decision period once they are submitted.
