Basement projects tend to involve a combination of excavation and structural interaction with shared walls. They require early planning because the statutory steps take time and cannot be rushed safely.
Which parts of the Act apply?
Basement projects commonly involve:
- Section 6 (adjacent excavation), and
- Section 2 (works to party walls/party structures), with notice served under Section 3.
Some basement schemes may also involve boundary wall issues under Section 1, depending on design.
The Party Wall process (Notice → Response → Award)
1) Notices
- Section 6 notice: at least 1 month before excavation
- Section 3 notice (for Section 2 works): at least 2 months before the relevant structural works
2) Response (14 days)
Consent keeps matters simpler. Dissent (or no response) triggers the Section 10 route.
3) Award if required (Section 10)
Where there is no written consent, surveyor procedures under Section 10 apply and an Award may be made.
Why basements need earlier party wall planning than most projects
Basements often have:
- deeper excavation and longer duration
- greater neighbour sensitivity (noise, access, risk perception)
- more complex structural sequencing
- more than one adjoining owner in terraces or multi-unit buildings
In straightforward terms: basements take longer, so neighbours typically want more certainty.
Common errors
- setting contractor dates before notices are served
- serving vague notices because design is still evolving
- assuming an informal chat substitutes for written consent
- under-estimating how many adjoining owners must be served
Helpful FAQs
Do basements usually require an Award?
Often, yes—because written consent is not always forthcoming and the Section 10 route is frequently used to conclude matters properly.
