Party Wall Surveyor Streatham

Planning a loft conversion, extension, basement or structural alteration in Streatham? Party wall requirements should be checked while the design is being prepared, before a contractor is ready to start.

Harding Chartered Surveyors advises building owners and adjoining owners across Streatham and nearby parts of SW16, including Streatham Hill, Streatham Vale, Norbury and the borders with Balham and Tooting. The area contains Victorian and Edwardian terraces, converted flats, mansion blocks, inter-war houses and newer developments, so the correct procedure depends on the building, ownership and proposed foundations.

The Party Wall etc. Act 1996 may apply to work directly affecting a party wall or party structure, a new wall at the line of junction, or qualifying excavation within three or six metres of a neighbouring structure. It does not apply to every extension or every wall close to a boundary. Drawings, title information and foundation depths should be reviewed before notice is served.

When might the Party Wall Act apply?

• Loft conversions: inserting steel beams or bearings into a shared wall.
• Rear and side extensions: building at the boundary or excavating below nearby foundations.
• Basements and underpinning: deeper excavation close to an adjoining building.
• Chimney-breast removal: cutting into or altering a party structure.
• New buildings: constructing a wall on or immediately beside the line of junction.

Party wall services in Streatham

Our service is tailored to the proposed work and the ownership position. We can review drawings, identify the relevant adjoining owners, prepare and serve the correct Party Wall Notice, record accessible areas in a Schedule of Condition and, where a dispute arises under the Act, prepare a Party Wall Award.

Party-structure notices normally require two months. Notices for a new wall at the boundary and qualifying excavation normally require one month. A notice generally remains effective for 12 months. For section 2 and section 6 notices, no written consent within 14 days normally creates a dispute and the surveyor appointment procedure can begin.

Both owners may appoint one Agreed Surveyor, or each owner may appoint a separate surveyor. Once appointed under the Act, surveyors must act impartially rather than as advocates for the owner who appointed them.

Guidance for building and adjoining owners

For building owners: seek advice while structural drawings are being finalised. Starting notifiable work before the statutory procedure is complete can cause delay, extra expense and possible court action. The Act has no retrospective notice process, so a notice served after work has begun does not correct the earlier failure.

For adjoining owners: receiving a notice does not mean you must object to the project. You may consent, consent after practical points have been clarified, or appoint a surveyor where a dispute has arisen. Appointed surveyors administer the Act impartially, regardless of which owner appointed them. Read our guidance for adjoining owners.

A Schedule of Condition provides a dated written and photographic record of accessible parts of the neighbouring property before work begins. If surveyors are appointed, the Award may cover construction methods, protection, access, working hours and procedures for relevant damage. It does not grant planning permission, determine every boundary dispute or replace other approvals.

Streatham projects and local property

Party wall questions in Streatham commonly arise with rear additions to terraces, loft conversions involving steelwork, basement excavations and structural alterations in converted houses. Ownership can be more complicated in flats and maisonettes because both freeholders and qualifying leaseholders may need to be identified.

Streatham includes conservation areas and many period properties, but planning or listed-building controls are separate from the Party Wall etc. Act. Obtaining planning permission does not remove the need to follow the Act where the proposed work is notifiable.

Excavation, safeguards and fees

Excavation is not notifiable merely because it is close to another property. The three-metre test depends on whether the proposed excavation will go below the neighbour’s foundations. The six-metre test uses a 45-degree line from the bottom of those foundations. Foundation drawings and available information about the neighbouring structure are therefore important.

Fees depend on the number of adjoining owners, the complexity of the design, whether access and a Schedule of Condition are required, and whether an Award becomes necessary. We provide a written scope and quotation for the actual project rather than relying on one headline price for every property.

Do I need a notice for a loft conversion?
Often, but not always. Notice is commonly required where steel beams are inserted into a party wall or party structure. The structural drawings should be checked before a notice is prepared.

Can my neighbour stop the work?
An adjoining owner cannot use the Act simply to prevent lawful work. They can require the statutory procedure to be followed and appropriate safeguards to be agreed or determined.

What happens if my neighbour does not reply?
For section 2 and section 6 notices, no response within 14 days normally creates a deemed dispute. A further request to appoint a surveyor is then served before the statutory appointment process continues.

Can one surveyor act for both owners?
Yes. Both owners may appoint one Agreed Surveyor, who must act impartially. Otherwise, each owner appoints a surveyor and those surveyors select a third surveyor.

Who usually pays the surveyors’ fees?
The building owner carrying out the work normally pays reasonable costs arising from the statutory process, although the Act allows costs to be allocated differently where the circumstances justify it.

How much does a party wall surveyor in Streatham cost?
Fees vary with the work, number of adjoining owners, access, condition recording and whether an Award is required. We provide a written quotation based on the actual project.
