Party wall surveyor in High Wycombe

Show level changes on the excavation section

For a project around High Wycombe or Marlow, a site with different ground levels needs more than a flat foundation plan. Show where the new excavation sits in relation to the adjoining building and any retaining structure. A section through the closest point is often particularly useful. Explain whether the new works include a retaining wall, underpinning or alterations to an existing shared wall, so each operation can be assessed on its own merits.

What to send for a High Wycombe enquiry

• Provide a section through the closest adjoining structure and proposed excavation.
• Dimension relevant changes in ground and foundation levels.
• Identify existing and proposed retaining structures separately.

Include the property address, the intended start date and any notices, responses or awards already issued. We advise in High Wycombe, Marlow. This is a service coverage page; it does not claim a separate office in each town.

Is a retaining wall automatically a party wall?

No. Its position, construction, ownership and relationship to the buildings matter. Excavation or alterations may raise separate issues under the Act. A surveyor needs the site detail rather than a label applied to the wall.

Choose the right party wall service

If you are carrying out work, our building owner service starts with identifying the notifiable operations and relevant adjoining owners. If you have received a notice, our adjoining owner service can help you understand the proposal and your response options.

Where a dispute arises under the Act, the owners can consider an agreed surveyor or separate appointments. A party wall award records the relevant statutory decisions and conditions; it is not the same as planning permission.

Fees and timing

See our party wall fees and guidance for the published service prices, shown + VAT where applicable. Confirm the scope for the particular project before appointing. The notice period and time needed for a response or award depend on the provision used and the circumstances. Allow time for the process before arranging the relevant works.
