Party Wall etc. Act 1996 disputes in prime London property are rarely just about bricks and mortar—they’re often about amenity, timing, and disruption. One recurring scenario is where a building owner needs to rebuild a boundary wall (entirely on their own land), but requires access to the adjoining owner’s garden for several weeks—often during the summer.

So the question arises: is the adjoining owner entitled to compensation?

The Scenario

Imagine a typical high-value London situation:

• A dilapidated boundary wall needs rebuilding
• The wall sits wholly on the building owner’s land
• However, construction cannot reasonably be completed without access to the adjoining owner’s garden
• Access is required for 4–6 weeks during summer

Understandably, the adjoining owner may be concerned about loss of use of their garden—arguably at the most valuable time of year.

The Legal Position

The starting point is Section 8 of the Party Wall etc. Act 1996, which grants the building owner a statutory right of access to adjoining land where necessary to execute notifiable works.

However, that right is not unfettered.

The key compensation provision is found in:

Section 7(2)

“The building owner shall compensate any adjoining owner… for any loss or damage which may result… by reason of any work executed in pursuance of this Act.”

This is the critical hook: compensation is payable where “loss or damage” is suffered.

What Counts as “Loss or Damage”?

The Act does not define this exhaustively, leaving it to surveyors (under Section 10) to interpret in context.

In practice, this can include:

• Physical damage to garden features, planting, or surfaces
• Costs incurred (e.g. moving furniture, reinstatement)
• Loss of use of land, particularly where significant or prolonged
• Loss of amenity, especially in high-value residential settings

While “inconvenience” alone is not expressly compensable, the line between inconvenience and loss of amenity is often where awards are made.

The Summer Garden Problem

Timing matters.

In London’s premium residential market, a garden is not just land—it is a key lifestyle asset, particularly in summer months. Losing access for 4–6 weeks during this period can be materially different from the same works in winter.

As a result, surveyors frequently consider:

• The duration of occupation
• The extent of the area affected
• The seasonal impact
• The overall value and use of the property

It is not uncommon for awards to include a modest sum reflecting temporary loss of amenity, even where no physical damage occurs.

How Is Compensation Assessed?

This is not a strict formula exercise. Under Section 10, appointed surveyors determine disputes and will:

• Assess whether actual loss has occurred
• Consider reasonableness of the works and access arrangements
• Quantify compensation—often using a broad valuation approach

In practice, figures are often negotiated and may reflect:

• A weekly rate for loss of garden use
• A lump sum for disturbance and amenity loss

Practical Takeaways

• The building owner’s right of access is statutory—but not cost-free
• Compensation under Section 7(2) depends on demonstrable loss or damage
• In high-end London scenarios, loss of amenity during summer is often recognised
• Surveyors play a central role in determining both entitlement and quantum

Bottom Line

Yes—an adjoining owner may be entitled to compensation where access to their garden is required, even if the wall is entirely on the building owner’s land.

The legal basis is Section 7(2) of the Party Wall etc. Act 1996, but the outcome will ultimately depend on the facts, the impact, and the surveyors’ assessment of loss.
