Overview

A Victorian townhouse, converted and extended.

The property is an upper floor period maisonette within a Victorian townhouse, converted from the top two floors. An extension had been added to the rear some years ago.

The buyer instructed a Level 3 Building Survey to ensure they understood the true condition before committing.

  • Major defects uncovered before legal completion
  • Critical safety risk identified: a non-conforming staircase
  • Complete clarity and confidence before exchange

Key findings

Hidden defects and a critical safety risk.

Four findings from the Level 3 Building Survey, from the main roof to the rear extension and the staircase.

  1. Finding 01

    Roof defects

    Significant roof defects, including slipped and missing slates to the main roof, with localised damage and inadequate underlay allowing rainwater penetration and potential water ingress.

  4. Finding 04

    Further investigations

    Additional areas of concern noted that will require further investigation, assessment and remedial works.

Outcome

£40,000Price reduction achieved

Armed with the findings, the buyer secured a £40,000 price reduction after the offer was revised to reflect the cost of the necessary repairs and upgrades.

Without the survey, these issues would likely have remained hidden until costly problems emerged.

“The Level 3 survey highlighted issues we would never have found ourselves. It saved us thousands.”
