Buying a Property Near Mature Trees: Should Cracking and Subsidence Concern You? Mature trees can make a residential street or garden considerably more attractive. They provide shade, privacy, wildlife habitat and a sense of established character. Their presence does not mean that a property is suffering from subsidence. Equally, trees should not be dismissed where cracking, distorted openings or a history of structural movement exists. The correct assessment depends upon the

Buying a 1930s House: Which Defects Commonly Require Further Investigation? Houses constructed during the 1930s form a substantial part of London and suburban housing stock. Many provide generous rooms, bay windows, front and rear gardens and practical family accommodation. They are often described as traditionally built, but age, maintenance and decades of alteration can create significant differences between apparently similar properties. A house may retain most of its orig

Buying a Top-Floor Flat With a Roof Terrace: What Should You Check Before Exchange? A top-floor flat with a private roof terrace can be one of the most attractive forms of London accommodation. Elevated outdoor space, natural light and views can add considerable enjoyment and value. However, a roof terrace is more than a balcony or landscaped garden. It is an occupied area constructed above another part of the building, often directly over living accommodation. Its performanc

Buying a Ground-Floor Garden Flat: What Problems Should a Survey Reveal? A ground-floor garden flat can offer advantages that are difficult to find elsewhere in London. Direct access to outside space, fewer internal stairs and accommodation opening onto a garden can make these properties especially attractive. However, their position at the base of the building creates particular risks. External ground levels, drainage, dampness, suspended floors and rear additions can all af

Buying a Recently Refurbished Property: What Defects Could Be Hidden? A recently refurbished property can be extremely attractive to a buyer. New kitchens, modern bathrooms, fresh decoration and contemporary flooring may suggest that substantial expenditure will not be required after completion. However, refurbishment can improve appearance without resolving the condition of the underlying building. In some cases, new finishes conceal dampness, cracking, defective services or

Buying a House With a Rear Extension: What Should Your Survey Investigate? Rear extensions are common throughout London. They can create larger kitchens, open-plan living areas and valuable additional accommodation. A well-designed and properly constructed extension can enhance a property considerably. However, the new structure must interact successfully with the original house, adjoining property, drainage, external ground and roof. Fresh decoration and modern finishes do n

Buying an Ex-Local Authority Flat: Why Is a Detailed Survey Important? Ex-local authority flats remain an important part of London’s housing market. They can offer generous rooms, practical layouts and locations where equivalent privately developed properties are considerably more expensive. However, the expression “ex-local authority” does not describe one form of construction. The property might be within a traditional brick-built block, a concrete-framed estate, a low-rise

Buying a London Maisonette: What Should a Level 3 Survey Examine? Maisonettes are found throughout London in converted houses, purpose-built blocks and post-war housing estates. They often offer more internal space than a conventional flat, sometimes arranged over two floors with a private entrance, garden, balcony or roof terrace. However, the word “maisonette” describes the arrangement of the accommodation rather than its construction. One maisonette may occupy part of a Vi

Defective Building Work: When Is Repair No Longer Enough? Not every construction defect requires complete replacement. A loose tile may be refixed, an isolated plumbing joint replaced and a local crack repaired once its cause has been established. However, repeated patching is not always economical or technically reliable. Where defects are widespread, concealed or linked to the underlying design, another local repair may merely postpone substantial reconstruction. The correc

When a Boundary Inspection Found No Encroachment Boundary surveyors are sometimes instructed by an owner who is convinced that a neighbour has built across the boundary. A new wall may look wider than its predecessor or appear inconsistent with the title plan. However, an investigation should not assume that encroachment occurred. The surveyor’s role is to assess the documents and physical evidence objectively. Sometimes that evidence supports the owner’s concern. In other ca

Vertical Boundary Disputes in Converted Properties: Where Does One Flat End and the Other Begin? Boundary disputes are not confined to garden fences and dividing walls. In a converted house, flats may occupy separate floors while sharing roofs, structural walls and service routes. A dispute can arise when one owner uses a roof space, alters a floor or installs services through a ceiling void. The question is then not where the boundary lies across the ground, but where one pr

Defective Building Work: What Evidence Should You Preserve Before Repairs Begin? When defective building work is discovered, the natural response is to arrange repairs quickly. However, removing or covering it before it has been recorded can destroy important evidence. If responsibility, causation or cost is later disputed, the original arrangement may be impossible to reconstruct reliably. Evidence should therefore be preserved before repairs begin wherever it is safe and re

Party Wall Schedules of Condition: Do Both Surveyors Need to Attend? A schedule of condition is commonly prepared before notifiable work begins under the Party Wall etc. Act 1996. It records the visible condition of relevant parts of the adjoining property through written observations and photographs. If damage is reported during or after the work, the schedule helps the owners and surveyors establish whether it was already present. Where each owner appoints a separate survey

Buying a 1960s Concrete-Framed Flat: What Should a Level 3 Survey Examine? Flats built during the 1960s can offer generous rooms, large windows and convenient London locations. However, their construction may differ substantially from that of a traditional brick-built house. Some blocks have reinforced concrete frames and floors enclosed by brickwork, panels or lightweight cladding; others used proprietary systems. A purchaser should not assume that every concrete-framed bloc

Damp in a Cellar: Rising Damp, Penetrating Damp or Poor Ventilation? Dampness is commonly encountered in cellars beneath Victorian and Edwardian houses across London. Many were constructed for storage rather than as dry habitable accommodation. Their walls may be in direct contact with surrounding ground, and the original construction may contain little or no effective protection against moisture penetration. The presence of dampness is therefore not always surprising. Howeve

Can One Party Wall Surveyor Act for Both Owners? When a dispute arises under the Party Wall etc. Act 1996, the building owner and adjoining owner do not necessarily have to appoint separate surveyors. The Act allows both owners to agree upon the appointment of one person, known as the Agreed Surveyor. This can reduce duplication and costs, but is suitable only where both owners accept the surveyor’s independence and ability to act impartially. What Is an Agreed Surveyor? An A

Buying a Converted London Flat: Seven Issues Buyers Commonly Overlook Converted flats form a significant part of London’s housing stock. Many were originally Victorian or Edwardian houses and were later divided into separate dwellings. They can offer generous rooms, period features and homes within established residential areas. However, a conversion introduces considerations that do not usually arise when buying a conventional house. The purchaser is acquiring an interest wi

Case Study: Cracking to the Rear of a Victorian London House Cracking is frequently encountered during surveys of Victorian houses across London. It may result from historic movement, ageing materials or relatively minor changes within the building. However, cracking should not be assessed solely by its width. Its position, direction, distribution and relationship with the building’s construction are often more important than the measurement of an individual crack. This anony

Party Wall Notices for Rear Extensions: When Is a Notice Required? Rear extensions are among the most common residential building projects undertaken across London. Although the design may appear straightforward, the work can engage several provisions of the Party Wall etc. Act 1996. An extension may involve building at the boundary, excavating beside a neighbouring property or carrying out work directly to an existing party wall. In some cases, more than one type of notice w

Buying a London Flat With a Flat Roof: What Should a Level 3 Survey Examine? Buying a top-floor flat in London can be attractive. These properties often benefit from good natural light, greater privacy and freedom from noise caused by occupants living above. However, where the flat is immediately beneath a flat roof, the roof’s construction and condition require careful consideration. Defects can cause water penetration, deterioration of concealed materials and substantial se
