RICS Level 3 Building Survey in Martlesham Heath

Our RICS Level 3 Building Survey provides an exhaustive examination of all visible and accessible elements of your property. We assess the main structural components including foundations, walls, floors, ceilings, and the roof structure. Our inspectors examine the condition of brickwork and blockwork, timber elements such as joists and rafters, and any signs of structural movement or deterioration. The survey includes a thorough assessment of the property's external appearance, checking walls, roofs, chimneys, gutters, and downpipes for damage or wear.

For properties in Martlesham Heath, where the majority of housing was constructed from the mid-1970s onwards, we pay particular attention to construction joints, cavity wall insulation, and the building envelope. The report includes detailed assessments of damp levels, timber condition, and the functionality of doors and windows. We identify any work that requires urgent attention and provide guidance on maintenance issues that could develop into more serious problems if left unaddressed. Our inspectors understand the specific construction methods used in this area's newer developments.

The survey also evaluates the property's insulation and energy efficiency, which is particularly relevant for homes in this area that may have been built to older building regulations. We check for adequate ventilation in roof spaces and sub-floor areas, as inadequate ventilation can lead to condensation and timber decay in properties of this age. The Level 3 report provides specific advice on improving energy efficiency where appropriate, helping you understand the costs and benefits of potential upgrades. This is especially relevant for properties at Brightwell Lakes and other modern developments that incorporate air source heat pumps and triple glazing.

Martlesham Heath was developed as a new village from the mid-1970s onwards, with properties built using modern construction techniques of that era. The predominant construction uses cavity wall construction with brick external skins, concrete foundations, and pitched roofs covered with concrete tiles. Many properties incorporate render finishes, which can be prone to cracking and damp penetration if damaged or poorly maintained. The development follows a traditional village pattern with a village green, pub, church, and cricket pavilion, creating a distinctive character across different phases of construction.

The local geology presents specific challenges for property owners. The underlying chalk bedrock is overlain by sand and gravel deposits and glacial tills, with surface soils consisting of fertile boulder clay or clay loam. This clay-rich soil is highly susceptible to shrink-swell behavior, expanding when wet and contracting during dry periods. This ground movement can affect foundations and cause structural issues, particularly in properties with large trees nearby. The British Geological Survey has warned that millions of homes are at risk of subsidence in the next fifty years due to climate change and shrink-swell, making this a significant consideration for IP5 3 property buyers.

Newer developments in the area, such as Brightwell Lakes by Taylor Wimpey, use contemporary sustainable materials including timber frame elements, wood fibre insulation, and modern heating systems. These properties incorporate air source heat pumps, underfloor heating, and triple glazing. These modern construction methods require different assessment criteria compared to traditional brick and block construction. Our surveyors understand the specific building methods used across different phases of development in Martlesham Heath and can identify potential issues relevant to each construction type.

The village also has heritage considerations, including the Grade II listed Martlesham Hall rebuilt in the early 19th century around an older timber-framed core, and non-designated heritage assets such as the RAF Control Tower and air-raid shelters at Martlesham Heath. While the main village dates from the 1970s, any older structures within the postcode area may require additional investigation during the survey process.

Martlesham Heath and the surrounding area face notable flood risks that any property buyer should understand. The village is located close to the River Fynn, with parts of The Street and Post Office Lane having a yearly chance of fluvial flooding ranging from low to high. The River Lark from Clopton to Martlesham, including Grundisburgh and the Bealings, is designated as a Flood Warning Area. Several surface water flow paths also traverse across Martlesham and into the River Fynn, creating additional pluvial flood risk.

During Storm Babet in October 2023, internal flooding affected approximately seven properties in Martlesham, demonstrating the real impact of severe weather events on this area. Properties in identified flood risk areas or those with a history of flooding face ongoing risk and may require specific insurance arrangements. Our surveyors check for signs of previous flooding, water staining, and flood resilience measures, providing advice on appropriate investigations and protective measures for properties in affected areas.

While Martlesham Heath itself is not directly on the coast, the nearby River Deben tidal estuary means the general area has coastal influences. The geology of the area, with its chalk bedrock and overlying sands and gravels, creates specific conditions for drainage and groundwater movement. Our inspectors assess how these environmental factors might affect the property and provide appropriate recommendations for any necessary investigations or protective works.

The population of Martlesham Heath stands at 2,731 according to the 2021 Census, with the ward showing significantly higher home ownership rates than the national average. This prosperous community, combined with the economic drivers of Adastral Park technology hub and the business park, creates strong demand for quality housing, making thorough surveying before purchase particularly important for protecting your investment.

Our experience surveying properties throughout Martlesham Heath and the wider Suffolk area has identified several recurring defect patterns that buyers should be aware of. Dampness remains one of the most common issues, particularly in properties where ventilation has been reduced by modern repair techniques aimed at improving energy efficiency. Poor ventilation in roof spaces and sub-floor areas can lead to condensation, damp penetration, and timber decay, all of which we assess thoroughly during the survey.

Structural movement related to clay soil shrink-swell is a particular concern in this area. The boulder clay and clay loam soils that dominate the local geology expand when wet and contract during dry periods, causing foundation movement that can manifest as diagonal cracking around doors and windows, sticking doors and windows, uneven floors, and gaps around joists. Our surveyors are trained to identify the tell-tale signs of this type of movement and will advise on whether a specialist foundation inspection is recommended.

Roof defects are frequently identified during surveys of properties in this area. Issues include inadequate ventilation in roof spaces, poor thermal insulation, blocked gutters and downpipes, and damage from fungal growth or insect infestation. Given that many properties in Martlesham Heath were built in the 1970s and 1980s, roofs of this age will be approaching or have exceeded their expected lifespan, making thorough assessment essential.

Drainage problems also feature prominently in our survey findings. Blocked gutters, poor ground drainage, and damaged downpipes are common contributors to damp and structural issues. The local geology, with its combination of chalk bedrock and overlying sands and gravels, creates specific conditions for groundwater movement that can affect properties in certain locations. We assess all drainage systems and provide recommendations for any necessary repairs or improvements.
