Measured Building Surveys
Measured building surveys provide accurate information about a building’s layout and structure, supporting design, refurbishment and compliance. We produce traditional plans and elevations, BIM-ready models, conservation-grade heritage records, area measurement surveys and fire safety plans. All surveys are carried out carefully and methodically to give clients dependable, project-ready information.

Established 2003
David Cosby Chartered Surveyors have over two decades of experience providing accurate and reliable measured building surveys for projects across Northamptonshire, from traditional plans and elevations to BIM-ready digital models and conservation-grade recording.
Plans, Elevations & Sections
Measured building surveys form the basis of most design and refurbishment projects. We produce accurate floor plans, elevations and sectional drawings that reflect the true layout, structure and proportions of a building. These drawings support planning applications, architectural design, building control submissions and contractor tendering. All surveys are carried out with a careful, methodical approach to ensure reliable information from the outset.

Technical Expertise You Can Rely On
Measured building surveys rely on accuracy, consistency and a clear understanding of how survey data will be used. Our surveyors combine technical knowledge with practical experience to produce drawings and models that are fit for purpose, whether required for design work, planning, compliance, or long-term asset management.
BIM-Ready Models for Coordinated Design
For projects requiring a higher level of detail, we produce Building Information Modelling (BIM)-ready survey data that forms a reliable foundation for coordinated design. Our models support clash detection, design integration and the development of the “golden thread” of building information increasingly expected for modern construction and refurbishment projects. By capturing accurate geometry and fabric information at the outset, we help reduce delays, improve coordination between disciplines and support long-term maintenance and asset management.

Accuracy Matters
Reliable design and refurbishment work begins with dependable measured data. Accurate surveys help prevent costly errors, design changes and delays further down the line.
Heritage Recording and Conservation Surveys
Historic and listed buildings require careful measurement and sensitive documentation. Our heritage surveys record the fabric, form and condition of traditional buildings to a level suitable for conservation planning, repair specifications and statutory submissions. We work in a manner respectful of original materials and construction methods, producing measured drawings that support informed decision-making without imposing unnecessary intervention. These surveys provide an accurate record for architects, conservation officers and owners, helping to guide maintenance, repair and long-term stewardship.

Reliable measured data is the foundation of effective design, compliance and long-term building management.
Area Measurement & Fire Safety Plans
Accurate measured areas are essential for a range of professional purposes, including rental assessments, valuation work, space planning and compliance with industry measurement standards. We produce precise Gross Internal Area (GIA), Net Internal Area (NIA) and IPMS-compliant figures, providing clear schedules that landlords, tenants and managing agents can rely on.
We also prepare fire safety plans to support building management and regulatory compliance. These plans identify escape routes, compartment lines and key safety equipment, offering a clear framework for day-to-day use and emergency planning. All drawings are produced from robust measured data to ensure dependable, site-specific documentation.

Congratulations to Sadie on Completing Her First Sale
Sadie Tyson, our recently qualified Sales and Lettings Agent, has successfully overseen the sale of a detached home in Brackley, handling the process with professionalism from start to finish.
Why Insurance Reinstatement Cost Assessments Matter
Reinstatement Cost Assessments (RCAs) are essential to ensure properties are correctly insured in the event of significant damage or loss. During a recent visit to the historic Raynsford Almshouses in Northampton, we assessed the rebuilding costs of this 17th-century Grade II listed property. Proper valuations help avoid the risks of underinsurance or overinsurance, ensuring these important buildings remain protected for the future.
