Our Services
Extension & Conversion
For extensions or loft conversions, precise structural calculations and detailed technical drawings are essential to obtain Building Control approval. At Laytoe Structures, we specialise in designing foundations, beams, lintels, and all aspects of structural alterations. Our team of qualified and chartered structural engineers ensures every project meets the highest standards.
We work closely with clients and their design professionals to deliver cost-effective and practical design solutions.
Mortgage Structural Survey
If a lender’s valuer flags structural concerns with a property you’re looking to buy, Laytoe Structures' chartered engineers are here to help. Our MICE or MIStructE qualified experts will assess the issues to ensure the property is safe and your investment is protected.
We work with all major lenders, including Barclays, Santander, and Nationwide. Over the last eight years, we’ve helped hundreds of clients secure their mortgages.
Structural Reports for Insurance Purposes
If your property has a history of subsidence and you’re facing higher premiums from your current insurance provider, it might be time to explore other options. Many insurers are willing to offer lower premiums, provided you have a structural report confirming that your property is safe to insure.
At Laytoe Structures, our team of experienced engineers is ready to provide a tailored structural survey report for this specific situation. Over the past eight years, we have assisted hundreds of clients in switching their insurance providers, helping them save thousands of pounds.
Structural Surveys for Homebuyers
Structural Inspection
Your surveyor has flagged movement, or you've found a crack you can't explain, and you need to know before you exchange. Our engineers inspect the property and tell you plainly whether it's cosmetic or structural, what it will cost to put right, and whether you have grounds to renegotiate.
General Structural Inspection (GSI)
A General Structural Inspection (GSI) involves a thorough evaluation of a property's overall condition through visual inspections. This includes identifying severe cracks, subsidence, and movements, as well as assessing the impact of nearby trees and shrubs on foundations per NHBC guidelines.
COMPREHENSIVE GENERAL STRUCTURAL INSPECTION (CGSI)
In addition to the areas inspected in a GSI, this inspection includes a visual assessment of the roof structures, cellar, and outbuildings. A CGSI does not limit the number of cracks inspected, and we will also visually evaluate all internal alterations and report on any previous alterations to the property’s structures.
Specific Structural Inspection (SSI)
A Specific Structural Inspection (SSI) focuses on investigating a single structural issue or crack within a property. Unlike a GSI, an SSI is limited to one specific area, providing a targeted examination of a particular concern. This type of inspection addresses localised problems.

If you are a leaseholder planning to remove a wall or make internal alterations to your property, you will typically need consent from your freeholder or property management. This approval ensures that the integrity of the property remains uncompromised.
At Laytoe Structures, we can assist by providing detailed reports for wall removal and other alterations. Our reports address the concerns of your freeholder, helping you achieve your desired layout with confidence and ease.

Crack Monitoring
Structural cracks and movement can be caused by a range of factors, including shrinkable clay soils, nearby trees and vegetation, leaking or defective drainage, changes in ground moisture, and foundation movement. These issues can lead to subsidence, settlement, and other forms of structural movement, often becoming visible through cracks in walls, ceilings, floors, or around windows and doors.
At Laytoe Structures, we provide professional subsidence inspections, structural inspections, and crack monitoring services in London to help determine whether structural movement is ongoing or historic.
