Property advice that actually helps
Researched, UK-specific guides for every stage of homeownership — from buying and surveys to retrofit, planning and major works.
Planning & Pre-BuildThin-Shell Concrete Residential Architecture and Design in the UK
Thin-shell concrete construction uses curved or folded concrete forms — including domes, vaults, and hyperbolic paraboloids — to achieve structural efficiency through shape rather than mass. In UK residential projects, these structures require specialist architectural and structural engineering input from the outset, and will almost always require full planning permission, with pre-application discussions strongly advisable.
Planning & Pre-BuildArchitectural Design Services for Home Extensions and Renovations
Architectural design services for UK extensions and renovations span initial feasibility, planning drawings, building regulations packages, and site monitoring. The right professional depends on your project's complexity: a chartered architect suits sensitive or complex work, while an architectural technologist handles most standard extensions competently and at lower cost.
Planning & Pre-BuildEffective Site Management: Best Practices for Building Project Success
Effective site management on a UK building project requires a clear programme, written contracts, CDM Regulations compliance, and proactive coordination between the principal contractor and all trades. For projects involving more than one contractor, a Principal Designer and Principal Contractor must be formally appointed. Regular building control inspections at key hold points and a 10–15% contingency budget are central to project success.
Planning & Pre-BuildBuilding Concrete Homes with Foam Forms: Alternative Construction
Insulated concrete formwork (ICF) uses lightweight EPS foam blocks as permanent shuttering filled with reinforced concrete to form walls. The foam stays in place as insulation on both wall faces. ICF homes can achieve U-values well below Part L minimums. Building regulations approval, a chartered structural engineer, and a BBA-certified ICF system are required for any UK new build or extension.
Planning & Pre-BuildDesigning and Building a House: Architectural and Engineering Guidance
Building a new house in the UK requires separate planning permission and Building Regulations approval, a professional team typically including an ARB-registered architect, a structural engineer, and often a civil or geotechnical engineer. A topographic survey and ground investigation should precede detailed structural design. The process typically spans 12 to 24 months from initial design to a building control completion certificate.
Planning & Pre-BuildUnderstanding building foundations: what homeowners need to know
Building foundations transfer a structure's load safely to the ground beneath it. In the UK, the most common type is a strip foundation — a continuous concrete strip under load-bearing walls, typically at least 1 metre deep in clay soils. Foundation design must comply with Approved Document A and receive Building Control approval. Complex or high-risk sites usually require a geotechnical ground investigation first.
Planning & Pre-BuildHeritage Property: Preserving Historic Homes and Conservation Standards
Listed buildings in the UK require Listed Building Consent for most works — internal and external — that affect their special architectural or historic interest. Conservation area properties face additional restrictions on permitted development. Carrying out unauthorised works is a criminal offence. Always consult a heritage consultant or your LPA's conservation officer before starting any works on a historic property.
Planning & Pre-BuildSubsidence Remediation and Foundation Repair Costs
Subsidence remediation in the UK typically costs £5,000–£50,000+ depending on cause and method. Traditional underpinning runs £1,500–£3,000 per bay; resin injection often costs £10,000–£25,000. Most claims go through buildings insurance. A structural engineer must confirm the cause before any remediation method is specified.
Planning & Pre-BuildPlanning and Building a House Extension: Step-by-Step Guide
A house extension in the UK usually requires either planning permission or confirmation of permitted development rights, Building Regulations approval, and — where work affects a shared wall or boundary — compliance with the Party Wall etc. Act 1996. Most single-storey rear extensions are permitted development, but two-storey, side, and large rear extensions typically need a full planning application.
Planning & Pre-BuildBay Window Foundations: Structural Design and Support Requirements
Bay window foundations must transfer the bay's structural load to the ground independently of the main wall. In older UK homes, shallow brick piers on rubble footings often fail on shrinkable clay soils. A structural engineer should specify the foundation type for any new or failing bay, and Building Regulations Part A approval is usually required.
Planning & Pre-BuildNew Build Foundation Costs and Construction
In the UK, new build foundation costs typically range from £5,000 to £30,000 or more, depending on foundation type, site conditions, ground investigation findings, and build size. Strip foundations suit stable ground; raft or pile foundations are needed where ground conditions are poor or structural loads are higher.
Planning & Pre-BuildStructural Wall Removal: Safety Considerations and Professional Requirements
Removing a load-bearing wall in the UK always requires Building Regulations approval under Approved Document A, plus a structural engineer's beam calculation before any demolition begins. Building control must inspect and sign off the beam installation before it is concealed. Properties built before 2000 also need an asbestos survey completed before any breaking out starts.
