House Extension Construction Roadmap
1. Initial Consultation & Site Visit
We begin with a site visit to discuss your ideas, assess the existing property and understand how the extension will be used. This allows us to identify any constraints early on and provide clear, practical guidance tailored to your home and lifestyle.
2. Design, Budgeting & Planning
We work closely with you to refine the design, agree specifications and establish a clear budget from the outset. Where required, we also advise on planning permission and structural considerations to ensure the project progresses smoothly.
3. Pre-Construction & Logistics
Once approved, we create a realistic construction schedule and manage all logistics to prepare for the build. You will be introduced to your dedicated project manager, and we implement protective measures to minimise disruption and safeguard the rest of your home throughout the extension works.
4. The Build Phase
Construction is carried out with precision and care, ensuring the new extension integrates structurally and visually with your existing home. Our team maintains a well-organised site and keeps you informed as the build progresses.
5. Snagging & Quality Assurance
We carry out thorough inspections to ensure all works meet our quality standards and agreed specifications. Any final adjustments are completed promptly to deliver a high-quality, finished space.
6. Handover & Aftercare
Your completed extension is handed over ready for use, with all agreed works finished to a high standard. We remain available after completion to provide advice or support should you need it.
Quality and Satisfaction Guaranteed
Every house extension we build is delivered with a clear focus on structural integrity, weather protection and long-term performance. We ensure that new works are properly integrated with the existing building, paying close attention to foundations, load paths, junctions and insulation continuity so the extension performs as part of the home rather than an add-on.
Quality is controlled throughout the build, not just at completion. Structural stages, weatherproofing, insulation and finishing works are carefully checked to ensure they meet agreed specifications and current building standards. This structured approach helps prevent issues later on and ensures consistency across every stage of construction.
The result is a well-built extension that feels solid, comfortable and reliable in everyday use. By prioritising correct construction methods, durable materials and careful detailing, we deliver spaces that remain functional, efficient and visually coherent with the rest of the property for years to come.

Everything You Need to Know - FAQs
Answers to Your Most Common House Extension Questions. If you have any other questions, feel free to contact us.
Do house extensions require planning permission?
How long does a house extension take to build?
The build duration depends on the size, complexity and specification of the extension. A smaller extension may take a few months, while larger or more complex projects will naturally take longer. By planning carefully and managing the build efficiently, we aim to keep timelines realistic and minimise disruption, while ensuring quality and attention to detail are never compromised.
Will the extension match my existing home?
Yes. We take great care to ensure every extension integrates seamlessly with the existing property. This includes matching proportions, rooflines, materials and finishes where appropriate, as well as ensuring clean structural connections between old and new. Our goal is for the extension to feel like a natural part of the home rather than a later addition.
Can you manage the entire extension project?
Yes, we offer a fully managed, turnkey service. This means we oversee the full construction process from initial consultation through to final handover. Clients benefit from clear communication, coordinated trades and a single point of contact throughout the project, ensuring the build progresses smoothly and efficiently.
Is a house extension a good long-term investment?
A well-designed and well-built house extension can significantly improve both the functionality and value of your home. By creating additional living space tailored to your needs, an extension can enhance everyday comfort while also increasing the property’s appeal and long-term resale value. Quality construction and thoughtful design are key to achieving lasting benefits.
