Take full control of your dream home with a building method that saves time and energy. SIPs provide exceptional thermal performance, fast on-site assembly, and long-term energy savings ideal for modern living
Speed, scalability, and consistency - SIPs are perfect for modular schemes. Panels arrive prefabricated for precision assembly, reducing build times and labour costs while meeting high-performance standards.
Transform old structures into warm, airtight homes with SIPs. Ideal for retrofitting or inserting into existing frames, they bring modern efficiency while preserving original character.
Need more space? SIPs make it quick and easy to build high-performance outbuildings with excellent insulation and a sleek finish—whether for work, wellness, or guests.
Deliver comfort all year round with SIPs. Perfect for rural settings, they offer quick builds with outstanding energy efficiency—great for letting or personal retreats.
Add space without the stress. SIP extensions are fast to install and match seamlessly with existing structures while boosting energy performance.
If you’re building sustainably or aiming for off-grid independence, SIPs offer low energy consumption, minimal waste, and compatibility with renewable systems.
SIPs are ideal for ultra-efficient living. Their airtight construction and high insulation values help meet Passivhaus standards, reducing your reliance on heating and cooling.
We supply and install SIP homes and panel kits across the UK, including Greater Manchester, Lancashire, Cheshire, Cumbria, Merseyside, and surrounding regions — delivering efficient homes on time and within budget.

McVeigh Offsite are specialists in SIP panels (Structural Insulated Panels) and SIP design & construction to create highly efficient building envelopes using the ‘Fabric First’ approach and sustainable designs.
Yes. Structural Insulated Panels combine insulation and structural strength, helping reduce heat loss through the walls and roof. Carefully sealed joints also help limit unwanted air leakage. The finished home’s energy performance depends on the complete design, including floors, windows, doors, ventilation and installation quality.
Once the foundations are ready, the SIP shell can be erected quickly because panels arrive cut and prepared for assembly. McVeigh’s typical guide is around two to three weeks from sole plates to a weather-tight shell, depending on the project and site conditions. Foundations, manufacturing lead times, services and internal finishes require additional time within the overall build programme.
Yes. SIPs can be designed and fabricated to suit individual house plans, including contemporary homes, traditional styles and open-plan layouts. Large openings and more complex designs may need additional structural support. Involving McVeigh early helps your architect coordinate the layout, structure and panel design before fabrication begins.
There is no single answer: costs depend on the house design, specification, site access and what the package includes. Compare complete build costs rather than panel prices alone, taking account of installation, insulation, labour and time on site. McVeigh can review your drawings and provide a project-specific quotation so you can make a fair comparison.
