BuildFast Hull Limited operates as a principal building contractor across Hull and East Yorkshire, delivering residential extensions, new-build properties, and structural construction projects for homeowners, developers, and commercial clients. Our team manages groundwork, brickwork, structural steelwork, roofing, and first-fix joinery giving you one contractor accountable for the full build rather than a chain of separate subcontractors.
A well-designed extension adds space and value without the cost and disruption of moving. We carry out single-storey rear and side extensions, double-storey extensions, wraparound extensions, and garage conversions across all Hull postcodes. Every extension project includes full groundwork, blockwork construction, roofing, windows, and internal finish to building regulations standard.
What’s included:
We undertake new residential build projects in Hull and the East Riding. From single plots to small residential developments. Our experience covers traditional brick-and-block construction, timber-frame builds, and mixed construction methods. We can work from architect-drawn plans or coordinate the full design-and-build process on your behalf.
From RSJ beam installations to complete structural alterations, our team carries out all types of structural construction work, party wall work, chimney breast removal, load-bearing wall alterations, underpinning, and foundation repairs. All structural work is carried out in line with current Building Regulations and coordinated with a structural engineer where required.

Yes, we regularly work from architect-drawn plans. We can also recommend architects and structural engineers in Hull who we work with regularly if you need design assistance.
