Accurate Commercial Estimates from Qualified Quantity Surveyors
Commercial construction projects demand a level of detail and accuracy that goes beyond standard residential estimating. From office fit-outs and retail refurbishments to warehouse conversions and hospitality venues, every commercial project has unique cost drivers that require specialist knowledge to quantify correctly.
Our qualified Quantity Surveyors have extensive experience across every sector of the commercial construction market. We understand the complexities of Cat A and Cat B fit-out specifications, the cost implications of DDA compliance, landlord requirements and the phased handover schedules that commercial clients often need.
Whether you are a developer appraising a commercial opportunity, a contractor tendering for a fit-out, or a business owner planning premises improvements, our estimates give you the accurate cost data you need to make confident decisions.
