Cost Estimate for 21 Flats in London

I need a cost estimate for a proposed development of 24 Flats
with a mixture of 1,2 and 3 Bed flats.

This project seeks estimations for the construction costs of a residential development located in London comprising twenty-one flats of varying configurations. Specifically, the proposed development will consist of a mixture of one, two and three bedroom flats aimed at the private rental market. Estimations are required for all major aspects of construction including but not limited to: preliminary works, substructure, superstructure, internal finishes, fittings and maintenance. The estimations must be data-driven and factor in current market rates for labour and materials. Project managers and quantity surveyors with proven experience estimating construction projects of a similar scale and scope within the M25 area are encouraged to apply. Applicants should demonstrate their ability to accurately account for all expected costs and contingencies from project inception to completion. The submission should include a thorough yet concise written rationale breaking down the estimations into logical phases and line items. Additionally, submissions may provide comparisons to recently completed similar projects to benchmark the estimations. The selected applicant will be expected to stand behind their estimations and be available to further discuss or refine aspects of the estimates as needed. Ultimately, this project aims to inform feasibility and budgeting decisions for the proposed development through reliable cost projections from a qualified professional well-versed in London's construction market.
