Below is a guide to calculate typical construction costs of various buildings per m2 of gross internal floor area (internal area of the building measured over internal walls and partitions, stairwell openings etc).
Unless stated otherwise, the costs are based on buildings constructed to a typical or mid-range specification. Building size and shape, number of storeys, ground conditions, design and material specification, number of lifts, local market conditions, etc. can all have a significant impact on costs.
It is quite possible for costs to vary from the range of guide costs given here.
The costs given here are intended only as an indicative guide and should be used with understanding.
We have used our Costmodelling CostAdviser software to produce cost models covering a large range of building types. Analysis of this information provides the following results:
All costs are set at current index 191 - 2Q2021 (Year 2000 = 100), at UK national average (index 100) and a building works value factor of 1. See the Construction Indices, the Regional Variations and the Project Value Adjustments pages for more details.
The costs below are for the building only (i.e. no external works), and are inclusive of preliminaries, and contractor's overheads and profit set at 7.5%.
Important! When using the information from the table below, it is important that any costs produced are adjusted using the project value adjustment factor obtained from the project value adjustment chart.
All the costs in the table below are set at a project value factor of 1. When you obtain a total building cost for your project by multiplying the gross internal floor area by the cost per m2, you should multiply the resultant total cost by the factor obtained from the chart that corresponds to your total. This will help ensure that your project costs reflect the economies of scale appropriate to your project size.
An example of how to use the information to create a construction works budget is provided at the end of this page.

If you wish to create a detailed cost model yourself, download our app. It's simple, easy to do, quick and completely free of charge! Go to our download section and use our wizard to create your cost model from scratch.
The following is an example of how an early cost advice budget may be put together when all that is know about the project is building size (gross floor area), location and an indicative start of construction date.
If you don't know any better, we would typically add a further 10 - 20% of the building cost to cover the costs of external works depending on how extensive these works are. External works include site preparation works, roads, paths and pavings, planting, fencing, railings and walls, site/street furniture and equipment, external drainage and external services.
We would typically add a figure of 10 - 15% to cover risk (contingencies).
Professional fees can be anything from 5% to 15% depending on the size of the project - generally the larger the project the smaller fee percentage.
Important! When using the information above it is important that any costs produced are adjusted for building works value. As stated, all the costs per m2 on this page are based on a building works value factor of 1 (building works value of approximately £1,000,000.
The cost per m2 given for a detached house for example is for a project in which the house is costing some £1,000,000 (i.e. a building works value factor of 1). If your house is only costing £250,000 the project value adjustment must be applied to produce the cost per m2 appropriate for your building value (in this example, the building works value factor would be 1.07 i.e. cost per m2 needs to be 7% more than the cost per m2 given in the table above.)
Making this adjustment will help produce costs that are relevant to your project size and value.
This example is for a proposed new office block in York, 2000m2 gross floor area, with a proposed construction start date of October 2021.
