The Costs

 

Building And Renovation Costs

The prices below are based upon personal experience and a tabulation of different prices from the across the UK and also some works that we have done. It pretty much sums up how we price our works. There are no secrets with our pricing, when we quote we tell you exactly what the costs are and for what. But remember these are guides and rough pricing rather than exact figures that you will pay. Variations can occur based on the circumstances we face on each individual property.

How much my extension will cost me?

This is the question most frequently asked by people looking at getting a house extension. To be honest at the start of a project it is impossible to quote building costs without working drawings and a list of materials, fittings and fixtures.

Building costs for house extensions or home renovations can vary considerably depending on a number of criteria:

Choice of building materials, fittings and fixtures – bathroom and kitchen tap fittings, tiles, window frames, heating & cooling, lighting
The extent of client involvement – does the client choose to perform any of the building works such as painting
Commencement and duration of the building works – does the project extend over the Christmas holiday break or during seasonal busy periods – this will add to any interest cost and/or rental costs if you need to move out
Seasonal building market conditions – the number of rain affected days – this will add to any interest cost and/or rental costs if you need to move out
Town planning delays – this can result in additional costs and potentially add months to your building project
Size and competence of the selected building firm or builder – the bigger the business the more overheads and, by necessity, will pass this cost on to you. Each builder will factor in a different profit margin.

Varying professional fees – architect, draftsperson, town planner, structural engineer, soil report, building surveyor, etc
Abnormal ground conditions requiring additional site costs – a sloping block and/or the need to dig deeper to reach solid ground and so concrete pours will vary
And finally, there is the point of location, location, location. For example, a House Extension in London may cost more than a House Extension in Manchester, only because the cost of building is greater in London than in the North West.

However, considering that planning permission and drawings from start to finish will usually wind up at about £1,500 give or take some, the prices below will give you the average costs for a house extension. The rest is up to you and your preferences in the refurbishment of the interior.
