How much does it cost to build a luxury house in London or Hertfordshire?

When estimating the cost of your new build project, you will have to consider several different factors. For new build luxury house in London or Hertfordshire, expect the minimum building cost to be somewhere between £1,750 and £4,000 per square metre. This will depend on the plot, size and type of the property, and design specifications. For example, how many floors will the new house have, does your proposed design include floor-to-ceiling glazing, are there any special planning considerations, is there an existing structure that has to be demolished, etc. All these questions and more should be answered when preparing your budget.
Cost of building a luxury new build home in London or Hertfordshire

When starting your estimation process, you could begin by looking at the items below:

  • Plot cost: The cost of the property site will vary mainly depending on the location and the size. A plot which has consent for the construction of a new property will cost more than a similar site without building approval. However, there is a significant risk involved when buying a plot without approval and applying for permission later. Sometimes, it might be cheaper to by an existing older property, demolish it and build a new house in its place.
  • Architectural design: Expect to pay up to £50,000 to have a complete set of drawings prepared by an experienced architect and structural engineer. As we work with some of the most skilled architects in London and Hertfordshire, we can offer architectural services at discounted rates if you opt for our design and build London services.
  • Superstructure: Traditional masonry (block and brick walls) tend to be more cost-effective since many London builders have more experience with their construction. Other, less common, forms of construction, such as cross-laminated timber are more likely to cost up to 15 per cent more.
  • Energy efficiency: New build construction is the perfect opportunity to create eco-friendly, highly insulated home, which will significantly reduce the energy bill. While it might be slightly more expensive to build an energy-efficient house, it will add value to the property and save money on your energy bills while offering many environmental benefits.
  • Glazing: large areas of glazing, such as floor to ceiling sliding glass doors, will cost more than standard masonry with more traditional doors and windows.
  • Kitchen fitting: A high-quality hand-painted kitchen can cost anything between £50,000 to £200,000.
  • VAT: There is no value added tax payable on the cost of building a genuine self-contained new house. However, there are a few items where VAT is always applicable, such as the architect's and consultant's fees.

Can you build a luxury house for profit?

Luxury new build house in Hertfordshire

In London and Hertfordshire, the land is scarce, and plots with building approval will come with high premiums. The cost of purchasing the land might even exceed that of the actual house construction. Whilst it is still possible to profit from building a luxury property, the markup will not be very high.

Often, one of the main reasons for building a luxury new house is to create a bespoke home tailored to individual tastes and requirements.

COVID-19 and new home construction

Just with everything else, coronavirus has caused significant disruption to the construction of new build homes.

However, if you have only started planning your new house, you will first need to find an architect who will prepare and submit the drawings which will take several months.

By that time, the restrictions should be lifted, and your chosen luxury new home builders can commence the construction, so there is no reason why you should put your plans on hold.
