Londoners have long since been creative with their property. But only in the past couple of decades have residents begun to create new property from the space in between traditional residential plots. The release of brownfield sites, redundancy of old industrial property and partitioning of gardens has freed up untold square metres for development, from a fraction of an acre in a south London rear laneway to a multi-acre parcel of land north of the centre.

London’s new “right to build” homes scheme – born, in part, to help relieve the city’s housing shortage – requires local councils to keep registers of land suitable for self-builders, and to green-light more proposals to develop that land. It also asks developers to allocate fractions of their land purchases for local self-builders. This means new opportunities for imagining new ways of living in the city and beyond – at a lower price than you’d imagine. Today self-builders account for nearly 10 per cent of private self-build homes in the UK.

To build a house in London and beyond requires a trusted architect, a commitment of time and a budget of upwards of £2,000 per square metre. This money will cover not only a bespoke living space with all of today’s modern conveniences, but all the troubleshooting that arises when building in an open space, like planning permissions, insurance, party-wall issues, awkward access, sustainability requirements, expert consultations and financing (it can be tricky and time-consuming to secure a mortgage for a self-build home).

That said, many self-build homes are exempt from community infrastructure levies, VAT and the high stamp duties calculated for existing homes. And some of the build costs of building anew could pan out to be blessings in disguise – having control over the environmental standards of a home, for instance, can create an eco-friendly home that will reduce your cost of living for years to come. Self-builders are generally believed to spend 20 per cent less on land and build costs than other home-buyers, for a more individual result.

Consulting an architect in an effort to build a house in London and beyond the city will not only ensure a tailored, functional living space but could also reduce the need for expensive furnishings that deteriorate over time. An architect familiar with your needs will build in banquettes, platforms, kitchen installations, storage and wardrobes that will accommodate a growing family. Within about two years of finding the ideal land on which to build homes, you could be moving into the house you’ve always envisioned for yourself.

Build a House Do you pay VAT on a self build house?

Anyone choosing to build a house is exempt from paying most VAT. This came into place to ensure the rules were fair for those building a home as well as for those buying a newly built home.

Self builders can claim back much of the VAT on their build, although not everything is an expense that you are able to claim on. You can find out the rules in VAT notice 431NB, “VAT refunds for ‘do-it-yourself’ builders and converters”, which you can get from HMRC. It applies to people building their own home or converting a property to a residential property, but not developers.

If you want to make a claim to get some of your VAT back, you need to do so within three months of completing the build. You have one opportunity to make a claim, so ensuring you get it right is essential.

VAT-registered builders and contractors should not charge VAT on labour-only or supply and fix contracts. Self builders have to pay VAT on the materials they buy, and they can later claim much of it back. Some examples of what you can claim for interiors include fitted kitchen units, wood flooring and paint, whereas freestanding kitchen units or carpets would not be allowed.

You can make a claim for VAT on your self build house by filling in HMRC form 431NB for a new build or 431NC for a conversion. It’s important to keep a list of expenses and invoices as evidence.

Build a House >>Scenario Architecture In our clients words


We wanted to renovate our house in a conservation area in central London. Given this involved a complete demolition and new build with an extra floor on top, getting planning approval was always going to be tricky. Scenario did an amazing job on the new house ‘envelope’ and throughout the planning applications phase. We couldn’t have wished for better from them and having succeeded in gaining planning approval owe them a very big ‘thank you’.


Scenario designed a kitchen extension for us, and we are delighted with the results. The build process was well organised, planned and delivered, and the whole team were a pleasure to work with. I would highly recommend them for their design, planning applications and project management skills.


Worked with these guys on the internal development of our office. From start to finish they were great. They got what we wanted first time and really made working with them very easy. Their aftercare has been great too helping us deal with something that they were not involved with in the first place. Will highly recommend them to anyone.
