For a lot of self-builders, the hunt for an appropriate constructing plot represents one of many greatest challenges of your complete venture. But, current modifications to nationwide planning coverage might unlock new potential avenues for monitoring down land; particularly, alterations made to the coverage round brownfield websites.
In 2024, the federal government pledged its help for the event of brownfield land – that’s, land that’s beforehand been developed for an additional, often industrial, goal. It additionally launched £68 million’s value of funding to pick native authorities to assist clear empty buildings, former carparks and industrial land for home constructing, together with self and customized construct.
However, constructing on brownfield land is not with out its dangers. We share knowledgeable suggestions for a profitable final result.
What are some great benefits of constructing on brownfield land?
If very important infrastructure and repair connections exist already on a brownfield web site, it might make the plot a gorgeous prospect for would-be self builders.
“Brownfield plots virtually at all times have current connections to providers similar to electrical energy, water and sewerage, together with good-quality entry that saves some substantial preliminary prices,” says Robert Elkins, architect and artistic director at Artel31.
From a planning perspective, there might be additional advantages to self constructing on land that’s already been developed. “It’s extra prone to be zoned by the native planning authority as appropriate for improvement,” says Matt Loader, director at Loader Monteith. “If this isn’t the case, an argument can be made that improvement needs to be supported as a result of historic precedent.”
Plus, in case you’re seeking to develop land that’s presently house to a run-down, ugly eyesore, you possibly can argue that erecting a gorgeous, bespoke house as an alternative will profit folks dwelling and dealing within the surrounding space, too.

1. Discover all avenues to discover a plot
Most of the conventional avenues for discovering a plot to self-build on apply to brownfield plots too, as Spencer Man, an architect at Levitate Architects who designed and constructed his own residence on a brownfield plot in Buckinghamshire confirms.
“Our brownfield web site had been promoted by the earlier proprietor who obtained planning consent for a brand new dwelling. We noticed the gross sales particulars on a web site discovering web site,” he says.
“These varieties of internet sites are nonetheless the best method of discovering land, and more and more landowners are promoting their land by property brokers,” says Spencer. “Most worth might be achieved by looking for websites on Google or by travelling round, discovering and approaching the homeowners.”
However, whereas websites similar to Plotfinder and likewise auctions could also be a great place to hunt out brownfield plots, Robert and Hannah Elkins took a extra speculative method to discovering the proper plot, displaying that in some circumstances strolling round your required neighbourhood to establish websites with improvement potential is one of the best ways ahead.
“We knew the realm we hoped to stay in and the way restricted our choices can be, so we had been open-minded and artistic,” says Hannah. “We knocked on doorways and dropped letters by letter bins explaining that we understood the challenges and can be keen to supply with no survey.”
Rob and Hannah’s home, constructed on a former brownfield plot in Bristol, is the results of their efforts. The positioning was beforehand house to a industrial storage that had fallen into disrepair 20 years earlier than they purchased it.

2. Concentrate on the potential challenges
Simply as a brownfield plot could include the potential benefits of pre-existing infrastructure and providers, there could also be further hurdles to contemplate earlier than you construct.
Brownfield websites are sometimes tougher to construct on due to the elevated contamination danger. There’s a protracted checklist of doubtless hazardous substances to look out for, together with sulphuric acid for land beforehand linked with the oil business, hydrocarbons from gasoline storage and lead from metal works factories.
In the event you’re shopping for a web site that accommodates a disused petrol station, as an illustration, it’s doubtless the land is polluted with benzene and different petrochemicals that would pose a danger to the well being of future occupants.
“The danger of long-term detrimental results to your individual or your loved ones’s well being typically dissuades folks from starting the method,’ says Robert Elkins. “However, they will simply be managed supplied they’re factored into the early design levels.”
3. Fee the proper surveys
When constructing on brownfield land, “surveys needs to be undertaken to examine what’s current on the land,” says Spencer Man. “The opposite problem might be the removing of redundant buildings on the land, which frequently is harmful as they might comprise hazardous supplies,” he provides.
“We skilled each of those challenges when constructing on brownfield land and so they can just about at all times be overcome – however they typically value more cash than is anticipated on the outset,” warns Spencer.
When setting out your funds for constructing on a brownfield plot, it’s due to this fact necessary to have a beneficiant fund put aside to conduct the related surveys and cope with any potential points that come up in consequence.
When Robert and Hannah Elkins constructed their house, they had been most involved about the price of disposing of polluted soil if it was found throughout the excavation of their basement.
“Constructing under floor meant we would wish to take about 1,000 tonnes out of the positioning, so we explored the prices of doing so within the case of that occuring, and saved it as a contingency,” says Hannah. “We knew there’d be dangers and challenges, however the location was so necessary it was value it.”
4. Perceive what’s concerned when pulling down current buildings
If the brownfield web site you’re desirous about has current buildings on it, then your venture will most definitely embody the partial or a full demolition of these buildings to make method in your new house.
Nonetheless, it’s value taking into account that pulling down outdated buildings comes with its personal set of challenges to pay attention to earlier than you convey within the wrecking ball.
For instance, if the pre-existing construction is in poor situation, the native council could wish to see proof of your technique to hold passers-by secure earlier than you start demolition works. You’ll additionally have to assess whether or not there could also be any further hazards associated to the demolition, similar to asbestos.
A specialist survey might be required to establish the extent of danger and any measures that must be taken to maintain everybody on web site secure all through the development course of.
5. Allocate enough funds
Based on Derek Dawson from Scandia Hus, it might value extra to develop brownfield websites as a result of potential contamination points and demolition prices that is perhaps concerned.
“I might counsel that surveys are undertaken at an early stage to totally perceive the potential prices concerned from contamination points and demolition necessities,” he says.
Having stated that, these further prices to construct a home is perhaps balanced out by the financial savings you make on account of pre-existing providers connections and entry to the plot.
6. Be thorough with the planning course of
In concept, acquiring planning permission might be extra simple to realize on land that’s already been constructed on – on this case, brownfield land – than land that’s beforehand undeveloped.
Nonetheless, that doesn’t imply you possibly can skip the same old due diligence that’s required in the case of testing the native authority’s planning insurance policies and the planning historical past of the positioning you’re desirous about.
“Prior bidding on a brownfield web site is value and the native authority designation of the plot in query,” says Matt Loader. “If potential, make a bid on the land that’s topic to attaining planning permission.”
7. Think about your design rigorously
In the case of designing your individual self construct house, there’s a plethora of design selections. In actuality, the fashion of your new house and its dimension will doubtless be dictated – no less than to some extent – by the distinctive options of the plot you’re constructing on.
“Most planning insurance policies will state a choice for brand spanking new improvement roughly equal in dimension and scale to the historic improvement on the positioning,” says Matt Loader. “In our expertise, this may be flexed inside a margin of error by close by precedent, too.”
