How to Sell a House with Non-Standard Construction in the UK

How to Sell a House with Non-Standard Construction
Property Buyers Today Featured On White

Non-standard construction can make selling your house tricky.

I’ve bought dozens of non-standard properties across the UK. Each case taught me new ways to handle these unique challenges.

My background:

I’m Saif Derzi, founder of Property Buyers Today. Since 2015, I’ve bought homes that others won’t touch.

If your house isn’t made from brick or stone with a slate or tile roof, it’s called “non-standard construction”.

This includes homes made from wood frames, prefab materials, or steel frames. These types of houses are usually harder to sell and take more time to find a buyer.

In this article, you’ll learn every way to sell your non-standard property.

I’ll explain what the law says and how long it takes. Plus, smart tricks to get the best price.

Most importantly, you’ll avoid costly mistakes other homeowners made. These errors can cost you thousands of pounds.


Understanding Non-Standard Construction Properties in the UK

Non-standard houses can be much harder to sell.

I’ve worked with many people who didn’t know their house was different. They get shocked when buyers and banks start asking hard questions. But knowing what makes your house special helps you get ready.

Most UK houses are made from brick or stone.

But after World War 2, Britain needed houses quickly. Builders used new materials and ways to build homes faster. Today, about 1.5 million homes in the UK are non-standard.

Common non-standard houses include: 

  • Steel frame building 
  • Wood frame building 
  • Concrete panel building 
  • Clay building 
  • Thatched roofs

Banks often say no to loans for non-standard houses. This makes finding buyers much harder than normal houses.

Insurance can cost more for unusual building types.

If you need to sell your house fast and it’s non-standard, cash buyers understand these problems. They can buy houses without needing hard bank loans.


Types of Non-Standard Construction Houses

Non-standard construction houses are built in different ways from normal brick houses. These houses can be harder to sell and get loans for. 

Knowing about the different types helps you understand what problems you might have.

Steel-Framed Houses

Steel-framed houses have metal frames instead of brick walls.

British Iron and Steel Federation (BISF) houses were built after World War Two using steel frames. The steel can go rusty over time, which makes the whole house weak. Many insurance companies won’t cover these houses because of rust problems.

Getting a mortgage on steel-framed houses is very hard. Most banks think they are too risky.

Timber-Framed Properties

Timber-framed houses use wood as the main building material.

These houses can catch fire more easily than brick houses. Damp is also a big problem because wood rots when it gets wet. Insurance costs are often higher for timber-framed properties.

Banks like newer timber-framed houses with proper promises. Older ones are much harder to get loans for.

Precast Concrete Homes

Precast concrete houses are made from concrete panels put together.

PRC houses were built quickly after the war using concrete panels. The panels can crack and let water in over time. Some types have problems that make them unsafe.

Most banks won’t lend money on PRC houses. Fixing concrete panel houses costs lots of money and is very complicated.

In-Situ Concrete Constructions

In-situ concrete houses are made on-site rather than using panels.

Wimpey No-Fines houses use concrete poured without fine sand. This makes the concrete weaker and more likely to crack. These houses often don’t keep heat in well and can be cold and damp.

Some banks will think about these houses, but usually want detailed reports first.

Alternative Materials

Some houses use unusual building stuff like cob, thatch, or have flat roofs.

Cob houses are made from clay, sand, and straw mixed together. Thatched roofs look lovely but need replacing every 25-30 years. Flat roofs often leak and need looking after regularly.

Special insurance is often needed for unusual building materials. This costs more than normal house insurance.

Modular and Prefabricated Homes

Modular houses are built in bits in factories, then put together on-site.

Post-war prefabs were meant to be temporary, but some still exist today. Many have problems and don’t keep heat in well. Modern prefabs are of much better quality, but some banks still won’t give loans for them.

If your non-standard construction house has become hard to live in safely, specialist buyers might be your best choice.


Challenges When Selling Non-Standard Construction Properties

Selling a non-standard construction house has lots of extra problems. These houses are much harder to sell than normal brick houses. 

Knowing about these problems helps you get ready.

Limited Buyer Pool and Market Perception Issues

Most buyers don’t want non-standard construction houses.

Normal homebuyers get scared by unusual building methods. They worry about hidden problems and expensive fixes. Many people don’t understand how these houses are built.

Cash buyers are often your best choice. They can buy without needing a bank loan. Finding the right buyer takes much longer than normal house sales.

Mortgage Availability Restrictions and Lender Concerns

Banks don’t like giving loans for non-standard construction houses.

Most banks won’t give loans on these houses. They think they are too risky. Even small unusual things can make a property hard to get a loan for.

Some special lenders will think about non-standard houses. But they want more money up front and charge higher interest.

Higher Insurance Premiums and Coverage Difficulties

Insurance for non-standard houses costs much more than normal.

Many insurance companies won’t cover unusual building types at all. The ones that will often charge double or triple the normal price. Getting quotes can be very hard.

Higher insurance costs put off many buyers who can’t afford the ongoing costs.

Valuation Complexities and Potential Price Impacts

Working out how much non-standard houses are worth is very hard.

There aren’t many similar house sales to compare with. Estate agents find it hard to price these houses. Non-standard houses often sell for 10% to 30% less than similar normal houses.

Getting accurate valuations takes longer and costs more money.

Longer Selling Timeframes Compared to Standard Properties

Non-standard houses take much longer to sell.

Normal houses might sell in 6 to 12 weeks. Non-standard houses often take 6 months to 2 years to find the right buyer. The legal process also takes longer.

You need to be patient and ready for a long selling process.

Legal Documentation Requirements and Surveys Needed

Selling non-standard houses needs lots of extra paperwork.

Engineer reports are often needed to show that the house is safe. Special surveys cost much more than normal house surveys.

All this extra paperwork costs more money and takes extra time.

Defective Designation Implications for Certain Property Types

Some non-standard houses are officially called defective.

The government has lists of problem building types that are known to be defective. Houses on these lists are almost impossible to get loans for. This makes them very hard to sell to normal buyers.

Check if your house type is on any defective lists before trying to sell.


Legal Requirements and Documentation for Non-Standard Property Sales

Non-standard houses need lots more paperwork than normal ones.

I’ve helped many sellers who got shocked by all the extra papers needed. Banks and buyers want to see that everything is safe. But getting the right papers ready early makes your sale go better.

Building checks make sure your house is safe. PRC papers prove that broken property types have been fixed.

Energy certificates work differently for non-standard materials.

Planning permission history shows all changes made to your house. Building regulation paperwork proves work was done right.

Insurance papers must show special coverage for your building type.

You must tell buyers what material your house is made from. This is the law, and you can’t hide it.

Local searches check what type of building your house is.

Key documents you need: 

  • Special surveys – safety checks
  • PRC certificates – repair proof for broken types
  • Energy certificates – for non-standard materials
  • Planning and building regulation papers
  • Special insurance documents

Getting all your papers ready to sell your house takes longer for non-standard houses. Start getting papers early to avoid delays.


Selling Options for Non-Standard Construction Houses

Estate Agents

The usual route is harder for different building types:

  • Average sale time: 9-15 months (takes longer – fewer people can get mortgages)
  • 1 in 2 sales fall through (more fail because banks say no)
  • You need agents who know your building type
  • You’ll pay these costs:
    • Agent fees (up to 3%)
    • Legal fees (up to £3,500)
    • Building checks and reports (£1,000-£3,000)
    • Safety papers or certificates (£500-£2,000)
    • Hard to market – not many buyers want them
    • Special mortgage fees for unusual lenders

    Property Auction 

    Selling at auction brings buyers who like unusual houses:

    • Timeline: 3-4 months
    • The sale happens right away when the hammer falls
    • Things to know:
      • House sold as-is – no mortgage problems
      • Brings rental investors and builders
      • Smart bidders know what unusual houses are worth
      • A bidding war can get good prices
      • Wait 4-8 weeks until auction day
      • Wait 28 days to finish the sale
      • Entry fees cost (up to £1,000)
      • Auction house takes (up to 6%)
    • Clear house details about the building type needed

    Improving Your Non-Standard Property’s Marketability

    Making your unusual house more appealing to buyers takes planning and work. The right changes can help you sell faster and for more money. Knowing what buyers want helps you focus on the most important changes.

    Professional Valuations and Realistic Pricing Strategies

    Get experts to tell you what your house is worth.

    Estate agents who know about unusual houses can give better advice. Don’t ask for too much money, or buyers will stay away. Being realistic about your house’s value helps it sell quicker.

    Renovation and Modernisation Opportunities

    Fixing and updating can solve many problems that put buyers off. Update old wires and pipes to make the house safer and nicer.

    New kitchens and bathrooms help buyers forget about the unusual building.

    Focus on changes that add real value to your house. Better fittings make your home feel more modern. Smart updates can increase your selling price a lot.

    Energy Efficiency Improvements and Insulation Upgrades

    Energy changes make your house cheaper to run.

    Better insulation keeps heat in and cuts energy bills. New windows and doors help with keeping heat in, too.

    Buyers like houses that won’t cost lots to heat and cool.

    Addressing Common Defects and Maintenance Issues

    Fixing common problems before selling shows buyers you care about the house. Fix any damp problems, cracks, or leaks right away.

    Get expert reports to show the house is safe.

    Dealing with problems early stops bigger issues during the sale. Small fixes now save thousands later. Buyers trust sellers who look after their houses properly.

    Obtaining Specialist Insurance Quotes and Mortgage Pre-approvals

    Get special insurance quotes before selling to help buyers understand ongoing costs.

    Some insurance companies work with unusual houses and offer better deals.

    Getting loan pre-approvals from special lenders shows buyers that financing is possible. This makes your house less risky for buyers.

    Professional Photography Highlighting Unique Features

    Professional photos can make your house look amazing in adverts. Good photographers know how to show unique features that make your house special.

    They can make an unusual building look interesting rather than scary.

    Great photos get more people to book visits. Online listings with poor photos get ignored. Professional images are worth the extra cost.

    Creating Comprehensive Property Information Packs

    Making detailed information packs saves time and builds buyer confidence.

    Include reports, insurance details, and any warranties. Put together information about the building type and its benefits.

    Having everything ready shows you’re organised and honest about your house.

    Market Timing Considerations and Seasonal Selling Patterns

    Market timing can make a big difference to how quickly you sell. Spring and early summer are usually the best times to put houses on the market. Fewer people look at houses in the winter months.

    Understanding when to sell your house can help you choose the right moment to start marketing.
