Mortgages for a factory-made shell
BOPAS accreditation is what makes a modular home mortgageable. It is the scheme lenders, valuers and warranty providers look to for independent evidence that an offsite-built house will still be performing in sixty years.
BOPAS accreditation and certificates →If the build grows beyond what you want to manage, the same shell is available as Shell + Assembly or Turnkey base; see the price guide for both.
Common questions
Do I need to prepare a foundation before you deliver?
Yes. Foundations are required before delivery. For Base contracts, the client is responsible for groundworks. For Turnkey contracts, we can include foundation and groundworks within the scope. This is typically discussed at the quotation stage.
Can I add services to a Base contract separately?
Yes. We can provide individual services such as electrical installation, plumbing or internal joinery as separately priced additions to a Base contract. Speak to us at quotation stage.
Can I adapt a standard design to suit my site?
Yes. Most of our standard models can be modified in size, layout, external finish and internal specification. We review your site and plot constraints before recommending the most suitable approach.
Do residential homes require full planning permission?
Yes. However, we can provide planning support and work with your architect or planning consultant if required.
Is finance available?
We do not arrange finance directly, but can recommend specialist providers for self-build and garden room finance.
