Passive House-Trained Contractor for Architects & Developers We build what you design.
On spec. On time.
A Passive House-trained contractor who understands the spec, won't substitute products, and won't need explaining to about q50 and ψ-values. European materials with full CE/UKCA documentation.
A contractor who speaks your language.
APMBuild works as your build partner on architect-led energy-efficient projects, EnerPHit retrofits and Passive House-informed new builds. We read PHPP outputs, understand thermal bridge details, airtightness strategy and the documentation requirements that come with PHI-aware schemes — delivering your design rather than re-doing it. Your client, your scheme, your drawings.
We deliver PHPP-informed pre-assessments directly. Full certified PHPP models are delivered through our PHI-accredited partner. If you need a build partner who will deliver your designed performance — not approximate it — that is what we do.
Build execution to high-performance specification — airtightness, thermal bridge mitigation, MVHR commissioning coordination.
European materials supply UK-wide — CE/UKCA compliant, full technical documentation; stock items typically delivered in 5–10 days, made-to-order windows and doors typically 4–8 weeks. See full range →
PM & site coordination available — oversee your existing contractor team to high-performance standard. Details →
On-site practical mentoring for build teams — airtightness, EWI, MVHR, thermal bridge details delivered on your site. UK-wide. Details →
European materials. High-performance specification. Better margins.
Our direct European supply chain delivers high-performance specification materials often below UK-equivalent pricing — without compromising on quality or compliance. Every product is CE/UKCA marked with full documentation.
Beyond the energy-efficient fabric range, our supply chain also covers structural, finishing, kitchens, bathrooms and bespoke furniture — a full house package from a single source. See full materials range →
We help model the build cost and the predicted energy performance from the outset, so you understand the numbers before you commit.
CE/UKCA certified. Stock items typically in 5–10 days. Full documentation.
Every materials order comes with U-value calculations, technical data sheets and full compliance documentation — ready for your building control submission.

Architect and developer questions
How APMBuild collaborates with design teams and multi-unit schemes.
How does APMBuild collaborate with architects?
APMBuild works alongside architects as a Passive House-trained main contractor, providing buildability input, PHPP pre-assessment, material specification and detailed delivery. Paweł Okurowski's PHPP training and 20+ years of European construction experience means we engage early on detailing rather than just executing drawings.
Can you do PM-only or tender-only engagement?
Yes. APMBuild offers project management-only, construction management, tender packages or full design-build A–Z engagement depending on what the architect or client needs.
Do you provide PHPP modelling for our designs?
Yes. APMBuild carries out PHPP pre-assessments directly, covering U-value calculations, thermal bridge analysis, MVHR sizing and overheating risk checks. Full certified PHPP models are delivered through our PHI-accredited modelling partner. Either can be commissioned standalone or bundled into delivery.
Can architects open a trade account for materials?
Yes. Architects, developers and specifiers can open a trade account with APMBuild to access CE/UKCA-compliant European insulation, windows, MVHR units, airtightness products and doors. Stock items are typically delivered UK-wide within 5–10 days; made-to-order windows and doors typically take 4–8 weeks.
What documentation do you provide?
APMBuild delivers full technical documentation: PHPP reports, U-value calculations, product datasheets (CE/UKCA), airtightness test results, MVHR commissioning records, the contractor records a Retrofit Coordinator needs where PAS 2035 applies, and as-built drawings. All documentation is handed over digitally on project completion.
Do you work on multi-unit developer schemes?
We are open to them, and we will be straight about where we stand: APMBuild has not yet delivered a multi-unit scheme, so these are discussed case by case rather than on a track record. Schemes from three units upward, where energy performance is central to the value proposition, with joint venture as one possible route.
