The Story

From Poland to the UK, building the right way.

I started in construction in Poland, where the craft was taken seriously and attention to detail was expected — not optional. I learned from experienced tradespeople who understood that a building's long-term performance depends entirely on the quality of decisions made during construction.

I worked in Germany, where precision engineering meets construction — an environment that shaped my approach to airtightness, thermal bridge elimination and the kind of detailing that actually makes the difference between a good passive house and a great one.

Mallorca taught me a different kind of rigour: luxury residential work in a climate where thermal comfort, material quality and client expectations left no room for compromise.

Bespoke hand-carved fretwork balustrade, backlit by concealed LED — every project starts with the same standard of detail.

From 2013 I worked as an independent contractor across the UK — taking on increasingly complex residential refurbishment and construction projects, building deep expertise in building physics, fabric performance and energy-efficient detailing along the way. Over those years a pattern became clear: clients were being let down not by lack of ambition, but by builders who didn't understand the standard, consultants who didn't build, and supply chains that didn't deliver performance. The gap between what low-energy construction could achieve and what was actually being delivered was significant — and avoidable.

Consolidated at source in Poland — pallets of insulation, sanitaryware and adhesives for a single APMBuild UK delivery.

I established APMBuild Ltd in 2024 to close that gap properly. Not as a volume contractor, but as a quality-first specialist — combining PHI-accredited Passive House training, a direct European materials supply chain, and personal site oversight under one roof.

"I am not running a faceless building company. I oversee every project personally. When you call APMBuild, you speak to me."

Credentials & Expertise

What I bring to your project.

Qualification

Level 2 — Passive & Energy-Efficient Construction

Completed PHI-accredited Level 2 Master Passive House construction training at Akademia Zdrowego Budownictwa (AZB), a Passive House Institute-accredited training body, Wrocław, Poland (2023). Working knowledge of PHPP methodology, airtightness detailing, thermal bridge principles, and EnerPHit retrofit strategy.

Experience

20+ Years — Poland, Germany, Mallorca, UK

From high-precision German construction to luxury Mediterranean residential. A breadth of experience that most UK contractors simply don't have.

Supply Chain

Direct European Supply Chain

Established relationships with CE/UKCA certified European manufacturers. Materials typically 20–30% below UK market pricing, with 5–10 day typical delivery.

The Team & Recent Work

Direct accountability. Real projects.

Paweł Okurowski

Director & Founder

Project oversight, PHPP pre-assessments, client contact, European supply chain. Single point of accountability from first call to final handover.

Recent Project

External Works & Landscape

Composite decking, stainless cable balustrades, structural retaining works and lighting integration. Private residence, Herefordshire.

Recent Project

Garden Stair & Terrace

Multi-level deck, slate-clad piers and stainless balustrade detailing. Built to outlast typical timber installations through material specification.

How PHPP Works

The PHPP Assessment Process

Every APMBuild project starts with a PHPP pre-assessment — the energy modelling tool developed by the Passive House Institute. Here is how it works, from first data to certified result.

PHPP — Passive House Planning Package PHI Standard STEP 1 Property Data · Floor area & form factor · Orientation & location · Current EPC / fabric STEP 2 Climate Data Set · UK weather station · Solar radiation data · Design temperature STEP 3 Building Fabric · U-values (wall, roof, floor) · Window spec & Uw · Thermal bridges (ψ) STEP 4 Building Services · MVHR efficiency ≥75% · Airtightness n₅₀ ≤1.0 · Heat pump / heating PHPP ENERGY BALANCE CALCULATION ≤25 kWh/m².a Heating Demand ≤1.0 ACH @ 50Pa Airtightness ≤60 kWh/m².a PER Primary Energy ✓ EnerPHit Certified All criteria met → Certifier issues certification plaque ↺ Optimise & Iterate Adjust fabric spec / services / orientation → re-run PHPP EnerPHit TARGETS (UK) Heat demand ≤25 kWh/m².a Airtightness n₅₀ ≤1.0 ACH PER ≤60 kWh/m².a PHI criteria Version 10c (valid from April 2023) · Paweł Okurowski — PHI-accredited Level 2 Passive House construction training (AZB, 2023)

How We Work

Four things that don't change.

No shortcuts

Low-energy building performance depends on doing every detail correctly. We don't cut corners on airtightness, thermal bridges or specification.

Transparent pricing

You get a clear cost breakdown before any work starts. European materials pricing is passed on honestly — we don't inflate margins on supply.

Honest timelines

We give realistic programmes, not optimistic ones. If something changes, you hear it from Paweł directly, not from a project manager who wasn't there.

Craft over volume

We work on a small number of projects at a time. Quality requires attention, and attention requires limits. We'd rather do fewer projects properly.
