AHKO approach

This is not project management.
It is complete dedication — to the building, and to the standard it deserves.

A SPECIALIST READING OF THE BUILDING

Property Health Check

Historic buildings are rarely what they first appear. Beneath the architectural character lies a history that only an experienced eye can read.

The Property Health Check is a specialist visual assessment of a historic or period property, carried out in person by Adam Harasimowicz. It tells you what the building truly is — its original fabric, its condition, the works it requires, and what those works are likely to cost.

When to commission one:
• Before purchase — understand what you are really committing to before you sign.
• Before sale — understand the issues a buyer’s surveyor may raise before they become negotiation points.
• Before renovation or extension — understand the building before appointing architects or builders.
• For existing owners — a clear view of condition, risks and repair priorities.

Delivered as a professional written report within five working days. Carried out personally by Adam Harasimowicz. Available for period houses, flats and apartments across London and Surrey.

CLIENT ADVOCACY & PROJECT OVERSIGHT

Client Representation

Historic buildings deserve informed oversight. AHKO acts solely in the client’s interest — helping owners navigate complex decisions, appoint the right specialists, and protect both the building and the investment it represents.

Through independent guidance, specialist coordination, and direct project oversight, AHKO provides clarity, accountability, and continuity from first instruction to final completion.

Available for:
• Property owners undertaking renovation, conservation or refurbishment works.
• Historic properties across London and Surrey.

TRUSTED SPECIALIST NETWORK

The Circle

Over 25 years of working on historic buildings, AHKO has built relationships with a small number of exceptional specialists — architects, engineers, and craftsmen — each known through direct professional experience, each trusted to work on buildings that were built to last, and deserve to be treated accordingly.

The Circle is not a directory. Every member has been chosen by Adam personally — because they have been seen at work, on buildings like yours, and found to be exceptional at what they do. Enquiries come directly to AHKO. The introduction that follows reflects 25 years of professional judgment.

Available to:
• Private clients, architects, heritage consultants and estate managers.
• Working across historic properties in London and Surrey.

ABOUT AHKO

AHKO provides Property Health Checks, Client Representation and access to The Circle for owners of historic buildings across London and Surrey.

Founded in 2006 and led by Adam Harasimowicz, whose experience with period buildings spans more than 25 years, AHKO works exclusively with historic properties where the original fabric is irreplaceable and every decision carries consequence.

Whether assessing a prospective purchase, guiding a complex project, or connecting clients with the right specialists, AHKO acts solely in the client’s interest. We provide independent advice, coordinate expertise, and oversee the process from first conversation to final completion. The client’s building receives the full weight of our attention. We do not divide it.

PHILOSOPHY

"Let the beauty of what you love be what you do."

Every building has a character formed over decades — sometimes centuries. Our work is to understand that character, respect it, and where necessary, treat it with precision.

We do not impose. We do not take shortcuts. We hold to the correct method — because the building, and the client, deserve nothing less.
