Who This Is For

Expert advice for every
stage of the build

Whether you're protecting a personal investment or managing a commercial development, Theo brings the kind of experience that only comes from 30 years on the ground in Johannesburg and across South Africa.

01

Homeowners

Building or buying a home is one of the largest investments you'll ever make. Get independent, expert eyes on your project — before, during, or after the build — and avoid costly mistakes.

02

Developers

From site assessment to contractor appointment, quality control to final handover — independent oversight that protects your investment and keeps your project on time and on budget.

03

Builders

Compliance, certification, procurement strategy, and process optimisation. A senior construction director in your corner on an advisory basis — without the full-time overhead.

What I Offer

Consulting Services

Every consultation is delivered personally by Theo. No juniors, no handoffs — you get 30 years of direct, practical experience applied to your specific project.

Pre-Purchase Inspections

Certified home inspection before you sign. Identify structural defects and compliance issues sellers don't disclose — with a full written report.

Construction Oversight

Independent quality control and snagging during your build. Regular site visits and detailed progress reports so you always know what is happening on site.

Contractor Vetting

Before you appoint anyone, know exactly who you're hiring. Assess credentials, track record, and capacity so there are no expensive surprises.

Compliance & Certification

Municipal approvals, NHBRC registration, bylaw compliance, and final certification — navigated by someone who has done it hundreds of times.

Budget & Costing Review

Scrutinise quotes, identify overpricing, and understand where value is being lost before you commit to a contract.

Project Advisory Retainer

An experienced construction director available on an ongoing basis throughout your project — for guidance, escalations, and peace of mind.

About

Theo Hassolanidis

Theo began his career in 1991 as an apprentice on construction sites in Johannesburg, learning the industry from the ground up. Over the next three decades he progressed through every level: foreman, site manager, construction manager, and ultimately Director of Operations at Straightedge Construction Management.

Based in Johannesburg, Gauteng, his track record spans over 500 residential homes constructed across South Africa and Zimbabwe, management of 15 commercial shopping centres, and high-end estate builds valued from R5m to R54m. He holds a SAHITA Home Inspection Certificate, is a NABISA registered building inspector (HI 1006), and is NHBRC registered.

Straightedge Consulting is Theo's independent advisory practice — where his expertise works exclusively for the client, not the contractor.
