Design & Build
For those who already own land: we design, cost, and build with a transparent price per square metre from the very first drawing.
Our Approach
A clear budget from the first drawing.
Many build projects go over budget because costs are only calculated after the design is finished. We reverse the order: budget and specification are agreed first, then the design responds to them. You know the total before a single brick is laid.

FAQ
Before you start
Can I hire you for design only?
Yes. A design-only package covers architectural, structural, and 3D drawings at 3–5 percent of the estimated construction cost. We still provide a bill of quantities so you can compare contractors.
How do construction payments work?
Payments follow progress: 20% at contract, then staged by milestone (foundation, structure, walls, roof, finishes), with 5% retention released after a three-month maintenance period.
How long does construction take?
A single-storey home of 100–150 m² typically takes 6–8 months; a two-storey 150–250 m² home takes 10–14 months, depending on weather and material availability.
Can the price change midway?
The contract is lump-sum. Changes only occur if you request a scope change (written addendum) or site conditions were not detected during the survey, such as soft soil or rock.
