Turnkey SIP Panel Construction: How Onlysip Works

Building a house often comes with risks: delayed deadlines, an uncontrolled budget, dozens of contractors and the constant need to make technical decisions. That is exactly why the turnkey construction format is becoming increasingly popular.
Onlysip builds turnkey SIP panel houses and takes full responsibility for the result — from the first idea to the handover of the finished house.

What “turnkey construction” means at Onlysip

Turnkey construction is a format in which the client receives a building ready for living or use without getting involved in day-to-day operations.

At Onlysip, this means:

• one contractor;
• one contract;
• clear deadlines;
• a fixed budget;
• a clear result.

The client does not have to coordinate designers, builders, electricians or engineers — the Onlysip team handles all of that.

Stage 1. Consultation and needs analysis

Every project starts with understanding the task. At this stage:

• the building type is defined (residential house, townhouse, commercial property);
• the plot is analysed;
• the budget and timeline are discussed;
• a basic concept is developed.

This helps avoid any mismatch between expectations and the result from the very start.

Stage 2. Design

Design is a key stage in SIP construction. This is where the following are defined:

• energy efficiency;
• the ergonomics of the layouts;
• the exact quantity of materials;
• the final estimate.

Onlysip works with precise drawings, because SIP panels are manufactured for a specific project, not “by eye”.

Stage 3. Manufacturing the SIP panels

Once the design is approved, the house kit is manufactured:

• walls;
• floors;
• roof elements.

Production takes place under controlled conditions, which ensures consistent quality and precise geometry of every panel.

Stage 4. Assembling the house shell

Installation is one of the fastest stages:

• laying the foundation;
• installing the SIP panels;
• floors and roof.

Thanks to SIP technology, the shell of the house can be assembled in a few weeks, regardless of the season.

Stage 5. Building services and finishing

Once the thermal envelope is closed, the following work is carried out:

• electrical installation;
• water supply and sewerage;
• heating system;
• ventilation;
• interior and exterior finishing.

The client can choose the level of completion: “ready for final finishing” or fully turnkey.

Control of deadlines and budget

One of the main advantages of the turnkey format is transparency. Onlysip:

• fixes the estimate at the start;
• works under a contract;
• keeps to the agreed deadlines.

This is especially important for clients who do not want to be involved in the day-to-day supervision of construction.

Who turnkey construction is for

The turnkey format is chosen by:

• families who want to move into their own home quickly;
• investors;
• developers;
• businesses building commercial properties;
• clients who value their time and peace of mind.
