Techbuilt House Renovation
Renewing a mid-century home
for family life.
After many years without renovation, this Techbuilt house needed substantial renewal. Dark interiors, an inefficient layout, and cold spaces shaped the brief: update the home for everyday family life while respecting its original architectural character.
The renovation reconfigured the children’s bedrooms, introduced a skylight, modernized two bathrooms, and incorporated updated HVAC, radiant floor heating, and solar hot water tubes.
Project type: Residential renovation

Understanding What Needed to Change
The project brought together repairs, spatial changes, and building-system upgrades. A structurally unsound balcony needed to be removed. Upstairs, two unevenly sized rooms needed to become equal-sized bedrooms for the family’s children. The interior also needed more daylight, updated bathrooms, and a response to cold conditions.
These priorities guided the renovation, connecting decisions about the existing building with the family’s daily needs.
Reworking the Upstairs for the Children
The upstairs layout was reconfigured to create two equal-sized bedrooms from rooms that had previously been uneven in size.
This adjustment addressed a clear family priority: giving each child a comparable amount of personal space. It made the bedroom arrangement better suited to the people using it.
Bringing Daylight and Fresh Air Into the Home
A new operable skylight introduced daylight into the previously dark interior and provided an additional opening for natural ventilation.
Together with the revised layout, it helped create a brighter home, with the flexibility to admit outdoor air when weather conditions allow.
Updating Comfort and Building Systems
The renovation coordinated new HVAC, radiant floor heating, insulation, and replacement windows to address the needs of an aging house.
Blown-in cellulose insulation formed part of the envelope upgrades. Replacement windows retained slim profiles sympathetic to the original design, while solar thermal collectors were incorporated to supplement domestic hot-water heating.
These improvements were developed alongside the architectural changes, bringing the house’s systems and interior spaces into a coordinated renovation.
Integrating Heating, Cooling, and Solar Hot Water
Cold conditions made heating an important part of the renovation. Radiant floor heating was added, and the HVAC was updated as part of the coordinated work to the house.
Solar hot water tubes were incorporated to supplement the boiler’s hot water supply. These system upgrades addressed practical needs beyond the visible interior finishes.
Updating Windows and Insulation
Blown-in cellulose insulation and double-insulated windows formed part of the building-envelope upgrades.
The windows maintained slim profiles similar to the originals, balancing the performance goals of the renovation with the lightness of the house’s architectural details.
Modernizing Two Bathrooms
Both bathrooms were modernized as part of the renovation, extending the renewal to spaces used throughout the family’s daily routines.
Together with the bedroom changes, daylight, and system upgrades, this work brought the home’s interiors into a more coordinated design.

Sustainable Design Strategy
Sustainability in this project was not treated as one feature. It was built into several renovation decisions.
The project included:
Sustainable Strategy | What It Helped Improve |
|---|---|
Modular construction logic | Reduced unnecessary construction waste and supported efficient planning. |
Solar hot water tubes | Helped reduce reliance on fossil-fuel-based water heating. |
Blown-in cellulose insulation | Improved thermal performance using recycled paper-based material. |
Energy-efficient windows | Reduced heat loss, improved comfort, and helped control outside noise. |
Skylights | Brought more natural daylight into the home and supported ventilation. |
Durable material choices | Reduced the need for frequent replacement or high-maintenance finishes. |
Natural ventilation planning | Supported better airflow and indoor comfort. |
The strongest sustainable renovations often come from combining several practical choices rather than relying on one headline feature.
Improving Energy Efficiency
Energy performance was a major part of the renovation.
The home was upgraded with strategies that helped reduce heat loss, improve comfort, and support more efficient daily use.
Key decisions included:
-
Adding high-performance insulation
-
Using blown-in cellulose insulation made from recycled paper products
-
Installing double-insulated windows
-
Maintaining window profiles that respected the original design
-
Using solar hot water tubes to complement the boiler
-
Improving daylight access to reduce dependence on artificial lighting during the day
These updates helped the house feel more comfortable while reducing energy demand.
Renewable Energy Integration
Solar hot water tubes were incorporated to support the home’s hot water system.
Rather than relying only on the boiler, the renovation used solar thermal technology to help reduce fossil fuel demand.
This strategy supported:
-
Lower energy use
-
Reduced reliance on conventional heating systems
-
Better long-term performance
-
A more environmentally responsible renovation approach
For homeowners considering sustainable renovation, renewable energy does not always need to mean a full system overhaul. Sometimes the best approach is to add targeted upgrades that work with the existing home.
High-Performance Insulation
The renovation used blown-in cellulose insulation made from recycled newspaper and other paper products.
This helped improve the home’s thermal performance while using a recycled material.
Better insulation can support:
-
More stable indoor temperatures
-
Reduced heating and cooling demand
-
Improved comfort in winter and summer
-
Less energy loss through the building envelope
-
A quieter interior environment
For older homes, insulation is often one of the highest-impact upgrades because it affects comfort every day.
Energy-Efficient Windows With a Thin Profile
The project included double-insulated windows that improved performance while maintaining a thin profile similar to the original windows.
This was important because the windows needed to do more than save energy. They also needed to respect the character of the house.
The window upgrades helped with:
-
Reduced heat loss
-
Better thermal comfort
-
Improved energy performance
-
Reduced exterior noise
-
A cleaner relationship between old and new design
This kind of decision is important in renovation work: improve performance without making the house feel visually heavy or disconnected from its original design.
Skylights, Natural Light, and Ventilation
A new skylight was added to bring more daylight into the house and support better ventilation.
Natural light can change how a home feels throughout the day. It can also reduce the need for artificial lighting in some spaces.
The skylight helped:
-
Bring daylight deeper into the home
-
Improve the feeling of openness
-
Support natural ventilation
-
Improve daily comfort
-
Connect the interior to changing light throughout the day
For wellness-focused renovation, daylight and airflow are not decorative extras. They shape how a home feels to live in.
A Kitchen Designed for Function, Light, and Airflow
The kitchen renovation included a waterfall-edge island and a layout that supported cross-ventilation and daily use.
A sustainable kitchen is not only about the materials. It is also about how well the space works over time.
For this project, the kitchen focused on:
-
Durable surfaces
-
Clear circulation
-
Better airflow
-
Practical storage
-
Comfortable daily use
-
A clean, modern relationship to the rest of the house
The result is a kitchen that supports family life while staying aligned with the larger sustainability goals of the renovation.
Durable and Lower-Impact Materials
The project used sustainable material strategies where they made sense for the home, the budget, and the design.
Material decisions considered:
-
Recycled content
-
Durability
-
Maintenance
-
Indoor comfort
-
Long-term performance
-
Visual connection to the original house
-
Lower environmental impact
In renovation, the most sustainable choice is often the one that performs well, lasts longer, and avoids unnecessary replacement.
Wellness-Focused Home Improvements
This renovation also supported wellness through practical design decisions.
The project improved:
-
Natural light
-
Ventilation
-
Thermal comfort
-
Noise reduction
-
Indoor air quality support
-
Day-to-day function
-
Connection between rooms
-
Long-term livability
Wellness in a home does not have to look trendy. It can be quiet, practical, and built into the decisions that affect daily comfort.
What This Project Shows
This project is a useful example for homeowners planning a sustainable or wellness-focused renovation.
It shows that a better-performing home can come from a series of thoughtful decisions:
-
Improve the building envelope before focusing only on finishes
