🏡 SAME HOUSE. COMPLETELY NEW FEELING.

🔥 BEFORE & AFTER | Stunning Rear House Extension in New Malden, London!

Sometimes, the best way to fall in love with your home again isn’t to move… it’s to transform it! ❤️

Just look at this incredible transformation in New Malden, South West London!

What was once a traditional rear elevation has been transformed into a beautiful, light-filled living space that brings the indoors and outdoors together.

✨ The highlights?

✅ Stunning vaulted ceiling with a glazed gable feature

✅ Floor-to-ceiling glazing and sleek aluminium sliding doors

✅ Beautiful contemporary design that complements the original house

✅ More natural light, more space and a completely new way of living

✅ A thoughtfully designed extension built for modern family life

🏡 MORE SPACE. MORE COMFORT. MORE VALUE.

🚧 Project Update | Side & Rear House Extension | Eltham, SE9, London

Another exciting transformation is taking shape! Our team at Constructum Code Ltd is making great progress on this side and rear house extension in Eltham, South East London.

🔨 Currently on site:
✔️ Structural steelwork installation – creating the framework for a spacious, open-plan living area.

✔️ Brickwork progressing – bringing the new extension to life with strong, durable construction.

✔️ Structural alterations – preparing the property for a completely new layout.

💷 WHY IS A HOUSE EXTENSION WORTH THE INVESTMENT?

A well-designed extension isn’t just about adding square metres. It’s about making your home work better for you while investing in its future.

🏡 1. Increase Your Property’s Value
Additional living space, particularly a spacious kitchen and open-plan family area, can make your property more attractive to future buyers and potentially increase its market value.

📐 2. Make Better Use of Your Property
A side and rear extension can transform underused space into a beautiful, practical living area without sacrificing the home and neighbourhood you already love.

❤️ 3. Improve Your Everyday Lifestyle
Imagine a bright, open-plan kitchen, dining and living space where the whole family can spend time together.

💰 4. Invest Instead of Moving
With stamp duty, estate agent fees, legal costs and moving expenses, extending your existing home can be a smart alternative to buying a larger property.

✨ 5. Create a Home Designed Around You
Unlike moving into someone else’s layout, an extension gives you the opportunity to create a space that suits your lifestyle, needs and personal taste.

The real value of a house extension?
It’s not just what it adds to your property’s price. It’s what it adds to your everyday life.

💧🏗️ SOAKAWAY INSTALLATION IN HORNCHURCH, RM11 | ANOTHER MILESTONE COMPLETED!

Great construction starts from the ground up! 💪

Another important stage of our major house extension and refurbishment project in Hornchurch, Essex, is progressing nicely!

Our team has been busy installing a new underground soakaway drainage system, designed to manage rainwater efficiently and help prevent future drainage problems.

🔨 What’s involved?

✅ Excavation and ground preparation ✅ Installation of a drainage stone base ✅ Heavy-duty modular soakaway crates ✅ Protective geotextile membrane installation ✅ Preparation for underground drainage connections and backfilling

While the finished system will be completely hidden underground, it plays a crucial role in protecting the property and managing surface water.

Quality construction isn’t just about what you see — it’s about everything underneath! 🏡

At Constructum Code Ltd, we take pride in every stage of construction, from groundworks and drainage installations to complete house extensions and luxury home renovations.

🏡 Another Major Home Transformation Underway in Hornchurch, RM11!

We’ve just started work on another huge rear house extension in Hornchurch, and this one is going to completely transform the property.

The existing rear of the house has been opened up and the structural works are now taking shape. Once complete, the extension will create a much larger, brighter and more practical living space — giving the family the extra room they need without having to move.

There’s still plenty of work ahead, but projects like this are always exciting to watch develop from the early structural stages through to the finished home. 💪🏗️

Looking to extend, renovate or completely transform your home in London or Essex? We can take care of the project from structural works through to the final finish.

Another one completed in Tooting, SW17 🏡

This side return extension has completely changed the way the ground floor feels. What was once unused space along the side of the house is now part of a much bigger, brighter and more practical living area.

A well-designed side return doesn’t always need to dramatically increase the footprint to make a big difference. More natural light, better flow and valuable extra space can completely transform a London home.

Recently completed by the Constructum Code team in Tooting, South West London.

🏠 Mansard Loft Conversion in Tooting, SW17 – Taking Shape

A good loft conversion starts long before the plasterboard and finishes go in. This is where you can really see the structure, planning and workmanship behind the finished space.

Our Tooting SW17 loft conversion is progressing well, with the main timber structure and internal layout now clearly taking shape. The photos show the new floor and roof structure, timber partitions forming the rooms, new window openings bringing natural light into the loft, and the new staircase connection being formed into the existing house.

For London properties where maximising usable floor area and headroom is important, a mansard-style loft conversion can completely change how the top floor works – turning previously unused roof space into a proper extension of the home.

There’s still plenty to do here, but this is the stage where you can already start to see the new home emerging from the structure.

If you’re considering a loft conversion in Tooting, Wandsworth, Balham, Clapham, Wimbledon or anywhere across South London, we can help from the structural stage right through to the final finish.

🏠 FROM UNUSED ROOF SPACE TO A BRAND-NEW PART OF THE HOME | MITCHAM SW19

Another exciting transformation is taking shape in South West London. 🔨

Our team at CONSTRUCTUM CODE is currently working on this loft conversion in Mitcham, SW19 — turning previously unused roof space into practical, comfortable living space designed for modern family life.

A well-planned loft isn’t simply about adding another room. It can completely change how a home works — creating space for a new bedroom, en-suite, home office or private floor without sacrificing the garden or having to move house.

📍 Ongoing works in Mitcham, SW19
🏗️ Structural alterations & roof construction
🪚 New internal layout and carpentry
🧱 Insulation and energy-efficiency upgrades
💡 Preparation for a bright, modern living space
🏠 Designed to maximise every available metre

For many London homeowners, the space they need may already be sitting directly above them.

At CONSTRUCTUM CODE, we deliver loft conversions, house extensions and complete property refurbishments across London, managing the build from the structural stages through to the final finish.

🏡 Liquid Screed Installed – Kitchen Extension in Beckenham

Another important stage completed by CONSTRUCTUM CODE on our kitchen extension project in Beckenham, South London.

We’ve recently installed liquid screed, providing a smooth, level and high-quality floor ready for the next stages of this transformation.

Why choose liquid screed over traditional dry/semi-dry screed?

✓ Excellent with underfloor heating – flows tightly around UFH pipes, helping provide more efficient and even heat distribution.
✓ Superior level finish – creates a flatter and more consistent surface, particularly across large open-plan spaces.
✓ Reduced screed thickness – depending on the specified system, it can often be installed thinner than traditional screed.
✓ Fast installation – large floor areas can be completed quickly and efficiently.
✓ Reduced shrinkage and cracking – when correctly specified, installed and cured.
✓ Perfect for modern extensions – an excellent solution for large kitchens and open-plan living areas.

At CONSTRUCTUM CODE, we manage every stage of your project — from structural works and extensions through to the finishing details.
