Additional Living Space
A Granny Annexe creates essential extra living space for families in Cambridge. It allows for greater flexibility in your home without relocating to a larger property.
We design Granny Annexes that offer extra living space and independence for families in Cambridge.
A Granny Annexe provides a practical option for families in Cambridge needing more room while allowing older relatives to keep their independence. This structure is intended to improve the quality of life for both generations by providing a comfortable and accessible living situation. With our expertise, we guarantee your Granny Annexe will fulfill both functional requirements and design expectations, helping increase your property value.
More families in Cambridge are recognizing the benefits of multi-generational living, where a Granny Annexe serves as an effective response to this growing trend. It enables loved ones to stay nearby while having their own space, which cultivates a supportive family environment.

Constructing a Granny Annexe allows you to optimize the use of your property without needing to upgrade to a larger home. This enhancement not only expands your living space but also boosts the overall worth of your property. Our approach is centered on delivering high-caliber craftsmanship, smoothly integrating your new structure with your current home, focusing on both aesthetics and functionality.


Trenching ruins lawns temporarily. When running water pipes and armoured electricity lines from the main dwelling out to your new Granny Annexe in Cambridge, we must dig deep channels across the turf to prevent winter frost from bursting supply lines. Soil heaps pile up beside the vegetable patch during this stage. Mud happens.
Gravity directs domestic sewage. If the garden dips away toward the rear fence boundary, waste pipes cannot carry wastewater back uphill into the main domestic inspection chamber without installing a mechanical macerator pump system below ground level. That pump hums softly during bathroom flushes.

Using ICF technology, your Granny Annexe will be energy-efficient, delivering ongoing savings on utility expenses. Its sturdy construction ensures durability while adhering to sustainable building practices.
Subfloor voids require constant airflow. Constructing a standalone granny annexe in Cambridge requires maintaining open perimeter vents along the gravel borders, so ground humidity never rises through floorboards into cupboards or creates hidden condensation pockets beneath heavy bedroom wardrobes. Clear fallen autumn leaves away from those exterior grilles.
Garden clay shifts between seasons. Searing summer heat dries the earth out until hairline cracks appear near patio stones, while prolonged winter rain saturates the plot and causes the sod to swell against the foundation footings. Flexible pipe joints absorb this movement underneath the exterior timber cladding so internal copper fittings stay bone dry.

After completing the main structure, we apply the final touches to your Granny Annexe. This includes interior fittings and landscaping, ensuring it blends well with your property.
Overhanging branches create routine chores. Because an outbuilding sits lower than mature suburban oak trees, roof channels collect wet foliage very quickly, which means somebody must climb a sturdy ladder with gloves twice every autumn to scoop out sodden mulch before downpipes overflow. Neglected gutters spill filthy stormwater right over your granny annexe in Cambridge.
Track your secondary consumer units. We mount a separate distribution board inside the utility cupboard so you can isolate power to the rear shower without cutting electricity to the main family kitchen. You should trip the safety switches once every spring with a quick thumb press to verify that the internal breaker springs snap back cleanly.

People frequently forget about clearance around boundary fences, because you need sufficient space to walk around the exterior walls with paint brushes and maintain the gutters without treading directly into neighbouring flower beds or damaging mature hedgerows.
You walk through every room with the lead carpenter to inspect window latches, run taps, and inspect wall finishes; any minor sticking doors caused by timber settling over subsequent months receive a quick site revisit to shave down edges.
Yes, unmapped historical soakaways or thick tree roots near Cambridge properties can stop machine trenching, because striking buried obstacles demands manual digging with shovels and rerouting utility pipes carefully around root balls to prevent structural delays.
Site crews clear the grass, pour concrete foundation piles, erect timber frame wall panels, install the roof membrane, pull internal cables, fit plumbing pipes, and finish with interior plastering before mounting sockets and sanitary fixtures.
