Extensions

Newnham

Light filled wrap around kitchen extension to Edwardian townhouse in Newnham, Cambridgeshire

 

Architects project brief

Once the owners had decided to extend their Edwardian terraced home, it was very important to them to have an Architect who understood their ideas and could make them a reality .

Harvey Norman Architects are very familiar with Cambridge City Council’s tight planning policies of such terraced buildings within a conservation area. We were able to advise the couple on how they could create their desired outcome within the confines of Cambridge’s planning policy.

The design would expand the kitchen into the side return and create a separate rear linked dining zone overlooking the garden.

 

Design concept and goals

  • Create a fantastic living space that forms a stronger connection between indoor living zones and the garden

  • Fill the side return to radically improve the size and feel of the original interior, while not compromising natural light to the existing rear reception.

  • Create a contemporary feel

Problems to solve for client

  • Lack of a ground floor WC

  • Lack of storage space

Architects challenges

  • Maintain light and access to the existing rear reception room

  • Solve drainage problems by design of new underground system under new ground floor slab

  • Find space for new ground floor WC within a restricted floor plan

  • Obtain the planning approval needed to accommodate the clients goals and objectives despite the property being in a conservation area

Project highlights

The ground floor went from being an small enclosed and dark space to a vast 32m2 / 345 square foot living space - a drastic change for a space that had been untouched for up to 20 years.

The rear patio area was used successfully to integrate the living space with the garden and creating that much desired outside in feel.

To work well, the best open-plan spaces have clearly defined zones. This contemporary zoned open plan divided the new kitchen without affecting the flow of natural light or movement through it.

Together with a glazing manufacturer we developed a bespoke dog leg roof window unit that overcame planning constraints while allowing access and light to penetrate the rear reception room and flood the main kitchen space with natural light.

INDOOR OUTDOOR LIVING

The owner wanted the home to flow, so the kitchen-diner seamlessly leads into the garden

NATURAL LIGHTING

The space is flooded with light from the folding sliding doors at the back of the extension and the glazed roof that runs alongside the kitchen

COOKING ZONE

An open-plan, live-in kitchen diner needs to have defined areas – seating, dining, cooking – even if they’re open to one another. We started by planning which zone the kitchen would occupy

CENTRAL ISLAND HUB ZONE

The best islands are positioned so that they aid easy travel around the kitchen. This one is a focal point that makes the kitchen feel like a friendly sociable space

DINING ZONE

In the evening long pendant lights hung from the ceiling illuminate the dining table with its banquette seating, while large windows overlooking the garden flood the area with natural light by day

 
Our kitchen extension has transformed the way we live in the house. The bifold doors and level patio extend the kitchen out into the garden and add instant impact. From a dark, cold unwelcoming room, the kitchen has become a bright, airy, warm and functional space. It is the new heart of our home.

PROJECT DETAILS

BUILDING STRUCTURE AND CONSTRUCTION SYSTEM

The site was very constrained with limited access through the rear of the garden. The old kitchen floor was completely removed and replaced with a new concrete slab to allow for completely upgraded and new underground drainage, and new under floor heating. Working with the engineer, a new steel fame was inserted to allow for the two most satisfying achievements - the bespoke side return glazing and the green roof.

 

Project post-mortem

When we arrived the kitchen was as one would expect to find at the start of the twentieth century although a lean to extension had been added and the windows replaced. By the time the project was finished, it had been transported to the twenty first century with what we consider a well mannered sleek contemporary design response.

Sawston

open plan rear kitchen extension and bedroom en-suite that brings in the garden in sawston

 
 

Architects project brief

Having lived in this house for several years, the Lawson’s decided it was time for a change. The house had previously been extended to the rear, leaving the kitchen isolated in the centre of the ground floor footprint. It felt dark and cold with the sunlight lost to it for most of the day. The property had a magnificent garden but didn’t make the most of the wonderful views. The Lawsons liked the neighbourhood and didn’t want to move. They wanted to increase the standard comfort of the house. They knew they had to do something radical!

DESIGN CONCEPT AND GOALS

  • Demolish previous rear extension and replace with new larger extension

  • Renovate the existing property to maximise light make the most of the garden views and create a contemporary energy-efficient contemporary design

  • Create a bright and contemporary open-plan kitchen, dining area and sitting area with a strong year round connection to the garden

  • Utilise and extend the existing garden terrace

  • Reconfigure the ground floor layout connecting lounge, new playroom, utility room and existing outbuildings around a new main family hub space which would be approached from a new enlarged hall, with views through to the garden from the front door

  • Boost the space upstairs by creating a new master bedroom en-suite by extending out over a previous single-storey side extension

PROBLEMS TO SOLVE FOR CLIENT

  • Extend the first floor to the side and integrate it seamlessly with the existing roof form

  • Create a coherent, connected new ground floor plan with glimpses and direct views of the garden from all rooms

 

ARCHITECTS CHALLENGES

  • Bring natural light into the centre of the ground floor.

  • Connect the house with existing outbuildings

  • Design of steel lintel over sliding doors in order to create such a wide opening into the garden

Project highlights

Now that the project is complete, the house is not only unrecognisable, it has completely changed the way the Lawson’s use their home. The focus of the house has been completely turned around. The main space is now a zoned kitchen/family room hub which seamlessly links into the garden. The Lawson’s love how different it now looks and feels.

Sandpit Lane

A modern house extension by Harvey Norman Architects St Albans


 

Architects project brief

The MacElvogue's had returned to England after many years working around the world. They came back to a home they had bought 15 years ago, now tired, out of date and unsuitable for the families needs. The client wanted to reorder the ground floor, extend to create a new open plan family room and kitchen, and incorporate a separate self contained granny flat. Bringing light into this dark 1970s property was a key part of the brief. 

 

Design concept and goals

  • Make better use of the existing internal space

  • Cater to the needs of a broad age range, owners, John and Rachel, two teenager and Grandmother in her eighties

  • Create close contact with the redesigned garden through a completely glazed gable with sliding doors and a raised terrace

Problems to solve for client

  • Transform a dark 1970s house to a light and modern open plan style

  • Integrate smart media and computer systems

Architects challenges

  • North facing aspect to the garden

  • Lower level rear garden

  • Fresh planning application needed to accommodate the suggested design


 

Project highlights

This projected resulted in a multi-generational home with a separate but connected granny flat with its own lounge, bedroom, kitchenette, shower room and separate external side entrance and ramp. The conversion of the garage created a new home office. Under floor heating and aluminum faced composite windows were used throughout. 

looking through

The enclosure of the open porch formed a lobby with views all the way through, from the entrance door to the garden beyond

Photo gallery and video testimonial

We are very happy with the space created. It is bright, functional, contemporary, makes a statement and incorporates the garden into the house, or vice versa depending what is required. The annexe currently provides a home for a seriously ill parent and allows separate living spaces with the ability to attend to and oversee care and treatment. It also successfully ensures elderly parent is not isolated.

Project details

Building structure and CONSTRUCTION system

Structural works included lots of relatively complicated internal steelwork, external render and a zinc roof. The construction system included piled foundations, suspended concrete floor and a cut timber roof structure. ID system sliding doors, Glazing Visions roof lights and composite Velfac windows were used to bring light in. 

Sustainability

Highly insulated fabric first approach, space saving and efficient under floor heating and deliberate use of local contractors and suppliers.


 

Project post-mortem

A tired 1970s house was successfully modernised to provide contemporary open plan living. Interiors design work included a modern kitchen, flexible lighting systems, furniture sourcing and brand new doors and windows.

Battlefield Road

house extension by Harvey Norman Architects St Albans


 

Architects project brief

The clients had lived in a large 1930s arts and crafts house for a while. The main pain point was a small kitchen not suited for 21st century living — it was set to the side of the dining room as is typical of houses of this period. There had also been a small post war utility room that created a fractured layout that was difficult to use and disconnected from the rear garden.

 

Design concept and goals

  • Maximise natural light
  • Create a terrace for the house
  • Visually connect the house with the garden

Architects challenges

  • Due to the East, West orientation of the house, only the rear of the property saw morning light
  • The change in levels from the main house to the garden below

PROBLEMS TO SOLVE FOR CLIENT 

  • Poorly functional small kitchen
  • Small family bathroom in need of a redesign
  • Create a new utility room with its own side access
  • Keep existing low ceiling height in the first floor bedrooms and maintain uninterrupted 2.7m height from the existing ground floor to the new
  • Move existing WC to allow the adjacent front room to be enlarged

Project highlights

  • Lots of natural light from two sides and above — achieved with Kloeber doors and glazing vision rooflights
  • A large open plan style was cleverly zoned into modern kitchen, dining and living spaces
  • Layered lighting schemes emphasized zoning, task and feature lighting
  • Stylish lightly coloured stone flooring added to the spacious feel
  • Luxurious and high quality family bathroom achieved with CP Hart fittings

This project connected a previous rather long and dysfunctional 1970’s side extension to this mid war house. The side extension was linked to the existing kitchen and utilities by creating a new much larger zoned light and airy family room. This space including a kitchen, dining and seating area gave three times as much space for day to day living and entertaining.
