Consultation Room

Welcome to our unique consultation room designed to give you an informative tour of design options. Using our build cost calculator you will be able to obtain a ball park budget feasibility report before starting the architectural design process.

Planning build design

We have compiled some simple guidelines to help you consider the size of your extension and the planning implications. We will advise accurately upon formal quotation.

An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, provided certain limits and conditions are met. As a guide-

  • If the property has NOT already been previously extended
  • Materials must be similar in appearance to the existing house.
  • Side extensions to be single-storey. Width of side extension must not have a width greater than half the width of the original house
  • Single-storey rear extensions must not project beyond the rear wall of the original house by more than 4m if a detached house or more than 3m for any other house.

Please view our showroom below to see some of the options you can select to integrate into your extension design.

Roof Design

A single vaulted roof with Velux windows

A space filled with daylight and fresh air, windows that create a stunning, bright and airy space with real wow factor. When entering a room with a vaulted ceiling you are greeted with a real sense of space. We integrate velux windows to allow light to flood back into the existing part of your property.

A double vaulted roof with Velux windows

Having natural light entering a room from both roof slopes typically gives you sun light during all times of the day. A double vaulted roof will give an enhanced sense of space above all designs. We are able to design a fully glazed gable end for the ultimate luxury finish.

Flat roof with lantern

Using the latest in Flat roof designs we can achieve a stylish finish with a warm feel. A Flat roof glazed lantern is designed to trap as much light as possible, flooding the living space below with illumination as well as allowing occupants to enjoy attractive sky views. They are available with active heat repellent glass to keep room temperatures controlled during hot summer months.

Doors

Bifolding Doors

When fully Open bifolding doors will seamlessly connect outside to in whilst filling the room with fresh air and light. Bifolding doors will give you an uninterrupted garden view. They can be designed to have one door that opens on its own without folding all doors back. Available only in aluminium in a range of colours.

Panoramic sliding doors

When closed these doors will give greater aspect views due to their ability to be designed with much larger glazed sections and slimline frame profiles. Opening orientations can be selected to suit your internally and external layouts. When fully opened they connect outside to in whilst flooding light into the room. Available in aluminium and upvc in a range of colours.

French doors with or without side panels

French doors are a great cost effective way to access your outside space whilst retaining maximum wall space for furniture. You can add full height glazed side panels to allow more natural light to fill your internal space. Available in a range of colors.

Corner Door System

Corner door system

This is a fantastic option that will suit properties with a dual aspect garden or terrace. We are able to design a system where 2 sets of doors or windows meet on the corner of the building leaving just a visual of the frame when fully opened. This design gives a real wow factor to a project enabling the inside to be incorporated with multiple outdoor seating locations.

Full and Semi Open Plan

Full Open Plan

When deciding how open plan to go it can be hard to visualize, typically for a rear single story extension to host a kitchen with island / Dinner / soft/snug seating area then the full length of the existing external wall within the scope of the extension will need to be removed and any internal dividing walls at the rear of the property to allow enough depth to the room. For an open plan kitchen/dinner/snug with island it would generally require 35-40sq meters in total including extension and existing floor space.

Semi

It is not uncommon to design open plan living but with some visual restrictions, for instance not all clients like to have the kitchen visible to their dinners. We can remove parts of existing walls or if there is an existing window on the elevation that is now covered by the extension we can remove the wall below the window to form the new opening. Alternatively simply remove existing French doors to form the opening into the extension.
