DESIGNING YOUR DOUBLE STOREY EXTENSION ONLINE
Online Drawing UK will work alongside you, your requirements and your budget to produce the perfect addition to your home.
As with a single storey extension once we have determined your size and layout all the other considerations will be considered. Any new room in your double storey extension will need to have light, ventilation and means of escape. When designing your extension, the planning limitations must be considered as the size and scale means it must be designed to fit with its environment and neighbouring surroundings.
The regulations are stricter specifically concerning fire escape and structure.
When we design your double storey extension online we advise that you must consider the overshadowing and loss of amenity/outlook form the neighbours of near the boundary.
DESIGN OPTIONS FOR YOUR DOUBLE STOREY EXTENSION
When you know the size of the rooms you want, you need to know how to access and ventilate them the Architectural Designers and Architects at Online Drawing UK can advise on this. We always advise that you make the external of your new extension work well with your existing house. There are limitations in the planning guide for two storey extensions as they have more impact on their surroundings however, we like to work with and enhance existing areas where possible as this means less building work, cost, disruption and impact.
As a rule, clear glazing will generally not be permitted at first floor level within 7 meters of a boundary due to the risk of overlooking yet less consideration is needed on the ground floor and the use of glass can make your extension exceptional.
PLANNING PERMISSION FOR YOUR DOUBLE STOREY EXTENSION
When is comes to submitting a planning application for your double storey extension there are a lot of things to consider, how it impacts the street scene, does it enhance character, does it have negative effect on the neighbours, does it affect light/privacy/amenity? All these are the things the planning officer will be checking whilst making their decision.
With our online architectural services we will give you the right advice on how to achieve your requirements with the best chance of securing planning approval.

Ideas for Your Double-Storey Extension
Posted by Hayman Developments Ltd
on 23rd February 2022
A double-storey house extension can add a considerable amount of living space to your home. If you are considering, or in the process of planning, a two-storey extension, you are probably wondering what is possible with such a project. When you contact our builders in Guildford, Kingswood and the surrounding areas, you enjoy personalised advice and ideas to help you make the most of your home and budget. However, to get you started, we have provided some effective ideas below.
Of course, what is possible with your extension will depend on the space available for the build and your budget. The project may also be subject to planning permission.
Do you want a comfortable, private space for guests, grown children or older family members? A double-storey extension could be the ideal solution. With this type of extension, our builders can construct a self-contained annexe or suite, connected to the main house by a door, corridor or link.
Two stories will provide plenty of space for separate sleeping and living areas, including a kitchen and bathroom.
Reorganise the Layout
Older homes in Guildford, Kingswood and the nearby areas often have awkward, impractical or nonsensical layouts. In many cases, even a small two-storey extension is an effective way to solve the issue. Extra space to the side or rear of your property will allow you to reorganise the floorplan, increase the size of certain rooms and add new rooms/spaces.
This type of project relies on professional refurbishment services alongside the extension itself.
If you are lucky enough to have a beautiful view, why not make the most of it? Our builders can incorporate plenty of glazing into your extension in the form of large windows and glass doors, such as bi-fold doors. It may also be possible to incorporate a balcony. This will allow you to bask in the view from your property.
Generally, this works best on the first floor because the higher position provides far-reaching views. Consequently, you may want to consider moving the kitchen and living areas to the first floor, allocating bedrooms to the ground floor.
An unavoidable benefit of double-storey extensions is that they enable you to create new rooms over two floors. This means you do not have to decide on one use for your Kingswood or Guildford extension.
You have the option to extend existing rooms, combine rooms or create entirely new rooms. Downstairs, you could create a larger kitchen, add a dining room or make the living space open-plan. Upstairs, you could build an extra bedroom or bathroom, create a home office or extend the master bedroom to include a dressing room or en suite. The possibilities are endless but our builders work with you to find the perfect solution.
Inspection of buildings scheduled for superstructure
Survey of buildings scheduled for superstructure
Inspection of superstructure buildings is divided into two stages: preliminary inspection and technical inspection.
Preliminary inspection is carried out during the inspection of the quarter planned for reconstruction, or when choosing a separate object for the superstructure. At the same time, the fundamental possibility of building a superstructure is revealed.
A technical survey is carried out to obtain the initial data necessary for the development of the superstructure project. It is performed for the architectural, structural and special parts of the project.
1. Preliminary inspection
The purpose of the preliminary inspection is to establish the general condition of the building and the possibility of its addition. At the same time, the admissibility of the superstructure must be determined in terms of building rules and regulations, as well as the requirements for the reconstruction of the city and its general improvement.
The starting materials for the preliminary inspection are the master plan of the site at a scale of 1:500 and floor plans at a scale of 1:200 received from the district inventory bureau.
Preliminary examination reveals the following issues:
Upon receipt of all the data and as a result of an external inspection, an act and a schematic drawing of the superstructure are drawn up, an approximate volume and cost of the superstructure are determined. These materials are used for technical inspection and issuance of assignments to the design organization for the design of the superstructure.
II. Technical survey for architectural and planning part
This part of the technical survey should give a detailed idea of the general architecture, distribution of volumes and floor plans of the existing building, show the nature of the external architectural design of the facades of the superstructure and neighboring houses.
The technical survey for the architectural and planning part is usually carried out by the design organization that develops the project of the superstructure.
During its execution, dimensional drawings are drawn up: plans, sections, facades and master plans.
a) Measurement plans
Measurement floor plans are drawn up for all floors, basement, attic and roof on a scale of 1:100. All openings, shoulders, piers, ledges, pilasters, columns, stoves, chimneys and ventilation panels in the walls, wall thickness, etc. are also measured in relation to the dimensions of each measured room. Especially carefully measurements are made of the attic, which is the basis for the superstructure. All measurements are made with an accuracy of 1 cm.
Simultaneously with measurements, familiarization with the purpose and nature of the use of all premises is carried out, indicating the names of the premises on the measurement plans. Items of equipment are indicated: bathtubs, toilet bowls, sinks, stoves, and in basements boilers and central heating boilers. In addition, items of equipment with large loads are indicated, which must be taken into account when calculating the superstructure of the building.
b) Sections of the building
Sections of the building based on the results of measurements are made on a scale of 1:100 or 1:50 and are made according to the most characteristic sections and, necessarily, along stairwells, indicating the thickness of the floors “and the vertical chain of all sizes.
When examining building facades and compiling dimensional drawings, it is also photographed. The dimensions of the prints should be made approximately on a scale of 1: 100; in addition, fragments of the facade and architectural details are given. For corner buildings, photographing the building in perspective is mandatory. Photographs of street facades should also capture the facades of neighboring buildings located closely on both sides.
d) General plan
Based on the results of the measurement, the master plan is drawn up on a scale from 1:200 to 1:500. It should show: built-on buildings, neighboring buildings and adjoining yards that can be used for organizing warehouses and locating construction mechanisms , as well as sections of streets and alleys adjacent to the superstructure. The master plan shows all entrances, entrances and exits from buildings to protect the flow of people and vehicles inside the yard, as well as to protect pedestrians and public transport on the streets adjacent to the building being built on.
III. Technical survey of structures
The purpose of the technical survey of structures is to obtain detailed data on the strength of the building, the technical feasibility of its superstructure and determine the necessary measures to strengthen its individual elements.
Technical inspection of structures of superstructured buildings in Moscow is carried out by a specialized organization – Mosgorgeotrest. In other cities, this work is carried out by commissions of technical and expert councils of city executive committees or design organizations.
Technical inspection of structures consists of examination of bases and foundations, walls, columns, attic floor and roof.
a) Examination of bases and foundations
Bases and foundations under the outer and inner walls and columns of the building are examined by opening the pits.
When examining foundations in open pits, measurements are made of all heights and ledges, as well as the width of the base of the foundation, linking them to the floor level of the first floor (Fig. 16, a, b). At the same time, the quality of laying foundations * material and strength of stone, mortar and pile foundations are determined.
At the same time, the soils located at the entire depth of the pits, as well as the components of the base, are examined. To do this, in addition to the pits, boreholes are laid along the outer perimeter of the building, the depth of which should be approximately 5 m below the base of the foundations.
In all pits and wells, the level of groundwater is determined.
Undisturbed soil samples from each soil layer and stone and foundation mortar samples are subjected to laboratory testing.
b) Inspection of walls and columns
Walls and columns during the inspection are carefully examined from the outside and from the inside in each floor of the building. At the same time, all masonry defects are noted: cracks, buckling, delamination. They measure the width and depth of cracks, install beacons and observe the behavior of cracks. All defects are applied to the wall scans, which are compiled on a scale of 1: 100.
The condition of the masonry of walls and other load-bearing structures and the detected defects are photographed. The solidity of the masonry is determined by tapping, which allows you to identify voids, channels, embedded niches and openings, as well as punching the walls with a jumper or drilling them. All smoke, gas and ventilation ducts in each floor along their entire length from the mouth to the head should be marked on the wall reamers.
The strength of the masonry is checked by laboratory testing of brick and mortar samples. Recently, taking masonry samples with an undisturbed structure has been widely used, for which cylindrical samples are drilled and subjected to laboratory tests. To determine the strength of reinforced concrete load-bearing structures, by means of furrowing (Fig. 1, c), reinforcement is exposed, and then cylindrical concrete samples are drilled. In the absence of such an opportunity, the strength of concrete is determined by more simplified methods (Fizdel’s hammer, shooting method, chisel, etc. ).
c) When examining the columns, it is necessary to measure their profiles and sections on each floor, as well as to identify the structures of the capital supports. In cast iron columns, in addition, a wall is drilled to measure its thickness.
Fig. 1. Inspection of foundations by opening pits:
c) Inspection of the attic floor
When examining the attic floor, on the plan drawn up according to the measurements of the walls and load-bearing structures, the axes of the beams are applied indicating the places of opening and the cross sections of the floor in the opened places.
In the case of a reinforced concrete slab, the strength of concrete, the nature of the reinforcement of beams and slabs, the thickness of the slab are determined and all defects are recorded.
When slabs on metal beams with brick vaults, the strength of the masonry of the vaults and the presence of puffs between the beams in the extreme spans are determined.
For timber floors, carefully examine the condition of the wood and especially the ends of the beams resting on the outer walls. If dry and surface rot is found, the dimensions of its distribution must be indicated on the drawing. In other cases, and especially if mold and signs of fungal infection are found on the surface of the wood, a laboratory study of the affected samples is necessary.
In addition to the inspection of the ceiling from the attic side, the ceilings of the apartments on the upper floor are inspected. In this case, the plaster is examined by tapping, and the exfoliated places are beaten off.
d) Inspection of rafters and roofs
When examining rafters and roofs, a measured plan and sections of the roof are drawn up, indicating the structure of the rafters. The scale of the drawings is taken for the plan 1: 100, for the section 1: 100 and 1: 50, for the details – 1: 20 and 1: 10. When examining the roof, the plan indicates places that require repair or re-coating.
After completion of the inspection of the building, the pits must be backfilled, and the openings of individual structures must be closed and restored.
e) Conclusion on the state of structures
The technical report on the state of structures is drawn up on the basis of survey materials and the results of laboratory tests of soil and material samples.
It consists of two parts: verification calculations of the strength of the supporting structures of the existing building and conclusions about the possibility of a superstructure.
Calculations of foundations and other supporting structures are made for two cases: without a superstructure and with a superstructure.
If, as a result of calculations, it turns out that some load-bearing structures after the superstructure do not meet the strength conditions, then it is necessary either to strengthen them, or change the scheme of the load-bearing structures or reduce the originally estimated number of floors to be built on.
The opinion on the possibility of an add-on must contain the following data:
IV. Inspection of sanitary and special devices
When inspecting the central heating and ventilation system, it is necessary to show on the basement plan the equipment of the boiler room and boiler room, fuel storage, piping and risers. On the attic plan, it is necessary to show the upper wiring, expansion tank, ventilation ducts and chambers. On the floor plans – the location of the risers.
When examining stove heating, if it remains, it is necessary to measure and mark the dimensions of the stoves on the plan, as well as examine their condition.
After examining other types of engineering equipment, all water supply, sewerage, gas, electrical equipment inlets are applied to the master plan, indicating the dimensions of their cross sections. The basement plan indicates the entry points for all external networks, water meters, pumping stations to increase pressure, laundries with their equipment, electrical distribution points, etc.
If available, in the elevator building, the shafts and engine rooms are measured and put on the plan, indicating the brand and load capacity of the lifts, as well as the power of the installed motors and the load capacity of the winches.
